final review 4

pressure difference between L and R of heart that product gradient allowing systemic movement of blood

CO = SV (stroke volume) x HR (heart rate)

preload

• afterload 
• determined by radius of arteries and degree of vessel compliance

peak pressure during cardiac systole

lowest pressure during cardiac diastole

primary factor influencing systolic pressure

major determinant of diastolic pressure

MAP = [(2 x diastolic pressure) + systolic pressure]/3

an increase

ANP cause the kidneys to increase sodium and water excretion by increasing the glomerular filtration rate

• normal : (S/D) <120/80
• prehypertension: 120-139/80-89
• Stage 1 hypertension: 140-159/90-99
• Stage 2: >160/100
