Explanation:

Question 100

Vascular anastomoses are connections between blood vessels (veins to veins, arteries to arteries) that bypass capillary networks. Coronary arteries supply the heart, venous sinuses are large venous cavities, and venous valves prevent backflow in veins. So the correct answer is vascular anastomoses.

Lacteals are lymph capillaries in the small intestine that absorb dietary fats. The spleen, liver, and thymus have other lymph - related functions but no lacteals.

The thymus is the primary lymphatic organ as it is where T - lymphocytes mature. The thalamus is part of the nervous system, the thyroid is an endocrine gland, and the spleen is a secondary lymphatic organ.

Answer:

A. vascular anastomoses
