What makes the heart to beat?

Answer 1

The heart beats to pump oxygenated blood to musles and organs throughout your body to keep them functioning and "to stay alive". The heart also receives blood that has already travelled throughout your body and pumps it through the lungs to re-oxygenate the blood.

The "beat" of the heart is created by the opening an closing of valves within the heart.

Answer 2

The heart muscle beats independently of any stimulus, however autonomic nervous stimulation EXAMPLE: the vagues nerve can override the basic contraction rate (around 40-60bpm) to control the force and rate of contraction.

Answer 3

You heart beating lets you know you are still alive. The heart pumps blood throughout your body. When it stops working, so do you (without external intervention).

The regular beating of the heart beat maintained by electrical impulses form the heart pacemaker, which is located in the wall of the right atrium.

Answer 4

Heart beats are basically the sound of closing of bicuspid and tricuspid valve during auricle systole ventrical systole and also during dystole of these valves The total time for heart cycle is 0.8sec

Answer 5

Your heart is sort of like a pump, or two pumps in one. The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body. Before each beat, your heart fills with blood. Then its muscle contracts to squirt the blood along. When the heart contracts, it squeezes - try squeezing your hand into a fist. That's sort of like what your heart does so it can squirt out the blood. Your heart does this all day and all night, all the time.

Answer 6

The heart pumps blood around the body because it carries oxygen and glucose to the brain, without them a person will loose consciousness. Muscles need oxygen, glucose, amino acids, sodium, calcium and potassium salts in order to contract normally, these are all carried through the blood in our bodies from the foods we eat and the air we breathe.

Without blood circulating the body, it begins to shut down and after a very short period of time will die.

Answer 7

If oxygenated blood from the lungs to the heart is not pumped to the rest of the body, by the heart, then tissues will die from lack of oxygen (and other nutrients transported in the bloodstream). Blood needs to reach all tissues and cells, and can only do so if it propelled to them by a pressure gradient (the pressure being highest in the large arteries, and gradually less until reaching the capillaries, where the pressure is very very low).

Answer 8

the heart is a pump its only job is pump blood throw the body...

ALSO: the heart needs to pump so that blood can go through your body and keep you alive

Answer 9

The human heart beats to pump blood throughout the body.
