Fluid Compartments, Hemocirculation and Erythrocyte Function in Monkeys After Spaceflight (B11-28)
Principal Investigator
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Macaca mulatta Species: Monkey Strain: Rhesus


Study of the fluid compartments of the body can give insight into the structure and function of organs and tissues, as well as their microcirculation. Evidence indicates that interstitial fluid, circulating blood volumes, and arterial and venous capacity remain constant under normal conditions. What happens to these parameters in microgravity? This experiment measured the volumes of fluid compartments and circulating blood before and after microgravity exposure. The results may help to gain an insight into the changes seen in different muscle types during spaceflight.
