| Question | Answer |
|---|---|
| tunics 3 layers | |
| need to know location of the arteries ... renal-kidney, etc | |
| diagram pg 262 "the loop" | |
| artery locations pg 263 | |
| circle of willis pg 267 | circle of willis -redundancy-back up system, connection between carotid arteries in case of blockage the brain still gets blood anastomoses-connection |
| the hepatic portal system pg 269 | http://www.google.com/imgres?imgurl=http://faculty.irsc.edu/FACULTY/TFischer/bio%25202%2520files/hepatic%2520portal%2520system.jpg&imgrefurl=http://faculty.irsc.edu/FACULTY/TFischer/bio%25202%2520files/Bio%25202%2520resources.htm&usg=__w_FUBveafo_7UHVOo7 |
| rteries moving blood away from the heart, elastic-thick wall- strong, large diameter-the amount of elastic tissue reduces the further away from the heart you go due to less pressure/volume | |
| arteriole branch off artery, capillary branch off arteriole | |
| capillaries only have the "inner tunica" one cell thick .... *many things can pass thru capillary walls by diffusion.... diffusion -no active transport so does not require energy from the body | |
| veins -muscle (middle layer) smaller and thinner, easily broken, most equipped with one-way valve so blood flows back to the heart only, veins have larger diameter 9:47pmMe | |
| gravity has to be overcome to get blood back from the legs, | |
| vericose veins -valves start to fail, knotty | |
| spider veins-dilated blood vessels near skin | |
| walking contracts muscles and keeps blood flowing also helps lymphatic system and veinous blood flow | |
| aortic aneurism pg 368 | mostly men effected over 60yrs, est 5% men over 60 have it,walls of aorta lose elasticity and can bulge widely with blood, as it grows, walls stretch more and weaken, increasing the risk of rupture if rupture occurs, can bleed to death in very short time |
| artherosclerosis pg 370 | cholesterol/plaque build up, usually 45yrs+, often have kidney problems -massage ok, but pay attention to any meds and side effects they may have |
| hyptertension pg 378 | high blood pressure, affect 1 in 3 adults, if taking meds be careful |
| renaud syndrome pg 382 | vein constriction in extremities *fingers/toes/nose* effect mostly women 15-40yrs, primary massage beneficial secondary ?? |
| varicose veins pg 385 | more women effected, approx 1/2 people over 50 effected, often caused by long period of standing -massage locally contraindicated |
