From the collecting ducts, lymph enters:
Veins; plasma.
Capillaries; blood supply.
Lymph nodes; lymphatic trunks.
Arteries; serum and becomes part of the.
The Correct Answer is C
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 D is wrong because arteries are blood vessels that carry blood away from the heart, not lymph.
Serum is the liquid part of blood that remains after clotting.

Correct Answer is D
Explanation
Atrial natriuretic peptide (ANP) is a hormone secreted by the heart when the atria are stretched by high blood pressure or volume.
ANP has multiple effects, such as increasing urine and salt excretion, lowering blood pressure, and opposing the renin-angiotensin-aldosterone system.
Therefore, ANP inhibits the release of renin and aldosterone, which are hormones that increase blood pressure and sodium retention.
Choice A is wrong because ANP is not released from the adrenal cortex but from the cardiac atria.
ANP does not stimulate atrial hormones but rather inhibits them.
Choice B is wrong because ANP is not stimulated to release when blood volume decreases, but when it increases.
ANP acts to reduce blood volume by promoting diuresis and natriuresis.
Choice C is wrong because ANP does not raise blood pressure, but lowers it. ANP acts as a vasodilator and reduces peripheral resistance.
Correct Answer is B
Explanation
Veins are the type of blood vessel that holds the greatest volume of blood and serve as reservoirs for blood.
According to 1, veins contain about 70-80% of the blood volume in circulation.
Veins are also called capacitance vessels because they can expand and store more blood when needed.
Choice A. Capillary is wrong because capillaries are very thin and narrow vessels that allow the exchange of gases and nutrients between the blood and the tissues.
Capillaries have a very small volume compared to veins.
Choice C. Arteriole is wrong because arterioles are small branches of arteries that regulate blood pressure and blood flow to the capillaries.
Arterioles have a higher resistance and lower volume than veins.
Choice D. Artery is wrong because arteries are thick and muscular vessels that carry oxygen-rich blood away from the heart to the rest of the body.
Arteries have a higher pressure and lower volume than veins.
Normal ranges for blood volume vary depending on age, sex, weight, and health status, but generally range from 4 to 6 liters for adults.
