Introduction:
Arteries are the resistance vessels that give oxygenated blood to the organs. Arteries are known for their strong and resilient tissues that can withstand the pressure created by the heart. They are more muscular in nature than veins are and able to maintain their round shape even when the vessels are empty. The veins carry de-oxygenated blood from the organs to the heart. They are also called as capacitance vessels, as they have a flaccid and thin wall. When compared to arteries, they accommodate 64% more volume of blood than that of arteries with only 13% of the blood. The veins have low blood pressure than arteries and have a steady blood flow. Unlike arteries, some veins are equipped with valves that ensure one way flow of the blood. When empty, the veins collapse and get flattened and form an irregular shape in the histological sections.
