Anatomy and physiology blood vessels. Physiology and Anatomy of. Blood Vessels Prepared by Dr. Naim Kittana PhD.

Physiology of Circulation Dr. Naim Kittana PhD 32. Blood Flow Blood flow is the volume of blood flowing through a vessel an organ or the entire circulation in a given period mlmin.

Blood vessels comprise the vascular system. All blood vessels consist of a similar basic structure which includes. Tunica Intima This is the inner thinnest layer.

Tunica Media This is the middle thickest layer. Tunica Adventitia This is an outermost layer and contains nerves. 201 Structure and Function of Blood Vessels Learning Objectives.

By the end of this section you will be able to. Compare and contrast the three tunics that make up the walls of most blood vessels. Distinguish between elastic arteries muscular arteries and arterioles on the basis of structure location and.

Structure and Function. Vessels transport nutrients to organstissues and to transport wastes away from organstissues in the blood. A primary purpose and significant role of the vasculature is its participation in oxygenating the body.

Deoxygenated blood from the peripheral veins is transported back to the heart from capillaries to venules to veins to the right side of the heart and then. Anatomy and Physiology I. ANATOMY OF BLOOD VESSELS A.

Three Layers Tunicae of Blood Vessels Fig. Tunica interna or intima. This is the innermost layer and is composed of endothelial cells.

This is the middle layer and is composed of smooth muscle and elastic fibers. Arteries transport blood away from the heart and branch into smaller vessels forming arterioles. Arterioles distribute blood to capillary beds the sites of exchange with the body tissues.

Capillaries lead back to small vessels known as venules that flow into the larger veins and eventually back to the heart. Components of circulatory system that transport blood throughout the body. Transport blood cells nutrients and oxygen to the tissues of the body.

Also remove carbon dioxide and metabolic wastes from the tissues. Arteries capillaries and veins. Carry blood away from the heart.

Oxygenated except for pulmonary circulation and umbilical vessels of a fetus. Contact tissue cells and directly serve cellular needs. Size allows only a single RBC to pass at a time.

Move blood away from heart. Smallest branches of arteries little or no tunica externa thin or incomplete tunica media. Smallest blood vessels exchange between blood and interstitial fluid.

Blood vessels consist of arteries arterioles capillaries venules and veins. Vessel networks deliver blood to all tissues in a directed and regulated manner. Arteries and veins are composed of three tissue layers.

The thick outermost layer of a vessel tunica adventitia or tunica externa is made of connective tissue. Larger arteries and veins contain small blood vessels within their walls known as the vasa vasorumliterally vessels of the vesselto provide them with this critical exchange. Since the pressure within arteries is relatively high the vasa vasorum must function in the outer layers of the vessel see Figure 622 or the pressure.

Blood pressure. Contraction of the ventricles generates blood pressure the hydrostatic pressure exerted by blood on the walls of a blood vessel. BP is highest in the aorta and large systemic arteries in a resting young adult BP rises to about 110mmHg during systole and.

Study Flashcards On Anatomy Physiology-Marieb-Ch 19. Quickly memorize the terms phrases and much more. Different types of blood vessels vary slightly in their structures but they share the same general features.

Arteries and arterioles have thicker walls than veins and venules because they are closer to the heart and receive blood that is surging at a far greater pressure Each type of vessel has a lumen a hollow passageway through which blood flows. Anatomy and Physiology Video of Blood Vesselsanatomy and physiology for dummies 3d anatomy heart arteries human anatomy physiology anatomy games anatomy bo. Blood vessel a vessel in the human or animal body in which blood circulates.

The vessels that carry blood away from the heart are called arteries. Veins are vessels that return blood to the heart. Learn more about the anatomy and types of blood vessels and the diseases that affect them.
