Modified capillaries that are lined with phagocytes are called ________.

Question

Quizplus · Accepted Answer

Sinusoids are modified capillaries found in organs such as the liver, spleen, and bone marrow. They have gaps between the endothelial cells that line them, which allows for the passage of large molecules and cells. They are also lined with phagocytes, which are specialized cells that can engulf and break down foreign particles and debris. Therefore, B is the best choice as it specifically mentions capillaries lined with phagocytes. Fenestrations (A) are also openings in capillaries, but they do not necessarily refer to capillaries with phagocytes. Thoroughfare channels (C) are a type of vessel that connect arterioles directly to venules and bypass capillaries. Anastomoses (D) are connections between two blood vessels, but do not specifically refer to modified capillaries with phagocytes.
