Which term refers to the body's ability to deliver adequate blood to tissues?

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

Answer: (A)

Tissue perfusion is the body's ability to deliver adequate blood to tissues, providing oxygen and nutrients while removing wastes. This delivery depends on sufficient cardiac output, proper arterial pressure, and open microcirculation so blood can reach all cells that need it. When perfusion is adequate, tissues stay well nourished and functioning; when it’s insufficient, cells become ischemic and organ function can deteriorate. Plasma is the liquid component of blood that carries nutrients, hormones, and waste products, but it isn’t the process of delivering blood to tissues. Shock is a state where tissue perfusion is critically reduced, leading to organ dysfunction. Hypertension is high arterial pressure, which affects blood pressure levels but doesn’t define how well tissues are being perfused.
