The heart is one of the most important organs of our body. It pumps blood throughout the body at all times, so that all the organs get enough oxygen and nutrients to function optimally. That is, the heart can be called the monitor of the whole body, however, unfortunately in the last few decades, due to disturbances in lifestyle and diet, the risk of many diseases related to this organ has increased.
Earlier, where heart diseases were known to be a problem with aging, now even younger people are falling prey to it.
You must be hearing and watching news and information related to heart diseases every day, but do you know about your heart? How does it work, how does it pump blood? Or what conditions can increase the risk of heart disease?
Let us understand all these in detail today.
How our heart works
Our heart beats continuously, from 60 to 100 times per minute in a healthy person. As the heart beats, it pumps blood through a system of blood vessels called the circulatory system. This blood reaches every part of the body through the elastic vessels attached to the heart.
The oxygen received from the lungs also goes to the rest of the body along with this blood. This process is necessary to keep the organs and tissues of the body healthy, any obstruction in it can affect the entire body.
The heart gets nourishment from the coronary arteries
Your heart, like all other parts of the body, is also made up of tissues that require a supply of oxygen and nutrients. Although its chambers are filled with blood, the heart does not get any nutrition from this blood. Coronary arteries help supply nutrients to the heart. These arteries and their branches supply blood to the heart muscle.
In some conditions, when the coronary arteries become narrow, which limits the flow of blood to the heart muscle, it can lead to the risk of coronary artery disease.
What is heart disease?
When it comes to heart disease, the term refers to a variety of heart-related problems. The most common type of heart disease in the United States is coronary artery disease (CAD), which affects the flow of blood to the heart. Decreased blood flow can lead to a heart attack. Our bad lifestyle habits, diet, and lack of exercise all directly affect the health of the heart.
Knowing these things also
According to the American Heart Association, our heart beats (expands and contracts) about a million times a day, pumping 5 to 6 liters of blood every minute, which is about 2,000 gallons a day. This process continues even when we are sleeping. Smoking – Due to physical inactivity, the risk of diseases related to this organ is increasing considerably, so it is necessary to stay away from them.
