Red blood cells contain enormous amounts of a protein called hemoglobin. Transport oxygen from the lungs to the cells of the body. Secrete anticoagulants and antibodies that have function against hypersensitivity reactions in the bloodstream. Red blood cells also transport waste such as carbon dioxide back to our lungs to be exhaled. Secrete heparin which is an anticoagulant that promotes mobility of other WBCs by preventing clotting. Red blood cells serve as the vehicle to rid your body of this waste. All these components play very important roles in the body, however, in this article we will only focus on the function of red blood cells. The second important function, just as important as carrying oxygen although less commonly known, is the ability of red blood cells to carry carbon dioxide. Red blood cells have adapted this characteristic (no nucleus) for several reasons. Red blood cells (RBCs), also known as erythrocytes, have two main functions: Blood cells. While the RBCs play a major role in eliminating carbon dioxide from the cells, blood plasma also accounts for a small amount of carbon dioxide removal. In women, hemoglobin < 12 g/dL (120 g/L), hematocrit < 37% (< 0.37), or RBC < 4 million/mcL (< 4 10 12/L) is considered anemia.
