Q

What is double circulation?

A

Blood goes through twice on every circulation

17
Q

What are the characteristics of the arteries?

A

Thick, muscular, elastic wall. Narrow lumen.
They must cope with high pressures of blood, because it has just come from the ventricle

18
Q

What are the characteristics of the veins?

A

one-way valve so that blood flows in one direction only. Thin wall, thin muscles, larger lumen

19
Q

What are the characteristics of the capillaries?

A

Very thin to allow as much oxygen to diffuse as possible. Blood plasma passes through capillary walls
