What Are Veins?
Veins are another type of important blood vessel present inside the body. But they don’t originate from the heart of the human body. They start to originate from the body’s organs & then move towards the heart. The capillaries are the originating area of the veins in the body. From the small capillaries, small venules are produced. They are the branches of the veins. When the venules started becoming the full-sized vein, they come close to the skin. It carries deoxygenated blood from the organ to the heart. As there is no muscular layer present, the veins need to depend upon the valves for pumping blood.
Difference Between Arteries And Veins
Arteries and Veins are the two most important blood vessels present in the human body. There are nearly about 70 thousand miles long network present which is built up with the help of the arteries and veins. These blood vessels are small tube-like structures. Blood runs through these muscular tubes, commonly known as blood vessels. Blood is transported through arteries from the heart to the rest of the body. Blood is returned to the heart by veins. The human body is connected by a complex system of arteries and veins.
