The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries. Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart.

Veins. Blood vessels that carry blood back to the heart. Veins. Have valves to prevent backflow. Aorta.

Differences between Arteries and Veins. Arteries and veins are two of the body's main type of blood vessels through which blood flow in the body. The arteries carry oxygenated blood away from the heart while the veins carry deoxygenated blood from the tissue capillaries back towards the heart.

Veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs.

Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. ... They're part of two closed systems of tubes that begin and end at the heart.

Mature xylem tissues are composed of three main cell types: xylem tracheary (vessel) elements, xylary fibres, and xylem parenchyma cells (Fig. 1).

In your blood, there are three types of cells. They're commonly known as red blood cells, white blood cells and platelets - and formally named erythrocytes, leukocytes and thrombocytes. These cells move throughout your body in your blood to carry oxygen, fight infections and stop bleeding if a blood vessel is damaged.

Arteries are blood vessels that carry blood away from the heart. This blood is normally oxygenated, with the exception of blood in the pulmonary artery. Arteries typically have a thicker tunica media than veins, containing more smooth muscle cells and elastic tissue.

Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.

As in the arteries, 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.

Capillary. Blood vessels that are only one-cell layer think and allow for the rapid exchange of oxygen and nutrients for carbon dioxide and waste products. Venule. Tiny veins that connect veins and capillaries and help to drain blood back to the heart.

Arteries are blood vessels that carry blood back to the heart. The arteries and veins are connected through a series of blood vessels called the capillaries. These red-colored blood filled capillaries are close to the thin skin on your lips, so your lips appear red.

Blood cells are produced by bone marrow. The three major types of cells in the blood are red blood cells, white blood cells, and platelets. Red blood cells determine blood type and are responsible for transporting oxygen.
