Where does the circulating lymph return to cardiovascular circulation?
Subclavian vein
Carotid artery
Ascending aorta
Jugular vein
The Correct Answer is A
a. Subclavian vein: The lymphatic system drains lymph into the cardiovascular system at the subclavian veins, specifically where the lymphatic ducts (thoracic duct and right lymphatic duct) empty.
b. Carotid artery: This is an artery supplying blood to the brain, not involved in returning lymph.
c. Ascending aorta: This is the part of the aorta that rises from the heart and distributes oxygenated blood, not involved in lymph return.
d. Jugular vein: While close to the lymphatic ducts, lymph specifically drains into the subclavian veins.
