Veterinary Gross Anatomy-II

PULMONARY VEINS

• The pulmonary veins are usually 4 to 7 in number and are devoid of valves.
• The capillaries arise from plexus around the alveoli of the lungs, unite to form larger branches accompanying the arterial branches on the ventral face of the bronchioles and finally form the pulmonary veins which open into the left atrium.
