APHY 102: the Cardiovascular System Latest Update Graded A+

APHY 102: the Cardiovascular System Latest Update Graded A+ Aneurysm a bulge in the wall of an artery, formed when blood pressure dilates a weakened area of the vessel that can burst wall of artery Anterior Interventricular Artery Branch of left coronary artery along anterior interventricular sulcus; upplies blood to both ventricles Aorta supplies oxygenated blood to systemic circuit Aortic semilunar valve valve which regulates blood flow from the left ventricle to the aorta, prevents backflow of blood into the left ventricle Aortic valve the semilunar valve separating the aorta from the left ventricle that prevents blood from flowing back into the left ventricle Apex of the heart Where ventricular contractions begin Arteries strong, elastic vessels adapted for transporting blood away from the heart under relatively high pressure Atrioventricular (AV) node conducts impulses from SA node to AV bundle Auricles small, earlike projections that extend anteriorly from the atria, slightly increasing atrial volume Blood flow through the pulmonary circuit Blood flow through the pulmonary circuit before being ejected by the right ventricle 1. Pulmonary Trunk 2. Pulmonary Arteries 3. Lobar Arteries 4. Alveolar Capillaries 5. Pulmonary Veins 6. Left Atrium Blood flow to the deep and superficial palmar arches
