Question
Name the process involved in the maintenance of constant body temperature that causes an increased blood flow to the capillaries close to the surface of the skin by increasing the diameter of the arterioles that supply them.
Solution
The process involved in the maintenance of constant body temperature that causes an increased blood flow to the capillaries close to the surface of the skin by increasing the diameter of the arterioles that supply them is called Vasodilation.
Here are the steps involved in this process:
-
The body detects a rise in internal temperature through thermoreceptors located in the hypothalamus and the skin.
-
The hypothalamus, which acts as the body's thermostat, responds by sending signals to the smooth muscles in the walls of arterioles in the skin.
-
These signals cause the smooth muscles to relax, resulting in the widening or dilation of the arterioles, a process known as vasodilation.
-
Vasodilation increases the amount of blood flowing through the capillaries in the skin.
-
The increased blood flow brings more heat to the surface of the skin, where it can be lost to the environment.
-
This helps to lower the body's internal temperature and maintain it within a safe range.
