The worn femoral head and acetabulum (the ball and socket respectively) are removed and replaced with [...]

The Search for a Blood Substitute

2019-01-10T12:17:20-08:00 November 2nd, 2002|Health & Medicine, Issue I, Volume V|

In recent years, America's blood shortage has propelled the biotechnology of blood substitutes. Artificial blood does not contain the plasma, red and white cells, or platelets of human blood, but functions to transport and deliver oxygen to the body's tissues until the recipient's bone marrow has regenerated the missing red blood cells. Current blood substitutes [...]
