??? Identify the capillary A B C
A B Capillary
??? Identify the Artery A B C
A artery C
??? Identify the Vein A B C
vein B C
??? 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 A B C Why is it so important for the capillary (C) to be so thin?
??? 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 A B C Why is it so important for the walls of vessel B to be so thick?
