Physiological Changes


Physiological changes refer to alterations in the normal functioning of the human body due to exposure to the space environment. These changes can occur in various systems of the body, including the cardiovascular, musculoskeletal, and immune systems. In microgravity, the body experiences a shift in fluid distribution, leading to a decrease in blood volume and changes in blood pressure. The musculoskeletal system also undergoes changes, including muscle atrophy and bone loss. The immune system is also affected, leading to a decrease in immune function and an increased risk of infection. These physiological changes can have significant implications for the health and safety of astronauts during space missions.
