The blood flow in milliliters/ minute during exercise to the skin is:
Correct answer: D. 1900 ml
- A. 1500 ml
- B. 1600 ml
- C. 1800 ml
- D. 1900 ml
Explanation
Skin blood flow plays a major role in the distribution of thermal energy during exercise. When we exercise, our body temperature increases and carries the blood toward the skin's surface, causing us to sweat and cool off. This natural body mechanism can lead to a flushed, red face, which can be especially more noticeable in fair-skinned individuals. The blood flow to the skin during exercise is 1900 ml/min. orMore oxygen is required by the cells as the rate of respiration increases, thus the blood flow to the skin increases as well.REFERENCE: KPK BIOLOGY BOOK

About Blood Vessels
Blood vessels include arteries, arterioles, capillaries, venules and veins, whose wall thickness, elasticity, lumen size and valves suit their roles in circulation. Questions compare pressure and blood flow in each vessel and distinguish pulmonary vessels, which carry blood to and from the lungs, from systemic vessels.
