Answer 1

Answer:

Explanation:

Red blood cells, also called erythrocytes, are the most abundant cell type in the blood. Other major blood components include plasma, white blood cells, and platelets. The primary function of red blood cells is to transport oxygen to body cells and deliver carbon dioxide to the lungs.

Red blood cells are also important in determining human blood type. Blood type is determined by the presence or absence of certain identifiers on the surface of red blood cells. These identifiers, also called antigens, help the body's immune system to recognize its own red blood cell type.

Structure of RBC

The shape of a red blood cell is a biconcave disk, it has a sunken centre on both sides, this allows the cell to have a larger cell membrane surface which can be exposed to diffusing oxygen while it is travelling to the lungs.

The structure also enables the cells to be more flexible when it comes to them passing through tight passages like the capillaries. This is because they are flexible, bendy and bounce about, the cells are around 7.8 micrometers in diameter.

The immature red blood cell contains a nucleus but the mature ones don't, they also don't have mitochondria or other organelles. However, the red blood cells do contain hemoglobin, these are molecules of protein and iron.
