heart valves opening and closing
it stops pumping obviously come on guys lets get with the program
The sound coming from your heart is the sound of the valves in the heart closing and the turbulence in the blood that results. In a normal healthy adult the first sound (or lub) is from the closing of the AV valve and the second sound (or dub) is from the closing of the semilunar valve.
It doesn't unless there are internal injuries. If there is internal bleeding, especially in the lungs, the blood may come out of the mouth.
The function of heart pumping is to make blood to flow through the circulatory system, so that the body cells get their nourishment and keep you alive. During your entire life, the power generated by the billions of heartbeats, is enough to send you to the moon and come back.
The sound of a heart beat is caused by the closing of the valves in the heart.
An artificial heart is made from metal and plastic, and has a small pumping chamber lined by a special material that stops blood clots forming. An artificial heart that provides an extra ventricle to help pump blood around your body.
your heart!your attiliries carry blood from the heart and your veins carry blood to your heart because they ran out of "food"
yes if i doesnt come out ull die
No. The heart is an organ that pumps blood.
You have things called arteries that carry the blood full of oxygen throughout your body. Right below your jaw you can feel your pulse. This is one of your arteries pumping blood to your brain. Once the blood has used up all of its oxygen, it is pumped back to your heart through your veins to receive more oxygen.
The heart has two pumps inside of it and each has two chambers and two valves. The left side of the heart has the biggest chambers, and the one that pumps the blood to your body is called the left ventricle, When it contracts (squeezes together), the first valve closes shut (that's the "lupp" sound of a heart beat) and the contraction pushes the blood up past the second valve and into aorta, which is the main artery that distributes the blood to the regular arteries that carry the blood throughout the body. When the blood goes into the aorta, the second valve shuts so the blood doesn't go backwards into the heart and that is the "dubb" sound of a heart beat.
this is two step process.in the first process blood go from the heart and in the second step blood come into the heart for clean. when it goes from the heart it is cleaned blood,but when it returns it become dirty and our heart performs as a filter and it cleans our blood. this is the chemistry of blood, hopefully you would like it.
