    Red blood cells are about 120 days old, and white blood cells are not necessarily divided into different types.

    Human red blood cells are double-sided, concave round cakes. The edges are thicker and the middle is thinner, like a doughnut, except that there is not a hole in it. This shape maximizes oxygen uptake from the surrounding area.

    At the same time it is flexible, which allows it to pass through the capillaries and release oxygen molecules, usually 6 m 8 m in diameter.

    Due to this special shape and relatively small size, the ratio of surface area to volume is large, allowing oxygen and carbon dioxide to penetrate quickly inside and outside the cell. The cell membrane of red blood cells contains special polysaccharides and proteins, but this structure varies from person to person, and these structures are the basic elements of blood grouping.

    Decreased: all types of hemolytic anemia.

    An increase in the number of gauges can reduce the error relatively.

    The red blood cell count decreases by up to 10% between 5 p.m. and 7 a.m. and after meals, and bed rest can be reduced by up to 10% compared with normal activities.

    Red blood cell counts are highly susceptible to errors. Venous blood collection, tourniquet ligation for too long can cause false increase, unclean and inaccurate straws, which will increase the count or decrease the blue fluid; Suction of diluent is destroyed, and a manual dosing device is now used, and the capacity should be calibrated before use; The counting board should strive to purchase the accurate; Count enough quantities. If sufficient attention is taken, the results obtained by the manual method are still very accurate and can be used to calibrate the automatic counter.

    Answer]: c Hemolytic anemia is a type of anemia caused by the shortening of the survival of red blood cells for some reason, the increase in destruction and hunger, and the compensatory capacity of the bone marrow, iron deficiency anemia and megaloblastic anemia are anemias caused by the lack of hematopoietic substances, myelopathic anemia is anemia caused by the invasion of the bone marrow by abnormal tissues, and aplastic anemia is anemia caused by the abnormality of hematopoietic stem cells. The correct answer to this question is C.
