What are the main functions of the cardiovascular system during exercise?.

Answers

The main functions of the cardiovascular system during exercise are: Hear rate, breathing rate, blood, vessels and capillaries.

What is cardiovascular system?

All of the body's cells receive nutrition and oxygen through the cardiovascular system, which circulates blood. It is made up of the blood veins that run throughout the body and the heart. Blood is transported from the heart via the arteries and returned by the veins.

Heart rate: One important part of your cardiovascular system is your heart. Your pulse increases when you workout because your body needs more blood that is oxygenated.Breathing rate: As your lungs work harder to meet the increased demands for oxygen, your breathing rate rises. Through your mouth and nose, oxygen enters your lungs where it combines with blood to go throughout your body. Following the removal of oxygen from the blood and its entry into your active muscles and tissues, carbon dioxide, a waste product, is also expelled by the lungs.Blood: The blood is an essential component of your circulatory system because it delivers nutrients and other bodily fluids during exercise. Blood that has been infused with oxygen exits the heart and flows to the muscles you are doing out.Vessels: If our heart, lungs, and blood don't have a method to transfer oxygen and nutrients, they can't function properly. Your blood vessels, including your veins and arteries, are where this transit takes place. Your blood can move through your veins smoothly and quickly during exercise, especially if they are clear of blockages like cholesterol and fat. The blood arteries control the amount of blood that reaches each active muscle and organ.Capillaries : The capillaries pass the gases to and from the muscles, along with the nutrients needed to sustain your workout and prevent you from feeling fatigue.
