True. In mammals, an increase in the temperature of the preoptic area of the hypothalamus activates physiological mechanisms for heat dissipation including vasodilation.
<h3>What is
vasodilation?</h3>
Vasodilation, as it is known in medicine, occurs when blood vessels in your body open up, enabling more blood to flow through them and resulting in a reduction in blood pressure. Without your knowledge, your body goes through a routine procedure like this. It can also be brought on by the foods and beverages you consume as well as the drugs you take. Vasodilation may also be a sign of a particular illness.
The two of the many functions that your blood serves in the body:
- Carrying oxygen and nutrients
- Aiding in temperature regulation in your body.
Your body's blood arteries are more complex than simple tubes that remain constant in size. Your blood arteries include muscle as well, and that muscle regulates how wide or narrow they are at any particular time. Vasodilation occurs when blood vessels enlarge. Vasoconstriction is the opposite process, which occurs when blood vessels narrow and contract.
