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.. Day 1. WHAT ARE WE LEARNING TODAY?. BENCHMARK.

Blood leaves heart through pulmonary trunk and aorta. Vessels branch forming major arteries that carry blood to body organs. SLO 2. Blood Vessels can be divided into five groups:. Arteries . Carry blood away from the heart towards tissues. The heart’s ventricles pump blood into the arteries. Blood Vessels. Arterioles. Small subdivisions of the arteries.
