Erythrocytes, Leukocytes, Thrombocytes
Blood cells consist of:
Erythrocytes or red blood cells represent the largest or the most portion that is as much as 99%. The shape of red blood cells is biconcave, flat, round, concave in the middle and piled.
The functions of erythrocytes or red blood cells are: determining blood type and transporting oxygen carried by hemoglobin.
Hemoglobin carrying oxygen also causes blood red or called oxyhemoglobin.
b. Leukocytes (white blood cells)
White blood cells are bulkier than red blood cells. Forms of white blood cells are lymphocytes, basophils, neutrophils, monocytes, and eosinophil.
The function of leukocytes or white blood cells is to kill germs in the body and to form antibodies. Which kill germs is Phagocyte by eating them. Antibodies are produced by lymphocyte that is antitoxin which serves to neutralize toxins produced by germs.
c. Thrombocytes (platelets)
Thrombocytes or platelets formation is in red marrow, the number of platelets in 1 mm3 is 25,000 platelets. Platelet function is to help blood clotting. How is the process of blood clotting? In case of injury of the body, platelets directly will produce an enzyme called Thrombokinase; it will change prothrombin to thrombin. Furthermore, thrombin will convert fibrinogen or blood protein into fibrin threads, fibrin threads shaped nets that will catch red blood cells out due to injury, by the arrest of red blood cells by nets or fibrin, blood will clot and stop flowing.
