Trouble, thanks!

Anonymous users2024-02-04Red blood cells are the most important component of blood. It accounts for about 50% of the total blood volume. So, when these red blood cells are suspended in the plasma, the blood becomes red.
Red blood cells, also known as red blood cells, do not have a nucleus and have no formed structures within the cytoplasm. The whole is a concave oblate disc-shaped, with a diameter of about microns. This double-sided concave disc shape is unique to red blood cells and allows them to increase their surface area more efficiently and carry as much oxygen as possible.
The number of red blood cells per cubic millimeter (i.e., 1 microliter) of blood in China is 4,005,500,000 for adult men, 3,500,500 for adult women, and more than 6 million for newborns. People who live on plateaus for a long time are more likely than those who live at sea level; People have more red blood cells, and a person is more active than when they are quiet.
There are two kinds of red blood cells in the blood, one is fully mature, called mature red blood cells; The other is near-fully mature, called reticulocytes. Reticulocytes are slightly larger in diameter than mature erythrocytes and can reach 8-9 mm. A normal person has one reticulocyte for every 100 red blood cells in their blood.

Anonymous users2024-02-03Red blood cells are one of the components of blood, in 1 cubic millimeter of blood, there are about 4 million red blood cells, and the red color of blood comes from red blood cells, to be precise, from the color of hemoglobin in red blood cells.
For men, 1 liter of blood contains between 4 and for women. For newborns, in the first week of life, the content of red blood cells in the body can be as high, this is because the newborn in the fetal period is dependent on the placenta for oxygen, need a lot of red blood cells to transport oxygen, after birth, the newborn breathes spontaneously, can directly get rich oxygen from the air, no longer need too many red blood cells, so too many red blood cells will be destroyed.
