VAN 121: Veterinary Gross Anatomy-II (2+2)

VENOUS SYSTEM

• The veins are the centripetal vessels of the circulatory system. The veins may be divided in to superficial and deep.
• The superficial veins of the body form an extensive network, lie immediately under the skin and are mostly unassociated with the arteries.
• The deep veins are placed deeply and are accompanied by the arteries.
• The anastomoses formed by the vessels of the venous system are larger, more frequent and complicated than those of the arterial system.
• Numerous such anastomoses give raise to the formation of the venous plexuses.
• Most of the veins are the satellites of the arteries and need no special description.
• Therefore, only few important venous distributions, which under go independent courses, will be discussed here.
