BLOOD VASCULAR SYSTEM

• This system consists of a series of arteries that carry blood into all parts of the body.
• They divide into smaller arterioles, which in turn divide on entering the tissues into minute microscopic tubes, the capillaries.
• The venous capillaries originate from the arterial capillaries and are interposed between the arterial capillaries and the beginning of the veins.
• The veins in turn carry impure blood to the heart.
