The high blood pressure in arteries propels the blood through them. Blood is carried through the body via blood vessels.
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. Anatomy and physiology of blood vessels anatomy and physiology for dummies 3d anatomy heart arteries human anatomy physiology anatomy games anatomy book an. Blood pumped by the heart flows through a series of vessels known as arteries arterioles capillaries venules and veins before returning to the heart. Arterioles distribute blood to capillary beds.
An artery is a blood vessel that carries blood away from the heart where it branches into ever smaller vessels. Arterioles distribute blood to capillary beds. Arteries transport blood away from the heart and branch into smaller vessels forming arterioles.
Eventually the smallest arteries vessels called arterioles further branch into tiny capillaries where nutrients and wastes are exchanged. Continuous fenestrated and sinusoids. 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.
All other vessels serve simply to feed or drain capillary beds. Blood pumped by the heart flows through a series of vessels known as arteries arterioles capillaries venules and veins before returning to the heart. Skip navigation sign in.
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.
