The increase in blood flow is designed to remove what from the local area?

• A. Excess heat
• B. Metabolic wastes
• C. Carbon dioxide
• D. Toxins

Answer: (A)

When a local area warms up, the blood vessels dilate and increase blood flow. This brings more warm blood to the surface where heat can be lost to the environment. The carrying away of excess heat from the tissue is the primary purpose of this response, aided by heat loss mechanisms at the skin such as convection, radiation, and, if sweating occurs, evaporation. While blood can transport other substances like carbon dioxide or metabolic wastes, their removal is not the main goal of increasing local blood flow for heat dissipation.
