Heart structure and function

What exactly is the heart?

The heart is a fascinating organ that is our... Keeps life in rhythm in the truest sense of the word. But how exactly does this vital organ work and how is it structured? Today we will explain the structure and function of the heart, so that you are guaranteed to understand what is pumping inside us.

The heart is an amazingly complex organ made up of different parts, each of which plays an important role in our body. Although science and medicine have been dealing with the "blood pump" of humans for a very long time, research continues to provide new, fascinating findings. Today, however, we take a first look at the basics of the heart and its important components Features.

The structure of the heart

The heart is a hollow muscular organ and

about the size of your closed fist. Of course, the actual size varies from person to person. It consists of two halves – the left and right halves of the heart. These halves are separated by a thick muscular wall, the cardiac septum. The right side of the heart collects deoxygenated blood from the body and pumps it to the lungs, where it is enriched with oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the rest of the body so that all organs and tissues are supplied with oxygen.

The structure of the heart is much more complex than it seems at first glance. Other important parts of it are the heart valves. Our heart has four valves that work like doors and ensure that blood flows in the right direction. This Valves are the aortic valve, the pulmonary valve, the mitral valve and the tricuspid valve. Since the heart is a very muscular organ, and like any muscle, it requires oxygen and nutrients to function properly, quite a lot happens in this red organ every second. Oxygen and nutrients become provided by coronary arteries, which surround the heart and provide it with the necessary resources.

Furthermore, the heart of esurrounded in a special membrane, the pericardium or pericardium. This protects the heart from external influences and prevents friction when the heart beats. The last most important part of the heart is the Heart wall to call. This consists of three layers: the endocardium (the inner layer that covers the heart valves), the myocardium (the middle layer that allows the heart to contract) and the epicardium (the outer layer that supports the heart surrounds).

The function of the heart

The most important thing to remember about the heart and its functions in our body is that Heart works like a pump. With each heartbeat, the muscles contract to move blood forward. This process repeats itself constantly, and the heart beats about 70 to 80 times per minute in an average adult.

It is equally important to know that there are two main phases in the cardiac cycle: the Contraction (systole) and the Relaxation (diastole). During systole, the heart muscles contract and pump blood from the heart chambers into the large blood vessels. During diastole, the heart relaxes to prepare for the next beat and to accept blood from the atria.

That's why the heart is so important

The heart is a central part of our cardiovascular system. This system ensures that blood, oxygen and nutrients are transported to all of our organs and tissues. Without a functioning heart, our body would not be able to survive. So always take care of our most important organ and eat healthily. Because various diseases that come from poor nutrition can also be dangerous to the heart.

The heart, as we have learned, is an amazing organ that keeps our bodies alive. It consists of two halves that pump oxygen-depleted and oxygen-rich blood and works like a pump, moving blood throughout the body. The cardiovascular system ensures that our body is well supplied with everything it needs. And that's why it's important to keep our heart healthy by eating a balanced diet and regular exercise regard. By understanding how our heart is built and functions, we can better take care of our health and live long, fulfilling lives.
