What is the Role of the Cardiovascular System?

Your body’s cardiovascular system ensures it gets the oxygen, nutrients, and other necessities it needs and gets rid of the ones it doesn’t. Even when you are asleep, your heart circulates blood throughout your body. Your healthcare team provider can hear your heartbeat. Your heart is making magic in your body by making this sound. Your heart pumps about 2,000 liters of blood per day. Veins transmit blood from your heart to certain blood vessels, whereas arteries move blood away from your heart.. 

Two Vital Circulation Processes

Pulmonary Circulation: Blood without oxygen enters the right side of your heart. It is then sent to the lungs for oxygenation and carbon dioxide removal. The oxygenated blood then flows back through your left side.

Systemic Circulation: Blood that has just received oxygen from your lungs and is returning through the left side of the heart is pushed out to all your cells for oxygen and nutrients. When blood is devoid of oxygen, the cycle begins all over again.


What Does the Cardiovascular System Look Like Structurally?

Your cardiovascular system is very important because your heart powers the system that gives your cells what they need and removes what they don’t. Your heart is connected to a network of blood vessels throughout your body.

Sewer or water lines may be visible beneath the street. These lines join to progressively smaller pipes that bring water into your home and remove sewage. The blood veins that enter and exit your heart are the largest in your body, comparable to the enormous pipes under the street.

What size is your cardiovascular system? The size of your heart is approximately the same as your fist. The blood vessels that run through your body are as long as your arms. What is the weight of your heart? Your heart weight can be affected by gender, body weight, and disease. It’s thought to range from 8 to 12 ounces. What makes up the cardiovascular system? The blood vessels comprise connective tissue, muscle, and elastic fibers. Muscles and other tissue make up the heart. It has four hollow chambers that allow blood to flow. Learn more in a&p class
