Different types of blood vessels vary slightly in their structures, but they share the same general features. Arteries and arterioles have thicker walls than veins and venules because they are closer to the heart and receive blood that is surging at a far greater pressure (Figure 2). Each typ...

Blood vessels running all through the lungs carry blood to each air sac, or alveolus (肺泡), and then back again to the heart. Only the thin wall of the air sac and the thin wall of a capillary (毛细管) are between the air and the blood. So oxygen easily diffuses from the air ...
Blood vessels are of three types: arteries, capillaries, and veins. Arteries transport blood away from the heart. They have think walls composed of an inner endothelium layer (tunica internal), an outer connective tissue layer (tunica external), and also a thick middle layer (tunica media) of...

Functions of the Blood Vessels Arteries carry oxygenated and nutrient-rich blood to the body’s tissues from the heart. Dilatation and constriction of the arteries can alter blood pressure and cardiac output. Veins carry deoxygenated blood and wastes from the tissues to the liver and heart. The ...
blood pressure directly, and it is a main strategy for clinically controlling BP to regulate constriction/relaxation function of blood vessels. Vascular elasticity, caliber, and reactivity are all characteristic indicators reflecting vascular function. Blood vessels are composed of three distinct layers, ...
There are three main types of blood vessels: Arteries.These begin with the aorta, the large artery leaving the heart. Arteries carry oxygen-rich blood away from the heart to all of the body's tissues. They branch several times, becoming smaller and smaller as they carry blood farther from ...
