Composition of blood. The blood is composed of cells, cell fragments and an aqueous solution (plasma). Blood makes up about 8% of the human body weight. It contains erythrocytes, leucocytes, thrombocytes (platelets) and plasma.The volume percentage of all blood cells in the whole blood is about 45% in adults (hematocrit).he acid-base homeostasis is regulated in the blood: Through the diffusion of gases between alveoli and blood in the lung (alveolar diffusion) oxygen diffuses from the alveoli into the blood due to the concentration gradient. It is taken up by the carrying protein hemoglobin (hem = iron-containing, globin = protein).
Components of blood Blood is the medium in which all the cells are carried to transport nutrients and oxygen to the cells of the body. Blood is made up of four components. These are red blood cells, white blood cells, platelets and plasma. Blood is made up of 55% plasma and 45% solids. Red blood cells 99% of red blood cells are red blood cells or erythrocytes. They are red in colour due to the prescience of a red coloured protein called haemoglobin.
