Veins The veins carry deoxygenated blood from the body tissues and organs to the right atrium of the heart.
Feature of the vein •
Larger, thinner , the capacity is grater paired valves ; • Two sets Sup. one of veins Deep one follows an a. • Aboundant anastomoses • Special forms inclouding diploic vein and sinus of dura mater .
