  • Hemolysis inside the body can be caused by a large number of medical conditions, including some parasites (e.g. (wikipedia.org)
  • We previously believed it was caused by gravity not pushing blood to the same spots in the body. (yahoo.com)
  • Hemolysis is when the body isn't producing the number of red blood cells it needs. (yahoo.com)
  • They believe that this will allow the body to process more energy, and thus create more red blood cells. (yahoo.com)
  • Healthy red blood cells usually live about 120 days (4 months) in the bloodstream before the body removes them. (daviddarling.info)
