Webof their "anti-gravity" muscles and thus experience this natural atrophy. When astronauts return to earth, these muscles can still cause problems. Thus, in microgravity, tension is reduced on muscles that support the body against gravity, resulting in a loss of muscle mass and an accompanying loss of muscle strength. Web28 de set. de 2016 · Gravity redistributes blood pressure in the body. Humans blood pressure in orbit goes down in the limbs and up in the aorta; the head gets so much more blood that everyone has a puffy face. (See chap. 4.5 & 4.6.) Your high-gravity species need better ways to pump blood against gravity, low-gravity species need it less.
