White blood cells are larger than red ones by a few times
red blood cells are disc shaped while white blood cells have no permanent shape.
White blood cells use phagocytosis to remove foreign particles from the blood stream. These cells will literally engulf foreign particles that are the same size as itself. There are two types of white blood cells which act as phagocytes: macrophages and polymorphic leucocytes. To be phagocytosed, particles need to bind to the receptors on the phagocyte. Then the particle is engulfed and absorbed.
White blood cells are the largest of the blood cells but also the fewest. There are only 5000 to 10,000 white blood cells per microliter. There are several different types of white cells but all are related to immunity and fighting infection. On average there are 50 microliters in one drop of blood. There are 250,000 to 500,000 white blood cells per drop of blood.
The lumen is the size of the inside of the blood vessel. The type of blood vessel that has a lumen approximately the same diameter as a single red blood cell is a capillary.
The number of blood cells in animals varies depending on the species and size of the animal. In general, mammals have billions to trillions of blood cells. Humans, for example, are estimated to have around 20-30 trillion red blood cells and about 2-3 trillion white blood cells in their bodies.

15 micrometers
While they are very similar in size white blood cells are bigger while red bloods cells are much more numerous.
RBC - 7-8um WBC - 10-12um.

White blood cells have a variety of different spacial features. They are two types, granulated and agranulted. They can vary in size from about 7 microns for a lymphocyte to 21 microns for a phagocyte.
In a male your size, or in fact, most adults, the average of the amount of blood is 5 liters, or 5,000ml.

White blood cells are larger. White blood cells range in size from 7-21 micrometers in diameter. Red blood cells are typically 6-8 micrometers in diameter. However, RBCs are more prevalent, accounting for 25% of the volume of blood, whereas WBC's only account for 1%.
The lumen is the size of the inside of the blood vessel. The type of blood vessel that has a lumen approximately the same diameter as a single red blood cell is a capillary.
No, they don't. There are over 200 different types of cells in a human body. All have different functions and different sizes and shapes. But, each type is of the same size in every human. For example, the muscle cells would be of the same size in all the humans. the red blood cells are different from the muscle cells in terms of their function and their size and shape; however, all human will have the same size of red blood cells. Hope that helped..
