Red Blood Cell = 8 micrometers Sperm Cell = 60x5 micrometers Skin Cell = 30 micrometers Egg Cell = 130 micrometers Information obtained from (where there's a dandy to-scale, zoomable picture): http://learn.genetics.Utah.edu/content/begin/cells/scale/
A red blood cell in human blood is about 6-8 µm in diameter. (µm is one 1000th of a millimeter)
So the average diameter of a normal human red blood cell would be about 7 thousandths of a millimeter wide.
In other words, 143 red blood cells together, laying flat, in a line, would measure about one millimeter end-to-end.
a red blood cell is the size of a pin point when magnified 100 times
Probably they have other blood groups. If I remember it right, there are 19 blood groups for dogs.

and a red blood cell or in a red blood cell? if its in a red blood cell i would say haemoglobin
The red blood cell, or more accurately, the hemoglobin molecule within the RBC
phagocytosis
It will undergo crenation. This means that the red blood cell will shrink in size and become shrivelled-looking. This is due to osmosis, which is the net movement of water molecules from a region of higher water potential (red blood cell) to a region of lower water potential (hypertonic solution) through a partially-permeable membrane (cell membrane).

the average size of a red blood cell is about 7.2 micrometers in diameter.
It is 8µm in size.
spleen
Red blood cell age can be determined by the size and shape of the cytoplasm and the nucleus or absence of nucleus.
They are 6-8 micrometres
A red blood cell when placed in salty solution shrinks and becomes wrinkled.
1000 red blood cells To 1 white blood cell
The size of a white blood cell is on average about 700 times smaller than a red blood cell. Source: http://library.thinkquest.org/25896/sub_blood/wbc.htm
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 white blood cell has nucleus that red blood cell does not
