Question

Which of the following features of Mammalian respiratory epithelia contributes to making gas exchange very rapid? Choose all that apply. Epithelial cells of the alveolar sacs are thin. The PO2 gradient is steep Alveolar sacs are surrounded by elastic connective tissue. The total surface area of alveolar walls is large. Airflow counters blood flow across the respiratory membrane. Endothelial cells of the alveolar capillaries are thin.
