How does the human body function in zero gravity?

However our heart works perfectly in zero gravity but on earth the cardiovascular system circulates fluids through the body, working against gravity to prevent blood from pooling in the legs and bringing blood to the brain. read more

The sensation of weightlessness, or zero gravity, happens when the effects of gravity are not felt. Technically speaking, gravity does exist everywhere in the universe because it is defined as the force that attracts two bodies to each other. read more

To calculate the force of gravity, physicists use the formula f = ma (force = mass x acceleration). Circulatory System The excess gravity on the body will pull fluids down into limbs and causes the heart to work harder to get blood around the body. read more
