Which of the following is not a function of the spleen?
Chyle drainage
Blood filtration
Destruction of old red blood cells
Blood storage
The Correct Answer is A
A. Chyle drainage is not a function of the spleen. Chyle, a milky fluid rich in fats absorbed from the intestines, is transported by the lymphatic system — specifically through structures like lacteals and the thoracic duct — not the spleen.
B. Blood filtration is a key function of the spleen, as it removes pathogens and debris from the blood.
C. Destruction of old red blood cells occurs in the spleen, which acts as a graveyard for aging or damaged red blood cells.
D. Blood storage is also a spleen function; it can store blood and release it in case of hemorrhage or increased demand.

Correct Answer is C
Explanation
A. They have thin walls – Lymphatic vessels have thin walls, similar to veins, which allow for the passage of lymph.
B. They can contract to propel lymph – Lymphatic vessels do have the ability to contract, aided by smooth muscle and valves, which helps propel lymph in the right direction.
C. They transport lymph to the tissues – This statement is incorrect. Lymphatic vessels carry lymph away from the tissues (not to the tissues) and toward lymph nodes and eventually to the bloodstream.
D. They are blind-ended – Lymphatic capillaries are indeed blind-ended, meaning they begin as closed-ended tubes that absorb interstitial fluid from tissues.
Correct Answer is C
Explanation
A. Chyle is a type of lymphatic fluid rich in fats absorbed from the intestines, but it is not the primary basis of all lymphatic fluid.
B. Secretions of lymph nodes contribute immune cells and filtering functions but do not form the main component of lymph.
C. Plasma is the correct answer. Lymphatic fluid originates from interstitial fluid, which in turn is derived from plasma that leaks out of capillaries. This fluid enters the lymphatic system and becomes lymph.
D. MALT (Mucosa-associated lymphoid tissue) is involved in immune responses in mucosal membranes but does not form the basis of lymphatic fluid.
