Which term describes supplying blood through blood vessels through tissues?

• A. Perfusion
• B. Permeability
• C. Petechiae
• D. Phlebitis

Answer: (A)

Perfusion is the process of delivering blood through the circulatory system to the capillary beds in tissues, enabling oxygen and nutrients to reach cells and wastes to be carried away. This is exactly what is meant by supplying blood through blood vessels to tissues. Permeability, in contrast, refers to how easily substances pass through vessel walls and into surrounding tissue, not the overall delivery of blood to tissues. Petechiae are tiny spots caused by bleeding under the skin, a sign of leakage, not the flow of blood to tissues. Phlebitis is inflammation of a vein, which can affect venous function but does not describe the act of perfusing tissues with blood.
