Which term means blood flow through the body tissues?

• A. Tissue perfusion
• B. Plasma
• C. Shock
• D. Hypertension

Answer: (A)

Tissue perfusion is the movement of blood through the capillary networks of body tissues, delivering oxygen and nutrients and removing waste. It describes how well blood reaches cells to meet their metabolic needs, making it the term that captures blood flow through tissues. Plasma is the liquid component of blood, not the flow through tissues. Shock is a state of critically insufficient tissue perfusion and circulatory failure, rather than the normal process itself. Hypertension means high blood pressure, which can influence perfusion dynamics but isn’t the term for blood flow through tissues. Adequate tissue perfusion depends on cardiac output, vascular resistance, and the oxygen-carrying capacity of the blood.
