At rest, your lungs wish to deflate, and your ribcage expands outwards.
#better drawn mdzs#mdzs#wei wuxian#yiling laozu#Happy Friday the 13th!#This is scientific fact btw!#Ventilation operates through a series of active and passive forces#The active forces being muscular contraction with inhalation and exhalation having their own set of muscles.#but the interesting part is the passive forces at work:#The lungs have a certain level of elasticity to them - meaning the more they expand the more the those elastic forces are functioning-#-to try and return the system to rest (exhalation passive forces). Your diaphragm is the main force - pushing against the lungs at rest.#Your ribcage on the other hand is under a state of being pulled outwards. It *wants* to be as open as possible.#These to contradicting forces create a constant push and pull which assists in the ebb and flow of air. Most significantly with exhalation.#Now that being said - the primary action of inhalation ventilation is through control centers in your brainstem.#If you lose connection to that due to trauma you're going to need ventilation assistance.#Small note: Respiration is the cellular event of chemical exchange in the alveoli. Ventilation is airflow and pressure.#They are both important but also very different things. Sadly used interchangeably.#My anatomy nerd brain is screaming over the inaccurate ribcage...but its...recognizable. I will get it right one day.#Okay nerd rant over (I cut out a lot of stuff about pressure gradients. They are cool. To me.)#This is a redraw of an mspaint doodle I made back in april. I yearn to make the Yiling Laozu eerie as he deserves#Tear that bitch (affectionate) apart!#Been playing around with hatching for a while and its amazing how many styles there are! Not sure I'll stick with this one (but it was fun)

Why are ppl scared to call it what it is and say we’re still going thru covid on top of seasonal illness. Like. That’s pretty important right. I was watching the news and they were like oh yeah we have an unprecedented number of flu cases “as well as other sicknesses” without actually saying Covid. No announcement abt vaccinations or masking or anything. Also if I hear someone joking abt “war flashbacks” for mentioning covid I fucking hate u

any other disabled people feel like they're losing their mind trying to get anyone around them to give a flying fuck about protecting others. i had a blood test today and the nurse had a cold and was sniffing and snuffling all over the place, not wearing a mask, not making any effort to turn away, and i'm sitting there just as fucking immunocompromised as i was four years ago when they were all in PPE and i'm wondering what the fuck's going on tbh

What Is an Endemic Disease? What Does It Mean for COVID-19?
What does endemic mean? The Centers for Disease Control and Prevention (CDC) says an endemic is “the constant presence and/or usual prevalence of a disease or infectious agent in a population within a geographic area.” To put it another way, an endemic disease is consistently present, but it spreads at predictable rates that can be managed by communities.
Old article, but people continue to use the word "endemic" while seemingly not understanding what it means, or rather, taking it to mean that we should shrug our shoulders and do nothing. Neither learn nor apply anything new.
The fact that it took decades for other mitigations to be put in place historically (whether it's clean water, hand-washing, or HIV/AIDS activism and treatments, etc.) seems to be an excuse to take no action in the meantime, and to bully and endanger those who try.
"Managed by communities" above means to actually use the layered mitigations that have been proven to work, with copious data now, against an airborne virus and vascular disease with a ~10-20% chance of debilitating long-term post-effects.

do you paint traditionally? i think your art style would look beautiful in oils. theres some pieces of yours i look at and think: one day i will see this artist in a museum! not that that wouldnt happen with your digital art too.
First of all this is incredibly sweet and made my put my hands on my face. Thank you!
And I do paint traditionally! I haven't for a few months now that I've moved away and I no longer have the time nor the space to (I'm not studying art :P) but I've posted some of my traditional work :]
Here are more that I've never posted, though

how does venting work in among us
Tumblr media
because i thought that the impostor were using their shapeshifting abilities to be able to fit into the vents
Tumblr media
but then among us added roles and made it so crew members could vent
Tumblr media
but also only if they're an engineer
Tumblr media
is it like
the engineers are the only ones that know how to crawl?
is there multiple branching pathways in the vents that only someone who repairs the ship know how to navigate?
polus and the fungle make this even more confusing
on polus, it's just holes, i don't see why they only some people can use them
Tumblr media Tumblr media Tumblr media
and the fungle, a plant eats you, then a different one spits you out?
Tumblr media
how does that work?
are the impostor able to travel through the roots of the plants?
how do the engineers do it?
Tumblr media
if the engineers can do it why can't the rest of the crew?
Tumblr media
well actually maybe the crew shouldn't jump into giant plants that can eat you whole
but still why is it that the crew can vent but only when they're engineers, which doesn't even make sense for 2/5 maps
none of this makes sense

If we wanna talk about "unskilled labor" let's talk about landlords who rake in thousands of dollars a month and will refuse routine repairs and maintenance because they don't know how a fucking house works

Guys I'm testing your Doll Knowledge....
Как они по-русски любят говорить... 'Ой, я должна была предположить, что кто-то сможет убежать через вентиляцию, используя выброшенные зеркала как ступеньки.'
