Blood Cells Lesson 41
Our bright red blood contains seven types of cells, such as: I. Red blood cells. II. White blood cells or leukocytes. III. Thrombocytes or platelets (clotting cells). We will see importance of each type of cell one by one now. I. Red blood cells or Erythrocytes: These cells are made in the bone marrow (soft tissue in the center of certain bones) and are necessary to carry oxygen from the lungs through the blood to all body cells. The oxygen is then used up by body cells in the process of converting food to energy (catabolism). Hemoglobin (globin is a protein) is an important protein in erythrocytes that carries the oxygen through the bloodstream. II. White Blood Cells or Leukocytes: Leukocytes are of two types. a). Granulocytes b). Agranulocytes Granulocyes- Granulocytes-these cells containing dark-staining granules in their cytoplasm, and these cells are formed in bone marrow. They are further divided into three types of cells such as A). Eosinophils-these ce...
