PPT-Arteries, Veins, and Special Circulation

Anatomy Ch 11 Part 3 Major Arteries Aorta largest artery in the body arises from the left ventricle of the heart Parts of the aorta Ascending aorta leaves the heart Aortic arch arches toward the left side of the body. and Veins . Learning Outcomes. Arteries have an outer layer of connective tissue containing elastic fibres and a middle layer containing smooth muscle with more elastic fibres. The elastic walls of the arteries stretch and recoil to accommodate the surge of blood after each contraction of the heart. The smooth muscle can contract or relax causing vasoconstriction or vasodilation to control blood flow. 18 Anatomy . of blood vessels. Joe Pistack MS/ED. Circulatory system. Circulatory System consists of the heart and blood vessels.. The blood vessels are a series of connected, hollow tubes that begin and end in the heart.. and Lower Extremities.

AORTA:. ● the aorta is the largest artery (diameter). ● the aorta can be divided into the:. *. ASCENDING AORTA. (as it emerges from the heart). Major Arteries of the Systemic Circulation. Aorta. It is the largest artery of the body . Different parts of the aorta are named for their location or shape:. Ascending aorta -> Aortic Arch -> Descending Thoracic Aorta -> Abdominal Aorta. THE PULMONARY AND SYSTEMIC CIRCULATION. .. THE PULMONARY CIRCULATION. CARRIES BLOOD BETWEEN THE HEART AND THE LUNGS.  THIS CIRCULATION BEGINS AT THE RIGHT VENTRICLE AND ENDS AT THE LEFT ATRIUM. 3. Oxygen-Poor blood is pumped out of the Right Ventricle of the Heart into the Lungs through the Pulmonary Arteries.  These are the only Arteries in the Body to Carry Deoxygenated Blood. . What are the four main components of blood?. Describe the features of a red blood cell which aids it’s transportation of oxygen.
