Why is it so important for the capillary (C) to be
so thin?
A
B
C
Oxygen and glucose can pass easily from the blood in the
capillary, through the capillary walls, to the cells—and waste can
travel in the opposite direction from cells, through capillary
walls, into the blood

(C) to be so thin?
C
???
Why is it so important for the walls of vessel B
to be so thick?
A
B
C
The inside layer is smooth so blood can flow freely,
middle layer muscle, outer layer flexible: arteries need
to be able to withstand enormous pressure of blood as
it is pumped by the heart, must expand and relax
between heartbeats
