The Oval Office exerts tremendous gravitational pull on its occupants. President Obama, in a fingers-crossed wish, has already predicted that the tug of the office eventually will move Trump into a more conventional orbit. Not so far.
Red blood cells are also known as erythrocytes. The red blood cells transport oxygen through the circulatory system to the cells and tissues of the body. In the cells, oxygen and glucose support glycolysis, the production of ATP (adenosine triphosphate). The red blood cells are filled with hemoglobin, the oxygen-carrying part of the red blood cell. Hemoglobin can also be spelled âhaemoglobin.â Each red blood cell contains 250 to 300 million molecules of hemoglobin. A molecule of hemoglobin is made up of one globin protein, with four iron-containing heme groups.
Red blood cells are structurally and functionally specialized to transport oxygen from the lungs to other tissues. Their cytoplasm contains the 33% solution of oxygen-binding protein hemoglobin the O2 carrying protein that account for their acidophilia.About 1/3 of the erythrocyte mass is hemoglobin.he primary function of blood is to supply oxygen and nutrients as well as constitutional elements to tissues and to remove waste products. Blood also enables hormones and other substances to be transported between tissues and organs.
