blood vessels
| Question | Answer |
|---|---|
| blood vessels | arteries, arterioles, capillaries, veinules, veins |
| arteries, arterioles, capillaries, veinules, veins, heart | are a closed system |
| capillaries | exchange happens in capillaries |
| arteries + arterioles | 4 functions, 1)carry blood away from heart. 2)carry oxygenated blood except pulmonary arteries. 3)contain blood under highest pressure. 4)have thick muscular elastic walls. |
| lumen | hollow part of artery |
| arteriosclerosis | hardening of artery, if the walls of the artery harden |
| atherosclerosis | lumen fills up with fatty material (plague) - repaired by bypass surgery |
| veins + veinules | 5 functions. 1)carry blood toward the heart. 2)carry unoxygenated blood except pulmonary vein. 3)contain blood under low pressure. 4)have thin walls,little muscle. 5)veins have oneway valve that prevents back flow of blood |
| capillaries | 1)smallest vessels, 2)place where gas exchange takes place. 3)thinnest walls 1cell thick.4)form extensive networks(capillary beds |
| exchange | law of diffusion makes the change happen. body of cells o2 out of cap.+ co2 into. lungs o2 into cap co2 out of cap. |
| common coratid | carry blood to head |
| brachial artery | bring blood to arm |
| aortic arch | aortic foms loops run down next to spine |
| phrenic artery | diaphram |
| hepatic artery | liver |
| gastric artery | stomach |
| mesentreric artery | stomach |
| splenic artery | spleen |
| pancreatic artery | pancreas |
| removal artery | kidneys |
| lumbar | spine, muscles of lower back |
| pulmanary artery | lungs |
| iliac artery | legs |
| femoral artery | thigh |
| coronary arteries | nourishes the heart muscles |
| dorsal or descending aorta | main then branch off |
| vein's | all the same eccept the ones in the neck |
| neck | jugular vein, drains, head region, superior vena cavae, inferior vena cavae |
| phrenic vein | diaphram |
| gastric vein | stomach |
| messentenic vein | messentary |
| coronary veins | nourishes heart |
| pulse | heart rate, felt in artery |
| heart rate | systole+ diastole. 120/80 is average= mm of mercury |
| systole | heart contraction top # systolic pressure |
| diastole | heart contraction bottom # diastolic pressure |
| high blood pressure | hyper tension |
| low blood pressure | hypotension |
| fast heart rate | brady cardia |
| MI | myo/cardio/infarction= death of heart muscles |
| coronary thrombosis | blockage(clot) in coronary artery |
| black out | blood collects in lower part of the body= faint |
| red out | blood gets forced into head region =faint |
| muscle bound heart | idiopathic/hypertrophic/cardio/myopathy |
| sinus arrythmia | irregular heart beat |
| heart murmur | leaky heart valve |
| foramen ovale | hole in heart septum |
| wenckebach phenomenon | heart skips a beat |
| circus movement | enlarged heart, several small beats |
| stroke (cva) | broke or block vessels in brain |
| aneurysm | weak spot in wall of an artery |
| phlebitis | inflammation of vein |
| TIA | transischemic attacks "little strokes" |
| tetrology of fallot | heart displaced toward the right side of your chest |
| congestive heart failure (CHF) | pulmanary edema, failure of the left side of heart, blood backs up into lung, fluid leaves the blood, enters the lung =drown |
| angina | chest pain- partial blockage constriction of coronary arteries |
