A
hemostasis
B
hematopoeisis
C
hematocrit
D
hemoglobin
Explanation: 

Detailed explanation-1: -The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). The normal hematocrit for men is 40 to 54%; for women it is 36 to 48%.

Detailed explanation-2: -Hematocrit is the percentage of red cells in your blood. Normal levels of hematocrit for men range from 41% to 50%. Normal level for women is 36% to 48%.

Detailed explanation-3: -The ratio of hematocrit (Hct) to hemoglobin (Hb) has been generally accepted to be 2.941 for long time[1], and it is simplified to be 3.0 in the daily clinical practice. This figure can be applied for the people who have normal red blood cell (RBC) morphology.

Detailed explanation-4: -Hematocrit is a measure of the portion of blood occupied by cells (red blood cells, white blood cells and platelets). A hematocrit of 0.40 L/L (litre of cells per litre of blood) indicates that 40% of the blood volume is composed of cells, with plasma making up the other 60%.

Detailed explanation-5: -Men: Blood Volume = (0.3669 × H^3) + (0.03219 × W) + 0.6041. Women: Blood Volume = (0.3561 × H^3) + (0.03308 × W) +0.1833.
