How your heart works is likened to the engine of an automobile. Human hearts are the most vital organ of the human body. Hearts are the engine of the human body. How your heart works is emphatically like the engine of a car. If it stops or malfunctions, it is always hard if not completely impossible to restore. Without the motor engine of course, nothing works. This is likened to the hearts. If the heart stops functioning, it usually leads to instant death. The function of other parts of the human body is centered on the heart as it is the distributor or rather the circulate of blood.
How your Heart Works
The overall weight of blood pumped out regularly by the heart is estimated at ten tons and the impulse used for the heart beat comes from the muscle. The rate at which the heart beats is controlled by two sets of nerve fibers – the accelerator and the inhibitor nerves. The rate varies in different persons and it is in response to some demands of the organism at different times. In male, the rate of heart beat is much higher than in female. This heart beat rate in men may be as high as 150 during vigorous body exercise and as low as 60 during sleep. Following each heart beat, hearts have a period of rest. This relaxation period is shorter during vigorous activities and longer when the body is inactive.
How your Heart Works During Exercise
It is wrong to think that participating in vigorous body exercise places a heavy demand upon the heart muscle that it eventually becomes enlarged. The fact is that such vigorous body activity does increase the work of the human heart. During this process, enlargement also appear, but these changes are normal and required. That’s exactly how your heart works.
