Acute Responses (Chapter 6)

Question 1

Heart Rate

Answer 1

How many times the heart beats per minute

Question 2

Stroke Volume

Answer 2

the amount of blood ejected by the left ventricle per beat

Question 3

Cardiac Output

Answer 3

the amount of blood pumped out of the heart per minute

Question 4

Blood Pressure

Answer 4

force exerted against the artery walls by the blood

Question 5

Systolic Blood Pressure

Answer 5

pressure in the arteries following contraction of ventricle as blood is pumped out of the heart

Question 6

Diastolic Blood Pressure

Answer 6

pressure in the arteries when the heart relaxes and ventricles fill with blood

Question 7

Vasodilation

Answer 7

an increase in the diameter of the blood vessel

Question 8

Vasoconstriction

Answer 8

a decrease in diameter of the blood vessel

Question 9

Respiratory Rate

Answer 9

the number of breathes per minute

Question 10

Tidal Volume

the amount of air inspired or expired per breath

Question 11

Ventilation

Answer 11

the amount of air breathed in or out per minute

Question 12

Ventilation equation

Answer 12

V= TV x RR
