!1: arterioles=little arteries, small branches of the arteries that connect the larger arteries to capillaries. Functions: normal pulse fluctuations, either up or down from 72, are in response of either the nervous or hormonal systems. Lub, the first sound, occurs when increased pressure forces the flaps of he av-valves to close. !3: systolic pressure is the maximum pressure in arteries during systole; diastolic pressure is the minimum pressure in arteries during diastole. It appears in the blood 3 4 hours after a heart attack, peaks at 12 -16 hours and stays at elevated for two weeks. !4: hypertension or high blood pressure this is referred to as the silent killer because many people do not exhibit symptoms, this occurs in nearly all victims of cardiovascular disease, control of hypertension includes: 1) weight loss and salt restriction: drugs called beta-blockers, reduced stress.
