Document Summary

Cells need oxygen and nutrients and have waste products taken away. Arteries (from the heart) and veins (to heart: blood pressure (bp) Blood pressure represented by both e. g. 120 over 80. (cid:272)o(cid:374)siste(cid:374)tl(cid:455) high bp (cid:863)h(cid:455)pe(cid:396)te(cid:374)sio(cid:374)(cid:863) ; s(cid:455)stoli(cid:272) a(cid:271)out (cid:1005)(cid:1008)(cid:1004); diastoli(cid:272) over 90. If beating more than blood pressure tends to go up. Big vessels going into smaller vessels pressure increases. Difficulty fluid has in passing through narrow openings (e. g. arterioles) Meal intestine arterioles expand, more blood there, pressure lower digestion increase. Pushing the elastic stuff in the balloon more. Some people have higher number of red blood cells. More think, more pressure needed to move it: temperature. If hot then peripheral vessels expand and blood pressure go down. 3) emotional experience (e. g. stress, anger increase blood pressure) Atherosclerosis: build-up of fatty (e. g. cholesterol) patches (plaques) in vessels. Inflammation (redness, swollen, etc. ) response some people more susceptible. Fatty chunk may break free and contribute to narrowing.
