a. Neurologic system
b. Endocrine system
c. Pulmonary system
d. Immune system
e. Cardiovascular system
f. Hepatic system

The neurologic system controls respiratory drive; the respiratory system controls delivery of oxygen to the lung capillaries; and the cardiac system is responsible for the perfusion of vital organs. These systems are primarily responsible for the adequacy of gas exchange in the body. The endocrine and hepatic systems are not directly involved with gas exchange. The immune system primarily protects the body against infection.
