The function of the venule includes the exchange between blood and tissue and the transport of blood as part of the vascular system. … Venole
Difference between a venule and an arteriole An arteriole is also a component of the final flow path of the vascular system and resembles an artery in its wall structure. The arteries generally have a larger and more compact muscle layer than the veins. The arterioles form the resistance vessels in the body’s circulation and … Difference between a venule and an arteriole | Venole
