blood pressure

Question 1

define blood pressure

Answer 1

the lateral pressure exerted by the movinf column of blood on the walls of the vessels

Question 2

define systolic BP and normal value

Answer 2

• the max arterial pressure during the systole
• n: 120 (100-130 mmHg)

Question 3

define diastolic BP

Answer 3

the min arterial pressure during diastole
-n: 80 mm Hg ( 60-90)

Question 4

define pulse pressure and norm val

Answer 4

-the arithmetic difference between the systolic and diastolic blood pressures
n:40 mmHg

Question 5

define mean arterial BP and norm

Answer 5

the average of all pressure measured ms by ms throughout the cardiac cycle
MAP= DP + 1/3 PP
n:90-100 mmHg

Question 6

importance of mean arterial pressure

Answer 6

-regional blood flow through an organ
- cardiovascular reflexes are sensitive to MAP
