The heart its diseases and functions essay

According to the heart definition, you can call it a muscular pump which contracts at regular intervals in order to squeeze the blood through it into the blood vessels.

As you can see in the human heart diagram, there are four chambers in this tireless pumping organ. All the chambers work in coordination for the successful execution of different heart functions. The right chambers contain unclean or the deoxygenated blood.

On the other hand, the left chambers contain clean or the oxygenated blood. Just look at the different parts of heart to get a better understanding of the heart functions. Talking of the heart structure, it is made up of connective tissue and cardiac muscles.

The latter is a type of involuntary muscle, that is, it contracts and relaxes on its own without requiring you to deliberately apply force. Your heart is a delicate organ. Any damage to it will cause disturbance in the heart functions.

So, it gets protection from the rib cage.

Concerning shape, it looks like a cone. The base of this cone is positioned upward which gradually tapers down to the apex. The pumping organ is roughly the size of a wrist, while measuring 12 cm, 8 cm and 6 cm along length, width and thickness, respectively.

The effect of exercise on the muscles of the heart organ is the same as shown by the skeletal muscles. That is, as an outcome of exercise, they grow both in size and strength. That is why, the well-trained athletes usually have much larger hearts.

Such a thing also makes the heart functions better.

The knowledge about heart function and structure is important for those who want to maintain and enjoy cardiac health. The heart functions involve the supply of oxygenated blood to all parts of the body.

The circulatory system consists of three main types of blood vessels: Arteries carry oxygenated blood and distribute it to different parts of the body. On the other hand, the veins receive unclean blood, containing carbon dioxide and waste products, from the body parts and take it back to the heart.

A heart attack is distinct from cardiac arrest, which is a sudden loss of heart function that usually occurs as a result of electrical disturbances of the heart rhythm. The heart is supplied with arterial blood by the right and left coronary arteries. On the contrary, its deoxygenated blood or the venous return is by the coronary sinus which empties into the right atrium. Functions: The function of the heart is to maintain a constant circulation of blood throughout the body. The organ of the cardiovascular system is the heart and the system also has arteries veins, and capillaries which are the blood vessels. The main tissues that are in the cardiovascular system are the epithelial tissue, muscle tissue, nervous tissue, and connective tissue.

The heart contains both the oxygenated and deoxygenated blood. It is its job to keep both of them separate in order to avoid contamination of the pure blood. The right chambers of the heart receive blood, devoid of oxygen, from the veins.

This blood then goes to the lungs to receive oxygen and get rid of carbon dioxide. Afterwards, this oxygen-rich blood goes back to the heart from where it reaches all the body parts through the arteries.

In this way, every individual cell is able to get oxygen. This oxygen will assist in the process of extracting energy from food. In order to understand how the heart works, it is important to know about its main parts. There are four chambers in the heart; the top chambers are atria while the chambers below them are ventricles.

As many as four valves control the flow of blood into and out of the heart. A double-walled membrane, the pericardium, separates the right and left chambers, preventing oxygen-rich blood from mixing up with the one without oxygen. So, the heart functions go smoothly.The human heart is an organ that pumps blood throughout the body via the circulatory system.

Urinary System: Facts, Functions & Diseases; Parts of the human body. Bladder: Facts, Function. The Heart And Its Function. The heart is considered as the body's circulatory pump, located in the thoracic cavity.

It is made up of four chambers, two upper chambers known as Atria and two lower, thicker walled chambers, known as Ventricles.
