If all the blood was to rush from your hart but not out of your body, Would your hart still beat?

This is a complex question involving many components in a heartbeat. Firstly, I'll assume that your question means the chambers of the heart is empty, but not the coronary vessels supplying the heart to keep the heart muscle alive. (Or else the heart muscles would just die and the heart stops.)\n\nA heartbeat is stimulated by several factors, and those related to your question are blood pressure and blood volume.\nIn the situation where all the blood rush out of the heart, the blood pressure would remain nearly unchanged as the slight increase in blood volume is not significant. However, blood volume is partly detected by receptors in the heart itself (if the heart stretch more, blood volume is higher) Now that the heart is empty, it would tend to slow down its beating and wait for blood to fill it before it beat again.\nThe effect is gradual, so theoretically, the heart would beat slower and slower until it stops.\n\nHowever in reality, it is impossible for the heart to become empty without the heart dying as the coronary arteries and veins are attached directly into the heart.

nope, just a sweatier tummy. It can actually be bad for you, as it could cut off blood flow.

you would probably suffocate from the high altitute b-cuz there isnt much oxygen up there.

maybe if you were a hummingbird or some other creature.... like insects I think have heartbeats even faster than that... but I don't think a person could ever reach that.

He killed your deer? that's terrible....\n\na "hart" is a deer.......that organ in your chest is a "heart", sweetie.  just so you know.

I would guess No...\n\nThis is because once your dead, your tissues, muscles, nerves , and organs aren't functioning.\n\nThis could be true if it were a couple seconds after his death... because it would be closely remniscent to a story where someones head got chopped off, andd he could see his own body from the ground. And that is a true stroy since your nerves in your head continue to funmction for a couple of seconds more...\n\n~LG23~

blood rushes to it and makes it bigger...

You would die! Duh...\n\nTerry

Gravity!  the heart works harder to pump blood when you are standing!

In some muscular organs yes. For example, I remember that once I tied a cat's legs together (don't blame me! I was only 5!) I wanted to untie him soon but mummy called me and I forget it until I heard his meow (it took about half an hour). I rapidly untied him but for 3 minutes or more he was not able to walk OK and walked like drunk people!\n\nBut, many mammals have organs which could be still for a long time without getting asleep. In fact, the mechanism of blood circulation in those part is so that the motionlessness of that organ does not affect it. Maybe they have special one-way ports in their veins which may prevent blood blockage. Or have some bypass paths which guarantees the full coverage of blood transfer even if a local blockage occurs. In other types of animals (except than birds), I don't think that such phenomenon could be seen because of the nature of their blood circulation system.

well, depends, i have a heart condition and i cant get heart attacks from a simple scare, my heart might beat faster and harder, but thats for everyone else.  I do know someone who if you do scare him, he would have to be rushed to a hospital because his heart would almost fail.  So yes and no, only under the circumstances.

He would beat you, Chuck.\n;-)

I would think it would be just about impossible even if you ran water through the veins there should still be a few blood cells

Yes conceivably but your body would decide to breathe in spite of your wishes once if you are unconscious. The only thing that would stop that was if something was blocking your air passages.

Well that couldn't happen. Our blood has to have oxygen mixed with it in order for blood to serve its purpose. Without it, there would be no platelets in our blood, therefore no defense mechanism to viruses and bacteria. We'd die of a simple common cold in hours. In addition, without oxygen, our brain cells would die and we would be a complete "vegetable" in about 2 hours.\n\nIf you are talking about putting the biologic stuff aside and assuming out biological bodies didn't need oxygen, then we'd be able to sleep with the fishes. We wouldn't need a heart anymore, because the purpose of the heart is to take unoxidated blood and mix it with oxygen that we breathe in, then pump it through out our bodies. In addition, we could travel through space without worrying about oxygen

The blood does rush to my head and even though i have been here for all 16 years of my life it does get uncomfortable sometimes (or that could just be a migrane). I did try to aleviate this pain a little while back and lied down with my head pointing up, but all the blood went away from my head and I blacked out. I have since decided to keep the blood in my head so that inconveniences like that don't happen again.

No. You'd fall through it. It's just water molecules. It sounds cool though!
