The active hyperemia is the consequence of dilation of arterioles and the resultant influx of blood in the capillaries, which occurs during blushing or excercise.
<u>Explanation:</u>
The rise in organ blood circulation correlated with an organ or tissue having elevated metabolic activity is understood as active hyperemia. An illustration of active hyperemia is the rise in blood flow that follows muscle contraction, also named skeletal muscle activity or responsive hyperemia.
It typically occurs when blood is needed by the organs more than normal. Your blood vessels are expanding to improve blood running in. Reactive hyperemia is the blood circulation reaction to occlusion of blood flow, while active hyperemia is the blood flow result of increased metabolic activity of the tissue.
The answer to that question is organic compound. Organic compound is the compound that is defined as any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. Organic compounds are also vital when it comes to life processes which take place in all organisms.
