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).
Blood consist of cellular material (99% red blood cells, with white blood cells and platelets making up the remainder), water, amino acids, proteins, carbohydrates, lipids, hormones, vitamins, electrolytes, dissolved gases, and cellular wastes.Each red blood cell is about 1/3 hemoglobin, by volume.he straw-colored liquid portion, called plasma, forms at the top (~55%). A thin cream-colored layer, called the buffy coat, forms below the plasma. The buffy coat consists of white blood cells and platelets. The red blood cells form the heavy bottom portion of the separated mixture (~45%).
