Explanation
A. It is the air in the lungs after maximal inhalation: Total lung capacity (TLC) refers to the total amount of air the lungs can hold after maximum inhalation.
B. It is the quantity of air that a person can move into or out of the lungs: This defines vital capacity, not total lung capacity.
C. It is the amount of air that remains in the lungs after a normal tidal expiration: This describes functional residual capacity, not TLC.
D. It is the maximum volume of air that can be exhaled from the lungs after maximum inhalation: This is the definition of vital capacity (VC), not total lung capacity.
Correct Answer is A
Explanation
A. Enters the superior or inferior vena cava; exits the pulmonary arteries: Deoxygenated blood from the body enters the heart through the superior or inferior vena cava and flows into the right atrium. It then passes into the right ventricle and exits through the pulmonary arteries to the lungs for oxygenation.
B. Enters the aorta; exits the pulmonary veins: The aorta and pulmonary veins both handle oxygenated blood, not deoxygenated blood, making this incorrect.
C. Enters the superior or inferior vena cava; exits the coronary arteries: The coronary arteries supply the heart muscle itself with oxygenated blood, so this is incorrect for deoxygenated blood.
D. Enters the pulmonary veins; exits the aorta: Both the pulmonary veins and the aorta are part of the oxygenated blood circuit, making this incorrect for deoxygenated blood flow.
