How Your Heart Works

How your heart works is simply likened to the engine of a motor. Human Hearts are the most vital organ of the body. Hearts are the engine of the body. How your heart works is emphatically like the engine of a car. If the engine 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 often leads to death.

The function of other parts of the human body is centered on the heart as it is the distributor or rather the circulator of blood.

How your heart works
The total weight of blood pumped out often by the heart is estimated at ten tons and the impulse used for the heart beat comes from the muscle. The rate of heart beat is controlled by 2 sets of nerve fibers - the accelerator and the inhibitor nerves. The rate varies in different people and in response to some demands of the organism at different times. In men, the rate of heart beat is much higher than in women. This rate of heart beat in men may be as high as 150 during vigorous body exercise and as low as 60 during sleep. Following each beat, hearts have a period of relaxation. This rest period is shorter during vigorous activities and longer when the body is not active.

How your heart works during exercise
It is incorrect to think that participating in vigorous 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 heart, and enlargement also appear, but both changes are normal and required.
