Understanding Red and White Blood Cells Functions Structure Biology Diagrams Blood is a connective tissue whose matrix is fluid. It is composed of: red corpuscles, white cells, platelets, and blood plasma. It is transported throughout the body within blood vessels, which is the subject of Section 8 of this atlas. Red Blood Cells. Red blood cells are also known as erythrocytes or red blood corpuscles.
The middle white layer is composed of white blood cells (WBCs) and platelets, and the bottom red layer is the red blood cells (RBCs). These bottom two layers of cells form about 40% of the blood. Plasma is mainly water, but it also contains many important substances such as proteins (albumin, clotting factors, antibodies, enzymes, and hormones

Red cell senescence is the result of a conformational change in a membrane protein, band 3, leading to the appearance of a senescence-specific antigen recognized by autologous immunoglobulin (Ig) G, marking the cells for removal by macrophages. 1 In addition, aged red cells are also more susceptible to oxidant stress and therefore to eryptosis.
Blood is a fluid tissue that flows through arteries, veins and capillaries in the human body. Components of blood include red blood cells, white blood cells, platelets and plasma. There are several differences between red blood cells and white blood cells in structure, function and appearance.

There are more red blood cells in your body than white blood cells. How are white blood cells formed? White blood cell formation occurs in the soft tissue inside of your bones (bone marrow). Two types of white blood cells (lymphocytes) grow in the thymus gland and lymph nodes and spleen .
The erythrocyte, commonly known as a red blood cell (or RBC), is by far the most common formed element: A single drop of blood contains millions of erythrocytes and only thousands of leukocytes (Figure 18.3.1).Specifically, males have about 5.4 million erythrocytes per microliter (ยตL) of blood, and females have approximately 4.8 million per ยตL.In fact, erythrocytes are estimated to make up
