Q
Red Blood Cell
A
cells that transport oxygen through the bloodstream and do not contain a nucleus
3
Q
Volume
A
the amount of space inside an object. Measured in (units of length)3 (i.e. mm3, cm3, m3)
4
Q
Surface area
A
the sum of the area of all exposed sides of a three-dimensional shape. Measured in (units of length)2 (i.e. mm2, cm2, m2)
5
Q
Ratio
A
a comparison between two things to show proportions
6
Q
surface area : volume ratio (SA:V)
A
a comparison of the amount of surface area per unit of volume. In Biology, SA:V influences temperature regulation, and a high SA:V leads to more effective transport into and out of cells
