What are the properties of arteries ?
Arteries are the vessels that carry blood in the heart to other organs.
Arteries carry oxygen-rich blood (clean blood). The pulmonary artery, on the other hand, takes the dirty blood (excess CO2 concentration blood) into the lung to clear.
Arteries are named according to the organ from which they deliver blood. (For example, the vein that delivers blood to the lung is called the lung artery.)
Arteries consist of three layers from outside to inside.
a. Outer layer: It is made of fibrous connective tissue and ensures the vascular resistance against blood pressure.
b. Middle layer: Consists of smooth muscles. The elastic fibers in this layer facilitate the movement of the blood with the flexibility it gives to the vessels.
a. Inner (endothelial) layer: It consists of a single-layer flat epithelial tissue. The endothelium creates a slippery surface that allows the blood to move easily.
