  1. Comparison chart Physical features Life span Types Circulatory system Total count RBC 700:1 WBC Functions Presence in blood Components Production Movement Significance of irregularity in count Nuclei Shape RBC RBCs are bi-concave disc shaped, and have no nucleus. size is roughly approximately 6-8 gm 120 days. There is only one type of RBCs found in the blood. Cardiovascular system males 4.6 million - 6.2 million per cubic mm females 4.2 million-5.4 million per cubic mm Supplies oxygen to different parts of the body and carries carbon dioxide and other waste products. Makes up 36-50% of our blood depending on sex, height & weight Hemoglobin Produced in red bone marrow. they move in blood vessels eventually squeezing through capillaries giving 02 and nutrients to body cells. A very low RBC count will result in anemia. RBC do not have nuclei in humans Biconcave disc WBC WBCs are irregular in shape, but have a nucleus and an outer buffer coat. 4-30 days depending on body There are various types of WBCs with distinct functions in the blood:neutrophils, T lymphocytes, B lymphocytes (plasma cell) monocytes (macrophage), eosinophils, basophils. Cardiovascular and lymphatic systems. 4000 - 11000 per cubic mm Producing antibodies to develop immunity against infections. Some are phagocytic Close to 1% of the blood. Antibodies with MHC antigen cell markers. Produced in lymph nodes, spleen, etc. they leave the blood vessels and move to the injury site. Capable of diapedesis-squeeze between cells of blood vessel walls to exit circulation. The WBC count goes up significantly when there is any infection present. WBC have nuclei in humans Have different kinds of shapes and don't
