Anatomy of the Heart and Cardiovascular System: All that You Need to Know

The heart is one of the most incredible and powerful organs inside the human body. It does a lot of work every single second to keep us alive and to keep our bodies going. Your heart does a whole lot more physical work than any other muscle in your body over a lifetime. 

In a nutshell, your heart is a muscular pump that stimulates blood circulation to every tissue inside your body. If the human heart stops functioning or loses its ability to pump blood even for a few minutes, it can cause some severe damage to the individual’s body. 

Today, we will learn about the anatomy of the human heart, the cardiovascular system, and its functioning. Read on!

The Human Heart Anatomy: A Detailed Analysis

The human heart is almost the size of a big fist, and it weighs around 8-10 ounces in women and 10-12 ounces in men. Placed in the middle of the chest between the lungs, the heart leans slightly towards the left side of your body. 

The average adult heart pumps over 5 liters of blood every minute throughout their life. And it beats roughly about 100,000 times in a day and about 3 billion times in a lifetime! The heart pumps blood and pushes it to every cell, tissue, and organ in the body. 

This blood then delivers oxygen and other vital nutrients to every cell and removes carbon dioxide and other waste materials generated by those cells. The blood is carried from the heart to all parts of your body via a closed and complex network of arteries, capillaries, and arterioles. And it is returned to your heart through veins and venules. This whole procedure is essential for your organs to stay alive and work properly.

The human heart comprises four chambers: two upper chambers, known as left and right atrium, and two bottom chambers, known as the left and right ventricles. The right atrium and right ventricle form the “right heart,” and the left atrium, along with the left ventricle, makes up the “left heart.” A muscular wall known as the septum separates these two sides of the heart.

The Anatomy of the Cardiovascular System

The heart, together with arteries, capillaries, and veins, forms the cardiovascular system. It is also known as the blood-vascular system or just the circulatory system. The cardiovascular system is primarily responsible for the transportation of oxygen, nutrients, hormones, and cellular waste products to and from different organs of the body. It is powered by the heart, which pumps blood throughout the body. 

The oxygen-rich blood is carried away from the heart and to other parts of the body through arteries. At the same time, the oxygen-poor blood is transported back to the heart from other organs through veins. 

There are two kinds of circulatory loops that take place inside the human body: 

  1. The pulmonary circulation loop
  2. The systemic circulation loop

In the pulmonary circulation loop, the deoxygenated blood gets transported from the right side of the heart to the lungs. The blood picks oxygen from there and returns to the left side of the heart. The right atrium and right ventricle support the pulmonary circulation loop.

On the other hand, the systemic circulation loop carries the oxygenated blood from the left side of the heart to all cells, tissues, and organs of the body. The only exceptions are the heart and the lungs. This circulation loop also removes the waste products from body tissues and carries deoxygenated or oxygen-poor blood to the right side of the heart. The left atrium and left ventricle support it. 

Summary

So, that was a brief overview of the anatomy of the heart and the cardiovascular system. 

When the heart or the cardiovascular system doesn’t function properly (heart failure, arterial stiffness, irregular heartbeats, etc.), doctors often rely on medical devices to assist them.
