Document Summary

Respiration: provides o2 to the blood because cells require o2 to produce atp in cellular respiration, removes co2 from the blood since it is a waste product of metabolism, regulates [h+] (blood ph) Kidneys are very important in controlling blood ph too because blood needs to hold a rather stable ph: speech, microbial defense.

Angiotensin converting enzyme is found in high concentrations in lungs to control the amount of. Lungs also metabolise and get rid of inhaled anesthetics. Influences arterial concentration of chemical messengers angiotensin ii: traps and dissolves small blood clots. Because we have so many capillaries, if one is blocked by a clot then blood will take another route until enzymes dissolve the clot. Lungs suspended in thoracic cavity surrounded by chest wall: lungs, chest wall, and diaphragm are elastic structures.
