Ch. 19-Circulatory System, Branches of the Aorta
| Question | Answer |
|---|---|
| study of the blood | hematology |
| study of the heart | cardiology |
| study of blood vessels | angiology |
| study of veins | phlebology |
| innermost layer of the blood vessels | tunica intima |
| primary tissue type of the tunica intima | endothelium |
| surface characteristic of the tunica intima | smooth surface |
| opening in the blood vessel, which allows blood to run through | lumen |
| middle layer of the blood vessels | tunica media |
| primary tissue type of the tunica media | smooth muscle tissue |
| characteristic of the tunica media | contrict/dilate |
| outermost layer of the blood vessel | tunica externa (adventitia) |
| primary tissue type of the tunica externa | connective tissue |
| characteristic of the tunica externa | support and anchor to other structures |
| order of blood vessels from the heart, then returning to the heart | arteries, arterioles, capillaries, venules, veins |
| of these, which bears the most pressure: veins, arteries, lymphatic vessels | arteries |
| these serve as backup routes for blood to flow if one link is blocked or otherwise compromised | anastomoses |
| T/F: Veins anastomose more frequently than arteries. | true |
| a term used in conjunction with anastomoses | collateral circulation |
| vessels of the vessels | vasa vasorum |
| primary vessel which exits the right ventricle | pulmonary trunk |
| these structures branch from the pulmonary trunk | 1 right pulmonary artery, 1 left pulmonary artery |
| these structures branch from the pulmonary arteries | 3 right lobar arteries, 2 left lobar arteries |
| these structures return oxygen-rich blood to the heart and empty into the left atrium | 2 right pulmonary veins, 2 left pulmonary veins |
| the vessel leaving the left ventricle | aorta |
| ascends from the left ventricle, feeds the heart walls and stops there | ascending aorta |
| lies posterior to the manubrium with three branches | aortic arch |
| the three branches of the aortic arch, in order: | braciocephalic trunk, left common carotid, left subclavian |
| the artery of the mediastinum that supplies blood to the right arm and the head and neck | braciocephalic artery |
| the braciocephalic artery divides into: | the right common carotid and the right subclavian |
| artery which divides in the neck to become the external and internal carotid arteries | left common cartoid |
| branch of the aortic arch which supplies blood to the head and arms, located in the upper thorax | left subclavian |
| what are the terminal branches of the aorta? | common iliacs |
| branches of the descending aorta which supply the cavity walls | parietal branches |
| branches of the descending aorta which supply the organs | visceral branches |
| posterior intercostal arteries | parietal branch of the thoracic aorta |
| subcostal arteries | parietal branch of the thoracic aorta |
| superior phrenic arteries | parietal branch of the thoracic aorta |
| esophageal arteries | visceral branch of the thoracic aorta |
| bronchial arteries | visceral branch of the thoracic aorta |
| pericardial arteries | visceral branch of the thoracic aorta |
| inferior phrenic arteries | parietal branch of the abdominal aorta |
| celiac trunk | *unpaired visceral branch of the abdominal aorta |
| superior mesenteric artery | *unpaired visceral branch of the abdominal aorta |
| suprarenal arteries | visceral branch of the abdominal aorta |
| renal arteries | visceral branch of the abdominal aorta |
| gonadal arteries | visceral branch of the abdominal aorta |
| inferior mesenteric artery | *unpaired visceral branch of the abdominal aorta |
| lumbar arteries | parietal branch of the abdominal aorta |
| median sacral artery | parietal branch of the abdominal aorta |
| three branches of the celiac trunk | left gastric artery, splenic artery, common hepatic artery |
