Red blood cells are by far the most abundant cells in the blood. There are an average of 2,830,000 RBCs per cubic millimeter (microliter). RBCs account for approximately 40 to 45 percent of the blood. This percentage of blood made up of RBCs is a frequently measured number and is called the hematocrit. The ratio of cells in normal blood is 600 RBCs for each white blood cell and 40 platelets.

Place leukocytes in order from the most common to the least common?
Leukocytes, or white blood cells, are typically ordered by abundance in the following way: neutrophils are the most common, followed by lymphocytes, monocytes, eosinophils, and finally basophils, which are the least common. This hierarchy reflects their relative prevalence in the bloodstream and their roles in the immune system. Neutrophils are primarily involved in fighting bacterial infections, while lymphocytes play key roles in adaptive immunity.
