#Small note: Respiration is the cellular event of chemical exchange in the alveoli. Ventilation is airflow and pressure.

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)
