How does tb affect gas exchange
WebFor gas exchange to be efficient, the volumes involved in ventilation and perfusion should be compatible. However, factors such as regional gravity effects on blood, blocked alveolar … WebHow does this affect gas exchange? The alveoli have insufficient ventilation, so the partial pressure of the oxygen in the alveoli decreases. this causes pulmonary capillaries of alveoli to constrict, redirecting blood flow to other alveoli Compare and contrast adult hemoglobin and fetal hemoglobin.
