Anatomy Of Veins And Arteries

The walls of veins and arteries are both made up of three layers. Because the arteries arterioles and capillaries absorb most of the force of the hearts contractions veins and venules are subjected to very low blood pressures.

Anatomy of veins and arteries. This vein accompanies the maxillary artery and drains blood from the face. It begins at the angular vein in the medial angle of the eye. These are reddish in color.

Arteries carry oxygenated blood away from the heart to the body and veins carry oxygen poor blood back from the body to the heart. Structure and function of blood vessels the chief difference between arteries and veins is the job that they do. The deep facial vein joins the facial vein which goes on to drain into the internal jugular vein.

The inner layer of the blood vessel wall is called. The head and neck receives the majority of its blood supply through the carotid and vertebral arteries. Anatomy of arteries vs veins.

To ensure unrestricted flow of blood a venule blood vessel allows deoxygenated blood to return from the capillary beds to the vein. The vein also contains venous valves one way flaps that prevent blood from flowing back and pooling in the lower extremities due to the effects of gravity. Difference between arteries and veins.

Arteries carry oxygenated blood to the organs and limbs while veins carry the deoxygenated blood back to the heart for re oxygenation. Difference between arteries and veins. While both arteries and veins are blood vessels they are quite different.

The largest artery is the aorta the main high pressure pipeline connected to the hearts left ventricle. Veins are the large return vessels of the body and act as the blood return counterparts of arteries. Each artery is a muscular tube lined by smooth tissue and has three layers.

Tunica adventitia tunica externa is the outer layer of a blood vessel. The facial vein drains most of the blood from the face. The middle layer of the walls of arteries and veins is called the tunica media.

Arteries carry oxygenated blood away from the heart except pulmonary artery. These are thick walled highly muscular except arteries of cranium and vertebral column. These are mostly deeply situated in the body.

The arteries are the blood vessels that deliver oxygen rich blood from the heart to the tissues of the body. The only exception are the pulmonary veins which carry oxygenated blood from the lungs to the heart. This article shall explore the anatomy of this arterial system its anatomical course branches and clinical correlations.

The function of arteries and veins. These posses narrow lumen.
