the red blood cells will dilate meaning just like your eyes dilate your red blood cells will get bigger to get more oxygen to muscles and tissues. as when you run for long periods you will notice your face becoming more red which is a result in vasodilation simply red blood cells but larger.. this also triggers the sweat glands to sweat and then evaporate on your skin to cool down the skin.

When vasodilation occurs, the blood vessels in the affected area expand, allowing for increased blood flow. This leads to increased supply of oxygen and nutrients to the tissues. Additionally, vasodilation helps in removing waste products and heat from the area, contributing to overall improved circulation.

What happens when blood vessles dilate?
Vasodilation or dilation of the blood vessels is due to a decrease in vascular resistance. As a result of the dilation of blood vessels, blood flow increases. Mammals or warm blooded creatures use vasodilation to move warm blood closer to the surface of the skin where heat can be released. Vasodilation serves as a form of cooling in warm blooded animals.
Why does vasodilation and vasoconstriction happen in a cycle?
Vasodilation and vasoconstriction occur in a cycle to regulate blood flow and maintain homeostasis in the body. Vasodilation refers to the widening of blood vessels, which allows for increased blood flow and delivery of oxygen and nutrients to tissues. Vasoconstriction, on the other hand, is the narrowing of blood vessels, which reduces blood flow and conserves heat and nutrients. These processes are dynamically regulated based on various factors such as tissue oxygen levels, metabolic demands, and body temperature.
Explain the term Vasodilation and Vasoconstriction. how do these process contribute in temperature-regulationof the body?
Vasodilation refers to the widening of blood vessels, increasing blood flow and heat loss through the skin, which helps to cool down the body during hot conditions. Vasoconstriction, on the other hand, is the narrowing of blood vessels, reducing blood flow and heat loss through the skin, which helps to retain heat and warm up the body during cold conditions. These processes play a crucial role in temperature regulation by adjusting blood flow to the skin to maintain a stable core body temperature.
What happens when blood doesn't flow to an organ?
The Organ dies
How do you increase blood flow?
Blood flow can be increased in two main ways: firstly, the heart can pump blood round the body at a faster rate i.e. by increasing blood flow. Secondly, vasodilation can take place, by which blood vessels "expand" in order to allow more blood to pass through. This process is mainly used during exercise, when our body needs to lose excess heat energy.
What occurs when lungs receive normal airflow and reduced blood flow?
Alveolar 02 concentrations rise and results in vasodilation of the pulmonary vessels to increase blood flow to match the airflow.
What decreases peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
What increases blood flow in capillaries the most?
arteriole vasodilation

What is the act of vasodilation?
The act of vasodilation is the widening of blood vessels when the walls of blood vessels relax. The purpose is to increase blood flow to areas of the body that are in need of oxygen.
What would decreased peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
Will Vasodilation result in increased blood flow to a given tissue?
yes
Why do men get erections after eating a big meal?
they just completed the hunt and its time to eat
Is the exercise vasodilation?
Yes. As you exercise, the vessels of blood in the muscles dilate and thus the blood flow greatly.
Will eating beets lower blood pressure?
I am not completely sure about beets lowering blood pressure, but beets do increase vasodilation. When this happens your arteries open up allowing for more blood to flow to the rest of your body.
What is the rationale with acute inflammation with warmth and fever?
An acute inflammation with warmth and fever occurs for two reasons. The fever is the result of the release of pyrogens from white blood cells. Warmth is due to vasodilation and a decrease in blood flow.
What happens when clot occurs in an undamaged blood vessel?
The flow of blood to tissues beyond the clot may be cut off
