Circulatory Pathways - Systemic Circulation • Function: Brings oxygenated blood supply to all the body’s tissues, delivers nutrients from digestive tract to tissues and carried away CO2 and metabolic waste. • Oxygen Rich Blood Flow: Oxygen rich blood is pumped from the heart: > left ventricle through the semilunar valve* into the ascending aorta> *Opposite each semilunar valve cusp is an aortic sinus which contains pressoreceptors involved in blood pressure regulation. The semilunar valve prevents the back flow of blood back into the heart. > ascending aorta arches up (in front of pulmonary trunk) and gives off right and left coronary arteries> > ascending aorta becomes the aortic arch> > aortic arch gives off the brachiocephalic trunk (under right clavicle)> > the brachiocephalic trunk branches into right common carotid artery and right subclavian artery. > Next aortic arch gives off the left common carotid artery and the right subclavian artery> > aortic arch becomes the descending aorta> right vertebral artery right common carotid artery left common carotid artery right subclavian artery left subclavian artery ascending aorta aortic arch descending aorta thoracic artery Circulatory Pathways - Systemic Circulation right common carotid artery right vertebral artery left common carotid artery right subclavian artery braciocephalic trunk ascending aorta left subclavian artery aortic arch left ventricle right lung (3 lobes) descending aorta left lung (2 lobes) thoracic aorta Arteries of the Circulatory System vertebral artery common carotid artery subclavian artery (shoulder) axillary artery (armpit) coronary arteries inferior phrenic celiac trunk (3 branches): • common hepatic artery • splenic artery • left gastric artery suprarenals superior mesenteric renals gonadals inferior mesenteric lumbar arteries common iliac artery internal iliac artery brachial artery (upper arm) radial artery (lateral forearm) ulnar artery (medial arm) digital arteries external iliac artery median sacral artery deep femoral artery femoral artery popliteal artery (behind knee) anterior tibial artery posterior tibial artery arcuate artery dorsal metatarsal arteries
