Emphysema is a health condition in which the lungs can no longer expel carbon dioxide normally. as a result, a person who has emphysema may have high blood acidity levels. the body process that would attempt to return the blood ph to normal so that cells could function properly is called a. active transport b. adaptation c. homeostasis d. acidosis

The correct answer is homeostasis.

Homeostasis refers to a self-regulating procedure by which biological systems seem to sustain stability while amending the conditions, which are optimal for survival.

This dynamic state of equilibrium refers to the situation of optimal working for the species and involves many variables, like fluid balance and temperature of the body, being maintained within some kind of pre-limits.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
