Definitions Exam 2 Flashcards
1
Q
Venous return
A
blood flow back to right atrium
2
Q
Cardiac output
A
stroke volume x HR
3
Q
stroke volume
A
EDV - ESV (100-40mL = 60mL)
4
Q
Peripheral resistance
A
resistance of the arteries to blood flow
5
Q
- Tidal Volume
A
o normally breathing: starts at 2500 to 3kmL (500mL coming in and 500 mL going out)
6
Q
IRV
A
forceful intake of air beyond tidal volume (2800-3100mL)
7
Q
- ERV
A
forceful exhale of air beyond tidal volume (13-1200mL)
8
Q
- RV
A
air that remains in lungs to keep alveoli open (1200mL)
9
Q
- IC (
A
– total amount of air during intake (TV + IRV)
10
Q
- EC
A
– total amount of air during expiration (TV + ERV)
11
Q
- FRC (Functional Residual Capacity
A
ERV + RV)
12
Q
- VC
A
- total volume of air that can be brought in and exhaled forcefully (IRV + TV + ERV)
13
Q
- TLC
A
(TV + ERV+IRV+RV) = 5800mL
