The Circulatory System consists of Heart and Blood Vessels

Types of Blood Vessels:

The circulatory system consists of blood vessels that are of two types

1. Arteries
2. Veins

Generally, blood vessels are described as arterial which refers to the arteries that carry the blood away from the heart, or venous which refers to the veins through which the blood seeps and goes back towards the heart to get oxygenated and for repumping.

A large artery such as the aorta branches into smaller arteries and these eventually divide further into the smallest blood vessels known as capillaries. These capillaries open into other capillaries which are the starting point for the return of blood to the heart.

The microscopic capillaries form a capillary bed, at the transition zone where arterial blood becomes venous blood. The returning blood moves from the capillaries to the small veins known as venules and unites to form larger veins that return back to the heart.

List of Arteries:

• Common Carotid artery
• Subclavian artery
• Axillary artery
