The veins that receive lymph from the two terminal lymphatic vessels are the:
Carotid veins
Subclavian veins
Brachial veins
Pulmonary veins
The Correct Answer is B
A. Carotid veins are not the primary veins for receiving lymph from lymphatic vessels. Carotid veins are associated with the head and neck, but they are not the main vessels where lymph drains.
B. Subclavian veins are the correct answer. The lymphatic system drains lymph into the subclavian veins at the junction of the internal jugular vein, where the lymphatic ducts (such as the thoracic duct and right lymphatic duct) empty into the bloodstream.
C. Brachial veins are associated with the upper arm and do not receive lymph from the terminal lymphatic vessels.
D. Pulmonary veins are responsible for carrying oxygenated blood from the lungs to the heart, not lymph.
