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.

What name is given to a tube of very small diameter?
capillary
Is the circumference of a circle equal to 3 times it's diameter?
Approximately yes. Circumference is equal to pi times the diameter of the circle, which is 3.14159 times the diameter.
What is a irrational number equal to the circumference to the diameter of the circle?
The circumference of a circle divided by its diameter is equal to pi which is an irrational number.
What is diameter made of?
Circumference of a circle divided by pi is equal to the circle's diameter.
For the circumference of a circle to equal pi what must the diameter be?
The diameter must be: 1
