I know it's a little out of place here, but I'm very proud of my drawing for General Pathology, and I had to show you.

It is a cut of a kidney seen from the inside and a nephron. I have another one that I did for Gynecological Pathology, but if I publish it they ban me XD.

"Don't you see?" She addressed the entire room. "We either fight here and win, or die trying, because there won't be anything left if we fail. This is the moment. This is the crucial point where the future of yet unborn generations will be decided either by our action or inaction. For centuries to come, people will look back at this time and rejoice at our courage or curse our weakness."

Lesson

A short story, by Ivy Michaels.

The following story contains a graphic depiction of surgery, with all the drugs and violence involved. It also includes graphic descriptions of pain. That is, in fact, the idea behind writing it.

And yes, this is smut.

“You know, dear, you’ve been such a good pupil these last few weeks.” Her voice comes to me through the curtain. I hear the click-clack of her heels on the linoleum floor, making an off-beat rhythm with the beeps and hums of monitors and pumps. She draws closer, and continues, “I think we’ve worked enough on theory, it’s time to move on to your practical lessons.”

The curtain is drawn back and I open my bleary eyes to see her. She’s dressed in the uniform she always wears. Rubberized olive drab canvas, sleeves pulled over the gloves, all seams taped over. Her face is mostly obscured by a surgical mask. Her hair is tied up under a paper hair net, though I can see a few strands of raven hair. All this despite the hood she wears with the clear face plate. I think she likes hiding her face from me, she’s never let me see it. Not all of it, not all at once.

“My darling,” she says, as kind and bubbly as ever, “you did so well on your nephrology unit last week, that I thought I’d give you a little treat!”

Images flash in my head. A slideshow of dissections. Parts of organs labeled. Ureter, renal artery, nephrons.

“Ah!” she says, approvingly, “I see you remember well!”

This is how it always is. She always knows what I’m thinking. I don’t know how that works. I have vague memories of sitting in a chair with my head in a device to immobilize it, but I can’t remember if that was a dream or an actual procedure. Memories are like that here. I know I haven’t been here long, but it feels like forever.

“I know you don’t understand, honey,” her voice falls to a gentle coo, “but don’t worry, I promise you will, eventually.”

I don’t mind it here, really. She’s very sweet to me. She teaches me things about myself I never knew. The other day, I think, she showed me where the vagus nerve is. I had forgotten what the bones in my palm are called, so she showed me how easily I could be disabled simply by applying a small electric shock to that nerve. The name of the bones was “metacarpals”.

That might seem harsh but she means well. Not in the sense that I’m rationalizing, either. I may not be able to remember why I’m here, but I sense that I am here by choice. I know it in my core It is, in fact, the only thing I know for certain.

“So, dear, are you ready?” she asks, “I’ve prepped room #5. The one with the seafoam green tile. I know it’s your favorite."

I hardly have to think about an affirmation. The bed thunks beneath me as she releases the brakes and begins rolling me into the hallway. One of the few things I recall from my time outside is this sensation, when I was very small, of being rolled through a hospital corridor on a cot. I can’t remember why I was there.

We turn a corner and my eyes come to rest on a pair of two-way doors, steel painted beige, with thin sheets of stainless to protect the doors from the impact of a gurney. Small windows of reinforced glass. The doors swing open and the cart jolts with the transfer of momentum.

Inside there are three other figures, all dressed identically to her, save for tinted, opaque faceplates. They are standing off to the side. Sometimes, they observe closely, sometimes they aren’t present at all, but always they listen to her commands, and never do they touch me without her explicit instructions. It makes me feel safe, knowing that she is the one in charge.

“Alright, dear, hold still while we move you to the table.” She grabs me by the shoulders, gently cradling me. One of the other figures grasps my legs, and together they move me onto the operating table. A second figure connects an IV line to the port in my arm. There’s a large mirror on the ceiling, so that I can observe.

“For this one, dear, you have a choice. Would you like the pain, or no?”

I want the pain. I always want the pain.

“Very well then. Paralytic only.” She nods to one of the figures, who hangs the appropriate bag on a hook above the table.

“Flex your fingers, dear.” She commands. I comply. After a few seconds I experience the sensation, curious as always, of being unable to move. An electric thrill of anticipation flies through me. It is almost time.

She unbuttons my gown, starting from the top, exposing first my breasts, then my stomach, and finally my groin. “Oh!” she says, “someone’s excited.” Of course I am. She’s never taken off my whole gown. This is something special.

“Oh,” she says, “I almost forgot, we’ll need to intubate.” One of the trio of assistants wheels over a cart with a ventilator. She takes a tube from it and tilts my head back, ever so sweetly. I feel the tube go down my throat, down past the epiglottis, my body trying to fight but finding itself disarmed by the paralytic. For ever so brief a moment I cannot breathe, and then I feel the beautiful sensation of air returning into my lungs.

“You did so well. I’m so proud of you!” she praises me as she applies tape hold the breathing tube in place.

“You know, this hood is very warm.” She says, and reaches up to unzip the hood from her suit. This is new. She hands the hood to one of the assistants, before bending down next to my ear and whispering, “I’m so proud of you.” And then she kisses me on the forehead, through her mask.

Standing back upright she says, “Okay, I’m going to make an incision…here.” she traces a line gently with her finger, from my sternum down, around my navel, ending at my pubic bone. “Are you ready?”

I am so ready that, if not for the paralytic, I think I might sob. She looks at me through the overhead mirror. I can see her smile through the surgical mask. “Very well then.”

She presses the scalpel to my flesh. Just a light pressure at first. Then, a stinging, and finally the burning, electric sensation of nerve endings being torn from their neighbors. It is the most incredible, all-consuming feeling. I can feel my brain trying desperately to force my limbs to push her away, to run from the room. I don’t want to, but I cannot, by myself, suppress the survival instinct. I feel tears well up in my eyes and flow down my cheeks.

“Very, very good.” she tells me, reaching up and stroking my hair. “You’re doing so well. Now, let’s see if you can tell me the names of everything in here.”

And gently, ever so tenderly, she slips her hand into my abdomen. I can’t remember what sex feels like, but I’m sure it doesn’t even come close to this. Knowing she’s so close to me is intoxicating. I feel her hand touch my small intestine.

“Very good!” she says, as she works her way up, to my stomach.

“That’s right” before moving on to my liver.

“That’s three for three! Very good!” the warmth in her voice fills my heart with joy. She’s so gentle. The pain is incredible, but it feels so good, because I know she’s the one causing it. I know she loves me, and I love her.

“Moving further down,” she continues, pulling her hand out, much to my disappointment. “Oh dear, don’t worry, I’ll be right back in in one moment”

And once again she plunges into my abdomen. The white-hot fire of the incision has faded slightly to merely red-hot smoldering. I feel her touch my sigmoid colon. “Excellent.”

Her hand moves to my left kidney. “Very good!”

I feel her grasp my bladder. “Perfect.”

She sighs, “It’s a shame I can’t reach your prostate from here, love.” A laugh.

“But that will be for later.” She stands and looks at one of the assistants. “Okay, sew her back up. Be gentle.” She must sense my disappointment, though, because she turns back to me. “Oh don’t worry, my dear, there’s one more thing left.”

It takes a while for the assistant to finish closing the incision in my abdomen. Time moves strangely in here, so I couldn’t say how long. By this point my body has numbed the incision area all on its own, leaving only the faint pulling and tugging of the sutures to be sent to my brain.

She walks back over and stands at the foot of the table. “You did so well there. I’m so proud of you. As a reward for how well you’ve done so far in your lessons, I’m going to perform one last procedure today.”

And with her most gentle touch yet, she pulls my legs to either side. “I know how much these bother you.” For a moment I panic, but she’s quick to reassure me. “Oh, not your legs, hon.” And it clicks.

“I’m going to cut right here.�� she traces a line down the center of my scrotum. “And you’ll be rid of these forever.”

I feel the cold steel of the scalpel press in. The faint sting followed by the roaring thunder of pain. That high, heady feeling of endorphins rushes in again. I feel her, very faintly, reaching in and grabbing my right testicle.

"So, I know you hate these things. I hated mine, too.” She squeezes, hard, sending yet another rush of pain up and into my abdomen. “So I figured, why not simply take them away?” I feel the odd sensation of cold steel on my vas deferens. “Are you ready?”

I am.

I feel, for the briefest moment, a zing of pain and then the loss of signal that indicates a part of my body was severed. I feel her tying off the end.

“That’s one down. Time for the other.” Another hard squeeze on my left. “You’re taking this all so well! I’ll be sure to reward you when you’ve healed.” That same zing, that same loss of signal. I feel tears welling up. Not tears of pain, but joy, and love. I feel the repeated sting and tug and sting and tug as she sutures me back up.

“Okay love,” she says, at my side now, stroking my hair. “we’re going to push the painkillers now, and bring you out of the paralysis.” And with that, I feel the rush and the heady fuzz of opioids entering my system, the relief washing over me like a cool shower on a hot summer day.

“I want you to flex your fingers. Just keep flexing them.”

At first I can’t. I try and I try. But slowly, I start to feel them twitching, and after not too long I feel myself able to make a weak fist.

“Very good. You’re such a good girl.” Before I can say or even think anything, she reaches up, and removes first her cap, and then her hair tie. A shoulder-length crop of raven curls falls out. And then, to my amazement, she reaches up to her ear and removes the mask.

I see her face for the first time. I’m able to take in her sculpted jaw, her chin. She has a beauty spot on her right cheek. Her green eyes fill with warmth and, for the first time, I see her smile. “Let’s get that tube out.” She removes the tape on the tube. “Okay, I need you to take a deep breath. On three, I want you to exhale as hard as you can. One, two, three!” I blow and the tube slides out. I cough quite a bit.

Rather uncharacteristically, she tosses the tube aside. “You did so good today babe.” She comes in close, leaning over me, and our lips meet. Her kiss is so soft, so tender. I’m so lucky to have her. After what might be hours, or maybe no time at all, she pulls away.

Shakily, with a voice that hasn’t seen use in a long time, I say, “Thank you, Teacher.”

What are the Functions of Nephron? 

There are at least one million nephrons in each kidney, and together, they drive the kidneys, collectively serving as the functional unit responsible for filtering blood and regulating the body’s fluid balance. As we explore the structure and functions of nephrons, and parts of nephrons, we actually shed light on their significance in maintaining overall health.

Importance in Kidney Function

As you may observe in the Nephron diagram, these play a crucial role in maintaining the body’s fluid balance, regulating blood pressure, and eliminating waste products. They work in harmony with blood vessels and other components of the kidney to ensure proper filtration and excretion of metabolic waste.

Structure of Nephron

There are two kinds of nephron, superficial cortical nephrons that comprise 70-80%, and the rest being juxtamedullary nephrons. A look at the parts structure of nephrons, we realize that they consist of two primary components: the renal corpuscle and the renal tubule.

Renal Corpuscle

Among the parts of a nephron, the renal corpuscle is a key one and also the initial site of blood filtration. It spearheads the core function nephron, through glomerulus, a network of tiny blood vessels, and the Bowman’s capsule, which surrounds the glomerulus. The glomerulus acts as a sieve, allowing small molecules such as water, electrolytes, and waste products to pass through while preventing the passage of larger molecules such as proteins and blood cells.

Renal Tubule

The next among the major parts of a nephron is renal tubule, a long, convoluted structure that continues from the Bowman’s capsule. It consists of several segments, each with specific functions. These segments include the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.

Functions of Nephron

The Nephron functions are explained below,

Filtration

Filtration is the first step in urine formation and occurs in the renal corpuscle. As blood passes through the glomerulus, the high-pressure forces water, ions, nutrients, and waste products out of the blood and into the Bowman’s capsule. This fluid, known as the filtrate, contains substances that need to be selectively reabsorbed or excreted.

Reabsorption

Reabsorption takes place primarily in the renal tubule. Essential substances, such as glucose, amino acids, and water, are selectively reabsorbed into the surrounding capillaries to be returned to the bloodstream. This process ensures that vital molecules are retained in the body, maintaining balance.

Secretion

Secretion involves the transfer of additional substances, such as excess ions, drugs, and toxins, from the blood into the renal tubule. This process allows the nephron to regulate the concentration of certain substances in the body, aiding in the elimination of waste and maintenance of homeostasis.

Excretion

Excretion is the final step in urine formation. After the filtrate has undergone reabsorption and secretion processes in the renal tubule, it reaches the collecting duct. Here, additional water and solutes are reabsorbed or excreted based on the body’s needs, resulting in the formation of concentrated urine.

Types of Nephrons

There are two main types of nephrons: cortical nephrons and juxtamedullary nephrons. 

Cortical Nephrons

Cortical nephrons are the most abundant type, comprising approximately 85% of all nephrons. They are primarily located in the outer region of the kidney cortex and have a shorter loop of Henle. These nephrons are involved in maintaining overall body fluid balance.

Juxtamedullary Nephrons

Juxtamedullary nephrons are located closer to the medulla of the kidney and have a longer loop of Henle. They play a crucial role in producing concentrated urine and are involved in the body’s water conservation mechanisms.

The nephron, as the functional unit of the kidney, performs vital tasks to maintain fluid balance, regulate blood pressure, and eliminate waste products from the body. It is an intricate system that ensures the proper filtration, reabsorption, and secretion processes required for overall health and well-being.

Understanding the structure and functions of nephron, and their types provides valuable insights into the complex processes involved in urine formation. The nephron’s remarkable capabilities enable the body to maintain a delicate balance and eliminate waste effectively. By comprehending the significance of nephrons, we can appreciate the intricacies of the human body’s filtration system.
