Cardiovascular system • 400,000,000 alveoli • alveoli look like a bunch of grapes

• 100 m2 of surface http://library.med.utah.edu/kw/pharm/hyper_heart1.html

The heart - four chambers - 2 atria - 2 ventricles - 4 chambers - left ventricle and left atrium are on the right side - right side of the heart receives blue blood because it is.. - veins carry bring blood to the heart From a vein to the right atrium Pulse is blood pushing through your arteries Everytime the heart contracts you feel the pressure

"Lub"- valve between atrium and ventricle shuts "Dub"- valve between ventricle and artery shuts

blood pressure- normal: 120/80 Systole- big number - it is the pressure blood after the heart contracts Diastole- the blood pressure when the heart is relaxed
