The heart is a vital organ. It is essentially a muscle which helps in distribution and circulation of blood to the entire body. It consists of arteries, veins, and capillaries which are the vessels which distribute the blood all over the body. The heart is divided into four parts. The two which are placed on the top are known as the left and right atria while the other two chambers are known as the right and left ventricles. The above mentioned chambers are the origins of where blood vessels lead in and out from essentially.
Mechanism of blood circulation
The right and left side chambers of the heart work in conjunction. Essentially the right side chambers pumps blood into the lungs whereas the left side chambers pumps the blood into the tissues and the organs of the entire body.
The right side of the heart gives entry to deoxygenated blood though the superior and inferior vena cava which helps it to flow into the right atrium. Eventually after passing the tricuspid valve and right ventricle, the blood is pumped into the lungs by the pulmonary valve. The lungs remove the carbon dioxide from the blood and oxygenate it.
On the other hand the left side of the heart , with the help of the pulmonary vein takes the oxygen rich blood to the left atrium and then into the left ventricle from the lungs. Lastly, the aortic valve transports it to the aorta, which is the blood vessel that sends the oxygen rich blood to all the organs of the body. This cycle must take place to sustain the life of a human being.
Mechanism of the heart beat
The ventricles and the atria work in conjunction by relaxing and contraction on an alternative basis to pump blood in one’s heart. Electrical impulses are created which triggers the heartbeat that travels through a unique pathway in the heart
On an overall basis, a healthy heart is one which keeps the body full of fresh blood, nutrients hence its effective functioning is important for ones healthy living.
