Veins are larger than arteries therefore they?
Have more pressure
Have less pressure
which means spare blood is housed in veins that can be used in case of blood loss (this is also called?)
(a)
Veins participate in?

if body is too hot, blood is shunted from deep veins to superficial to release heat from the body
