an erythrocyte, or red blood cell (approx. 5um). This forces the blood cells to pass through in single file, maximising oxygen diffusion efficiency.
***
Average diameter of an erythrocyte is 7.8 micrometer
Average calibre (diameter of the lumen) is 5-10 micrometer
This means that the diameter of an average erythrocyte is smaller than the calibre of the narrowest capillaries. Young erythrocytes can be deformed into any shape. The old lack such deformability, hence, their membrane rupture during their passage especially through splenic capillaries. Their lifetime is 120 days. If we are hopeless to need the old ones, then the spleen will be removed.

capillary
Approximately yes. Circumference is equal to pi times the diameter of the circle, which is 3.14159 times the diameter.
The circumference of a circle divided by its diameter is equal to pi which is an irrational number.
The diameter must be: 1
Circumference of a circle divided by pi is equal to the circle's diameter.

Vernier microscope radius of capillary tube
A human hair has an average diameter of 70 mikrometers and a capillary has an average diameter of 7 mikrometers, so that tells us that 1 hair takes about 10 capillaries in width.

The 'capillary effect'. See the link.
It is equal to a diameter of 10.5 units of length.
where the blood travels from the lungs to left the atria.^^^ This answer is wrong in every salient way. Use the Wikipedia entry here: http://en.wikipedia.org/wiki/Capillary
