Detailed explanation-1: -A low RBC count in the body can lead to anemia which can affect the body’s ability to carry and supply oxygen to the tissues. A low WBC count can lead to leukopenia that can hamper the immune system of the body. A high RBC count is produced in the body during exercise or at high altitudes.

Detailed explanation-2: -White blood cells are not part of the circulatory system. White blood cells, although they are found in the blood plasma, are part of the immune system. The main function of the immune system is to remove the body of pathogens and keep us healthy.

Detailed explanation-3: -Blood contains far fewer WBCs than red blood cells, although the body can increase WBC production to fight infection.

Detailed explanation-4: -The number of WBCs (WBC count) is lower than the number of RBCs; however, the WBCs are larger in size RBCs. There are 5 types of WBCs; each type plays a different role in protecting the body from invaders.

Detailed explanation-5: -Red blood cell (RBC) count: 3.93 to 5.69 million cells per cubic millimeter (million/mm3) Hemoglobin (Hgb, Hb): 12.6 to 17.5 grams per deciliter (g/dL) for males; 12.0 to 16 g/dL for females. Hematocrit (HCT): 38% to 47.7% White blood cell (WBC) count: 3, 300 to 8, 700 cells per cubic millimeter (thousand/mm3)
