Answer:
Precapillary sphincters are the type of smooth muscles that adjust the flow of blood through the capillaries. These are the muscles, which help to regulate the blood flow when required.
It helps in conservation of heat, as when the hypothalamus of the brain senses that the temperature of the body is too high it sends a signal to dilate the blood vessels, which leads to a reduction in the flow of blood to body tissues, As a result of that less heat is lost.
Precapillary sphincter muscles aid in heat conservation.Because when the hypothalamus of the brain detects that the body's temperature is too high, it sends a signal to dilate blood vessels.
What is a precapillary sphincter?
Smooth muscles are called precapillary sphincters to regulate the flow of blood via capillaries. These are the muscles that help to control blood flow when it is needed.
It aids in heat conservation because when the hypothalamus of the brain detects that the body's temperature is too high, it sends a signal to dilate blood vessels, resulting in a reduction in blood flow to body tissues and hence reduced heat loss.
