Know Your Heart

 

The Heart is a key organ of the body that pumps oxygen and nutrient-rich blood throughout the body to sustain life. This fist-sized powerhouse beats 100,000 times per day. Heart isn’t only our most critical muscle-it’s what keeps us alive-but also one of the hardest working. It ticks 24x7 and except for the times when you’re relaxing or sleeping, it rarely gets a break. Below, find enthralling detail about heart that might aware to be away from risks.

Your body’s most important muscle needs your attention.

Do you know How it Works?

The heart has two sides – left and right, separated by a muscular wall.
There is an upper and lower chamber on each side connected by valves that direct the flow of blood.
The smaller upper chambers are known as the atria and the larger lower chambers are the ventricles.
The pumping of the heart is controlled by special fibres that conduct electrical signals to the various chambers.
The right side of the heart pumps the blood to the lungs, where it receives oxygen.
Blood enters the left side of the heart from the lungs and the heart pumps the oxygen-rich blood around the body.
Coronary Arteries

Coronary arteries supply the heart muscle with blood. The left and right coronary arteries divide many times to spread over the heart muscle wall and give it blood and oxygen. The coronary arteries get blood from the aorta, the major artery taking blood to the rest of the body. 

Coronary Heart Disease

Coronary heart disease affects many people. It’s a chronic condition – that means it is long term. Coronary heart disease happens when plaque builds up in your arteries. This makes them narrower and this process is called atherosclerosis. It can start when you are young and be well advanced by middle age.

Stable plaque is generally not harmful but if the arteries narrow too much it can cause angina. Unstable plaque has more fat, a thin cap and is inflamed. If an artery becomes too narrow, less blood can reach to heart muscle. This may lead to symptoms such as angina.

If a blood clot forms in a narrow artery and blocks the blood supply to part of a heart, it can cause a heart attack. While atherosclerosis develops slowly over decades, the major consequences can appear to be sudden.

Some people may not know they have coronary heart disease until they have a heart attack.
