Description

This animation explains the effect of Martian gravity on the human body. Mars' gravity is only 38 percent that of Earth's, because the Red Planet is smaller and less dense. Reduced gravity causes organs to float instead of sit on the organs below them. On Earth a person's blood pressure gradually increases from the head to the feet. Reduced gravity makes blood pressure uniform throughout the body, causing more blood to flow to the head and tricking the body into determining that there is too much blood in the body. Reduced gravity also causes bone and muscle to atrophy.
