A&PII Lab 7: The Cardiovascular System: Blood Flow Dynamics

Question 1

Blood pressure

Answer 1

force established by ventricular systole (contraction); pressure exerted by the collision of blood against blood vessel walls

Question 2

Blood pressure gradient

Answer 2

the enormous difference in blood pressure between the aorta and the right atrium; causes blood to flow throughout the systemic circulation

Question 3

Systolic blood pressure

Answer 3

during ventricular systole, the pressure reaches its highest point

Question 4

Diastolic blood pressure

Answer 4

during ventricular diastole, blood pressure reaches its lowest point

Question 5

Arterial blood pressure

Answer 5

blood pressure in large muscular arteries

Question 6

Sphygmomanometer

Answer 6

blood pressure cuff

Question 7

Korotkoff sounds

Answer 7

the return of blood flow produces these tapping sounds, which can be heard with a stethoscope

Question 8

Pulse pressure

Answer 8

difference between systolic and diastolic blood pressure; represents the volume of blood ejected from the left ventricle, sometimes called the “working blood pressure”

Question 9

Mean arterial pressure (MAP)

Answer 9

average blood pressure during a single cardiac cycle
