The textbook truth is that the only obvious function of mature red cells in the body's economy is to transport oxygen (why it is advantageous to have haemoglobin within a membrane-bounded space rather than in free solution must not concern us here). Yet, necessarily, there is a red-cell ...
All blood cells (red cells, white cells and platelets) develop from haematopoietic (literally meaning "blood-making") stem cells, located in the bone marrow. It has recently been found that manyplatelets are made in the lungs, from megakaryocytes that have migrated there from the bone marrow....

As an inherited disorder commonly found in individuals of African descent, sickle cell anemia affects red blood cells, making them abnormally sickle-shaped, which results in a blockage of blood flow. Learn more about sickle cell anemia, including the affected locations of the body and the signs,...
What do purple hands mean? Cyanosisrefers to a bluish cast to the skin and mucous membranes. Peripheral cyanosis is when there is a bluish discoloration to your hands or feet. It's usually caused by low oxygen levels in the red blood cells or problems getting oxygenated blood to your body...
