Hey We can't see anything because its very dark there. :)
The human heart is in the chest cavity.
The type of model you would use to represent your human heart would be a physical model.
Not if you're a human. The human heart has four chambers. If you are a reptile or an amphibian then yes, it would be normal to have three chambers in your heart.
If every human didn't have a heart, all humans would be dead except for animals. BTW, this is a stupid question.
Without a heart pumping blood throughout the body, a person would die.
Never... The heart of a pig would not function correctly in a human.
An internal organ if that's what you mean.
YES, of course it's important! The human body couldn't function right without a heart. That's how important it is. Without our heart, there would be no blood circulating althroughout our body.
yes because it is a human heart
about 1 watt
If you find your sternum (the center of your rib cage your heart is slightly tilted and just to the left of it
The heart can stop for many reasons - doctors would not transplant a damaged heart into a person so if the first person died from a heart attack, they would not use their heart. However, if something else caused the heart to stop beating and the heart is otherwise healthy, they will transplant it into the second person, who will not have that same problem that might cause the new heart to stop.
