Answer:
Artery
Functions of vessels - Arteries transport blood away from the heart.
Structure of the wall - The wall of an artery consists of three layers. The innermost layer, the tunica intima (also called tunica interna), is simple squamous epithelium surrounded by a connective tissue basement membrane with elastic fibers. The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer.
Width of the lumen - lumen averaging 30 micrometers
Blood pressure - Blood pressure (BP), sometimes referred to as arterial blood pressure, is the pressure exerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs.
Types of blood - Arteries carry oxygenated blood away from the heart to the tissues
Are valves present- no
Capillar
Functions of vessels - Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart
structure of the wall - Capillary walls consist of a single layer of flattened endothelial cells, the endothelia, and these cells constitute the barrier between the blood.
Width of the lumen - The diameter of a capillary lumen ranges from 5–10 micrometers
blood pressure - blood enters the arteriole end of a capillary, it is still under pressure (about 35 torr) produced by the contraction of the ventricle
Types of blood - Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.
Veins
Functions of vessels - Veins return blood back toward the heart.
Structure of the wall - the walls of veins have three layers, or coats: an inner layer, or tunica intima; a middle layer, or tunica media; and an outer layer, or tunica adventitia. Each coat has a number of sublayers.
Width of the lumen- Veins are generally larger in diameter, carry more blood volume and have thinner walls in proportion to their lumen.
Blood pressure - Venous pressure is the vascular pressure in a vein or the atria of the heart
Type of blood - Veins are a type of blood vessel that return deoxygenated blood from your organs back to your heart.
