Blood Volume
Blood volume refers to the total amount of blood present in the circulatory system of an individual. In the context of space and astronautical engineering, blood volume is an important physiological parameter that is affected by microgravity. During spaceflight, the body experiences a shift of fluids from the lower extremities to the upper body, resulting in a decrease in blood volume. This decrease in blood volume can lead to cardiovascular deconditioning, orthostatic intolerance, and other physiological changes that can impact astronaut health. Therefore, monitoring and maintaining blood volume is crucial for the health and safety of astronauts during space missions.
