Answers
Explanation:
The three types of blood vessels are:
Arteries
Arteries are the main blood vessels that carry and transport oxygenated blood or oxygen-rich blood from the heart to other parts of the body. They are the strongest blood vessels with thicker walls and are muscular in nature. It consists of three distinct layers, which are rigid, thicker and highly muscular. Arteries are located deep within the body and are red in colour. These blood vessels are with high pressure and move in a downward direction from the heart to the body tissues.
Veins
Veins are thin, tube-like elastic blood vessels, present closer to the surface of the skin. These translucent blood vessels are blue in colour and carry impure or deoxygenated blood from all parts of the body to heart. These blood vessels are with low pressure and move in an upward direction, i.e. from the cells, tissues and other organs to the heart. Compared to the arteries, veins are thin-walled.
Capillaries
Short and tiny blood vessels, found within the tissues are called capillaries. Capillaries bring about the exchange of substances between blood and tissues. These blood vessels also function by connecting arterial systems to the venous system and help in exchange of substances across cells.
Layers of Blood Vessels
Both arteries and veins consist of three layers.
Tunica Intima: It is the innermost and thinnest layer of arteries and veins, which have a direct contact with the blood flow.
Tunica Media: It is the middle layer of an artery or vein, which is made up of smooth-muscle cells.
Tunica Externa: It is present adjacent to the tunica media and is composed of collagen and functions by supporting the elastic lamina in arteries.
