MICROANATOMY

Detailed explanation-1: -Also known as erythrocytes, RBCs are the most common type of cell found in the blood, with each cubic millimeter of blood containing 4-6 million cells. With a diameter of only 6 µm, RBCs are small enough to squeeze through the smallest blood vessels.

Detailed explanation-2: -Nucleated red blood cells in mammals consist of two forms: normoblasts, which are normal erythropoietic precursors to mature red blood cells, and megaloblasts, which are abnormally large precursors that occur in megaloblastic anemias.

Detailed explanation-3: -Blood consists of 45% red blood cells, less than 1% white blood cells and platelets, and 55% plasma.

Detailed explanation-4: -Men: 4.7 to 6.1 million red blood cells per microliter of blood. Women: 4.2 to 5.4 million red blood cells per microliter of blood. Children: 4.0 to 5.5 million red blood cells per microliter of blood.

Detailed explanation-5: -Red blood cells (erythrocytes) carry oxygen to all cells in the body. White blood cells (leukocytes) are an important part of the. Platelets (thrombocytes) make the blood clot and help stop bleeding.
