MICROANATOMY

Detailed explanation-1: -Erythrocytes, or red blood cells, are the most numerous of the formed elements. Erythrocytes are tiny biconcave disks, thin in the middle and thicker around the periphery.

Detailed explanation-2: -Red Blood Cells (also called erythrocytes or RBCs) Known for their bright red color, red cells are the most abundant cell in the blood, accounting for about 40 to 45 percent of its volume.

Detailed explanation-3: -The formed elements include erythrocytes and leukocytes, which are cells (although mature erythrocytes do not have a nucleus); however, the formed elements also include platelets, which are not true cells but cell fragments.

Detailed explanation-4: -Red Blood Cells (RBCs or erythrocytes) make up more than 95% of the formed elements.

Detailed explanation-5: -RBCs make up 99.9% of blood’s formed elements – develop in myeloid stem cells when erythropoietin (EPO) is secreted by kidneys in response to low oxygen levels in blood.
