Anatomy Blood Vessels

The blood pressure in veins is low and often the blood is flowing against gravity. Eventually the smallest arteries vessels called arterioles further branch into tiny capillaries where nutrients and wastes are exchanged.

How The Heart Blood Vessels Work Heart Vascular

Arteries that distribute blood to a particular muscle or organ.

Anatomy blood vessels. The adventitia or outer layer which provides structural support and shape to the vessel. All arteries have relatively thick walls that can withstand the high pressure of blood ejected from the heart. Exchanges of nutrients respiratory gases and wastes can occur only through thin capillary walls.

Blood is carried through the body via blood vessels. Tunica media dominated by smooth muscle arterioles smaller arteries with high resistance and small diameter. The high blood pressure in arteries propels the blood through them.

The vessels that carry blood away from the heart are called arteries and their very small branches are arterioles. Aside from capillaries blood vessels are all made of three layers. The venules and veins are returning blood to the heart.

Arteries carry blood away from the heart to other organs. Blood vessels are found throughout the body. An artery is a blood vessel that carries blood away from the heart where it branches into ever smaller vessels.

Very small branches that collect the blood from the various organs and parts are called venules and they unite to form veins. A blood vessels main function is to transport blood around the body. All arteries have relatively thick walls that can withstand the high pressure of blood ejected from the heart.

The function and structure of each segment of the peripheral vascular system vary depending on the organ it supplies. Arteries arterioles capillaries venules and veins. An artery is a blood vessel that conducts blood away from the heart.

All other vessels serve simply to feed or drain capillary beds. Blood vessels also play a role in controlling your blood pressure. There are five main types of blood vessels.

Blood vessel a vessel in the human or animal body in which blood circulates.
