This is because lymph enters the lymph nodes from the collecting ducts, where it is filtered and monitored by immune cells.
From the lymph nodes, lymph travels through larger vessels called lymphatic trunks, which eventually drain into the bloodstream.
Choice A is wrong because veins are blood vessels that carry blood back to the heart, not lymph.
Plasma is the liquid part of blood that contains proteins and other substances.
Choice B is wrong because capillaries are the smallest blood vessels that exchange materials between blood and tissues, not lymph.
Blood supply is the delivery of blood to organs and tissues.

Choice A is wrong because it contradicts the definition of a hormone.
Hormones are not just any secreted molecules, but ones that have specific effects on cells with matching receptors.
Correct Answer is A
Explanation
It is a major component of the lymphatic system and contains T and B lymphocytes.
Choice B is wrong because the spleen does not produce T lymphocytes, but rather stores them.
T lymphocytes are produced in the thymus.
Choice C is wrong because the spleen does not filter lymph, but rather blood. It traps bloodborne microbes and produces an immune response to them.
Choice D is wrong because the spleen consists of one lobe and is located in the upper left abdomen below the diaphragm.
The description in choice D matches the thymus, not the spleen.
The normal size of the spleen in adults is about 12 cm long, 8 cm broad, and 3-4 cm thick, weighing about 200 g.
The normal range of splenic index (the product of length, width, and thickness) is 120-480 cm.
