Anatomy Blood Vessels

Aside from capillaries blood vessels are all made of three layers. Arteries arterioles capillaries venules and veins.

All arteries have relatively thick walls that can withstand the high pressure of blood ejected from the heart.

Anatomy blood vessels. There are five main types of blood vessels. An artery is a blood vessel that carries blood away from the heart where it branches into ever smaller vessels. Blood vessels are found throughout the body.

All other vessels serve simply to feed or drain capillary beds. The function and structure of each segment of the peripheral vascular system vary depending on the organ it supplies. Blood is carried through the body via blood vessels.

Blood vessels also play a role in controlling your blood pressure. Arteries carry blood away from the heart to other organs. Exchanges of nutrients respiratory gases and wastes can occur only through thin capillary walls.

Arteries that distribute blood to a particular muscle or organ. An artery is a blood vessel that conducts blood away from the heart. The high blood pressure in arteries propels the blood through them.

All arteries have relatively thick walls that can withstand the high pressure of blood ejected from the heart. The adventitia or outer layer which provides structural support and shape to the vessel. The vessels that carry blood away from the heart are called arteries and their very small branches are arterioles.

A blood vessels main function is to transport blood around the body. Tunica media dominated by smooth muscle arterioles smaller arteries with high resistance and small diameter. The venules and veins are returning blood to the heart.

Blood vessel a vessel in the human or animal body in which blood circulates. Eventually the smallest arteries vessels called arterioles further branch into tiny capillaries where nutrients and wastes are exchanged. Very small branches that collect the blood from the various organs and parts are called venules and they unite to form veins.

The blood pressure in veins is low and often the blood is flowing against gravity.
