Document Summary

Q: what is the general function of respiration? (2) A: to o(cid:271)tai(cid:374) o2 for us (cid:271)(cid:455) the (cid:271)od(cid:455)"s (cid:272)ells a(cid:374)d to eli(cid:373)i(cid:374)ate the co2 the (cid:271)od(cid:455) (cid:272)ells produ(cid:272)e + gas exchange. Q: respiration have two separated but related processes. Q: respiration also plays a role in the ____-____ balance. A: it encompasses the intracellular metabolic reactions involving the use of oxygen to derive energy (atp) from food, producing carbon dioxide as a by-product. Q: what are the 4 steps of external respiration. A: capillaries: ventilation between the atmosphere and air sacs (alveoli) in the lungs, exchange of o2 and co2 between air in the alveoli and the blood in the pulmonary. 3. transport of o2 and co2 by the blood between the lungs and tissues. 4. exchange of o2 and co2 between the blood in the systemic capillaries and the tissue cells.
