A&P arteries
systemic circulation
| Question | Answer |
|---|---|
| aorta supplies blood to what parts of the body? | all parts |
| the first branch of aortic arch | brachiocephalic trunk |
| what arises from brachiocephalic trunk? | R common carotid & R subclavian arteries |
| two arteries arising separately from aortic arch | L common carotid & L subclavian arteries |
| R common carotid arises from | brachiocephalic artery |
| L common carotid arises from | directly from aortic arch |
| 3 prominent branches of external carotid artery | facial, superficial temporal, occipital |
| internal carotid supplies blood to the | brain |
| R subclavian artery arises from | brachiocepahlic artery |
| L subclavian arises from | directly from aortic arch |
| R & L subclavian arteries supply blood to | arms, shoulders, chest wall , back, brain, spinal cord |
| vertebral artery arises from | subclavian artery |
| both vertebral arteries supply blood to the | brain and spinal cord |
| as each subclavian passes the first rib and enters the shoulder and armpit it becomes the | axillary artery |
| the axillary artery supplies blood to the | shoulder and head of humerous |
| each axillary continues in the upper arm as the | brachial artery |
| the brachial artery supplies blood to the | rest of the upper arm |
| each brachial artery divides at the elbow to form the | radial and ulnar arteries |
| the radial and ulnar a's supply blood to the | forearm |
| the radial and ulnar a's reunite to form the | palmar arches in hand |
| celiac trunk arises from the | abdominal aorta just inf. to diaphragm |
| celiac trunk gives rise to which 3 branches? | common hepatic, left gastric, splenic |
| common hepatic supplies blood to the | liver, stomach, gall bladder, and sm. intestine |
| L gastric supplies blood to | stomach and lower esophagus |
| splenic artery supplies blood to | spleen, stomach and pacreas |
| superior mesentaric arises from | the abdominal aorta about 1 in. below celiac trunk |
| sup. mesentaric supplies blood to | sm. intestine, pancreas and most of lg. intestine |
| renal arteries emerge from | abdominal aorta just inferior to sup. mesentaric |
| renal a's supply blood to | kidneys |
| gonadal a's arise from | abdominal aorta just below renal a's |
| gonadal a's supply to | either ovaries or testes |
| inf. mesentaric arises from | abdominal aortaa below gonadal a's |
| inf. mesentaric supply to | last part of colon and rectum |
| near 4th lumbar vertebra, aorta divides to form the two | common iliac a's |
| common iliac a's supply t o | pelvis and lower extremities |
| why are common iliac a's called as such? | b/c each one divides forming and internal and external iliac artery |
| internal iliac is the inner branch of the | common iliac |
| internal iliac supplies to | pelvic organs and medial side of thigh |
| external iliac is the outer, larger branch of the | common iliac |
| external iliac supplies to | lower extremities |
| after penetrating lower abdominal wall, the external iliac becomes the | femoral artery |
| about 2 in. below abdominal wall, femoral gives rise to the | deep femoral |
| deep femoral supplies | to some of skin of thigh and deep thigh muscles |
| behind the knee, femoral becomes the | popliteal |
| the popliteal divides to become | the anterior and posterior tibial a's |
| post. tibial passes down | post. surface of tibia |
| as the ant. tibial passes across the top of the ankle it becomes | the dorsalis pedis |
| the dorsalis pedis artery supplies to the | ankle and part of the foot |
| the dorsalis pedis divided to form the | dorsal arch |
| sm. a's branch off the dorsal arch & supply to the | toes and parts of feet |
| post. tibial divides at ankle to form arterial loop called | plantar arch |
| plantar arch supplies | toes and part of foot |
| basilar artery is formed by the union of the two | vertebral a's |
| basilar a' supplies to | spinal cord, medulla oblongata, pons |
| post. cerebral a's supply to | the post. part of cerebrum |
| post. communicating a's connect the | post. cerebral a's to internal carotid a's |
| middle cerebral supply to | most of temporal, parietal and frontal lobes |
| pulmonary trunk carries ________ blood out of the __________ | deoxygenated, right ventricle |
| R & L pulmonary a's are colored blue on drawings- why? | b/c they carry deoxygentated blood |
| R& L pulmonary v's are colored red on drawings- why? | they return oxygenated blood from lungs |
