One of the most important muscles in the body of the organism and especially the human body is the heart muscle. The heart muscle or heart of the most important parts of the body is the vital pulse of human life, and the loss of the soul from the heart is the loss of the soul of the body completely leading to the death of the organism.
Definition of heart
The heart is the organ that pumps blood from the heart to all parts of the body. The heart is composed of arteries and veins, divided into two main stones: the ventricle (the right ventricle and the left ventricle) and the atria (right atrium and left atrium) Parts of the body’s cells, and then return the blood loaded with carbon dioxide, and the carbon dioxide is replaced by oxygen, and then the blood is injected again for all parts of the body, it is worth mentioning that the heart muscle is also a muscle grow and grow with human growth and progress in age The size changes with the introduction Age.
Definition of heart beat
We mentioned how the heart works to pump blood to all parts of the body, but how long it takes the blood to get out of the heart loaded with oxygen, and back to the heart with carbon dioxide. This process is a contraction and myocardial infarction, which acts as a pump working on the contraction and extinction. The sphincter or the accuracy of the heart represents the so-called contraction and relaxation of the heart muscle in the blood pump in the blood circulation on which all the cells of the body parts, blood reaches all parts of the body. We note that there is a specific index of heart rate, the rate of heart beats or normal heart rate, which represents the proportion of the number of heart beats per minute.
Number of natural heart beats
The normal heart rate ranges from 70 to 80 strokes, and the heart rate ranges from 60 to 100 beats per minute, a normal percentage of blood that takes the blood out and back to the heart during circulation.
Factors that affect the number of heart rate
Age or age
Heart rate is affected by the age of the human heart of the small child reaches the number of heartbeat natural to 90 pulses, because of the size of his body is small, the length of the blood circulation is very small, and fit with small size, blood comes out and return to and from the heart in a very short time. A person with a heart rate ranges from 60 to 100 beats. In the old age, the pulse is between 70 and 80 beats.
Physical activity
When the body is exercising or doing physical activities, it takes extra effort to reverse the effort in a relaxed state. Where the heart rate increases per minute above 100 beats, usually up to 150 beats, but soon return the heart rate to normal position after the completion of this extraordinary effort to the normal state of the body.
Sudden feeling of fear and others
When a person is exposed to a certain situation that causes sudden fear, the rate of adrenalin produced by the heart in the body increases. This leads to an increase in the number of sudden heart beats from the normal range, and usually these situations cause heart attacks; because of uncontrolled number of heart beats beyond the normal limit, and also affect the incidence of anemia on the number of heartbeat, it is worth noting that the activity of the thyroid gland and It is called a heart battery that also affects the control of the number of heart beats.
Heart rate measurement
It is recommended to measure the heart rate in a state of rest and relaxation or after waking from sleep, that is, the blood circulation in normal and normal condition and there is nothing affecting them, and can measure the heart rate by placing the fingers of the hand under the position of the ear at the end of the temple face, The veins in the hands where the heart beats and beats when measured, and also advised in the case of an increase in the number of heart beat to 100 beats when not doing any activity that affects the natural heartbeat. It is advisable to visit the doctor and consult him to detect this situation, which has a high heart rate, as well as in the case of low heart rate without 60 pulse also visit the doctor to check on health; the most important thing in the health of the human body is the health of the heart.
