Answer:
What is the Protein within the RBC that is composed of four protein chains and carries O2 molecules
for transport to tissues by binding it to iron?
,Question:
15. Respiratory functions
Answer:
intake oxygen and remove carbon dioxide, maintenance of body heat, maintenance of PH.

16. Inhalation/ exhalation active or passive?
Answer:
inhalation is active, exhalation is passive
Question:
17. Gaseous Diffusion
Answer:
gas moves from areas of high pressure to low pressure.
Question:
18. Alveoli
Answer:
carbon dioxide and oxygen move in and out of the due to pressure differentials between gases.

19. as altitude increases, blood oxygen saturation decreases, leading to hy- with an increase in
altitude? poxia.
Answer:
The pressure differential between oxygen molecules across the alveolar- capillary membrane is
critical. How does this affect a crewmember
