Anatomy And Physiology Of Blood Vessels

Blood pumped by the heart flows through a series of vessels known as arteries arterioles capillaries venules and veins before returning to the heart. Capillaries are the smallest blood vessels walls consisting of a thin tunica interna one cell thick allow only a single rbc to pass at a time pericytes on the outer surface stabilize their walls there are three structural types of capillaries.

Blood Vessel Histology Human Anatomy And Physiology

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

Anatomy and physiology of blood vessels. Eventually the smallest arteries vessels called arterioles further branch into tiny capillaries where nutrients and wastes are exchanged. An artery is a blood vessel that carries blood away from the heart where it branches into ever smaller vessels. Skip navigation sign in.

Blood is carried through the body via blood vessels. Exchanges of nutrients respiratory gases and wastes can occur only through thin capillary walls. Arteries transport blood away from the heart and branch into smaller vessels forming arterioles.

Arterioles distribute blood to capillary beds. All other vessels serve simply to feed or drain capillary beds. Arteries transport blood away from the heart and branch into smaller vessels forming arterioles.
