Q

Cardiac output

A

Stroke volume x heart rate
= amount of blood pumped out per min
At rest 80mL x 60 bpm = 4800 mL/m
Max exercise 130mL x 200 bpm = 26000 mL/m

15
Q

Syphgmomanometer

A

Measures blood pressure
Typical reading
120 mmhg
80 mmhg

16
Q

Vascular network blood flows through

A
Arteries - arterioles 
Away from the heart
Cappilaries 
Muscles
Venules - veins
Back to the heart
17
Q

Precappilary sphincter

A

A band if smooth muscle that adjusts the blood flow into each capillary

18
Q

Pulmonary diffusion

A

The gaseous exchange that occurs in the lungs

19
Q

Respiratory system network

A
Nose/mouth
Pharaynx
Larynx
Trachea
Bronchus ( left or right)
Bronchi
Bronchioles
Alveoli
20
Q

Tidal volume

A

Amount of air inhaled and exhaled per breath average 500-600

21
Q

Pulmonary/minute ventilation (Ve)

A

= respiratory rate x tidal volume

At rest = 12 x .5 = 6.0L/min

22
Q

Vital capacity

A

The amount of oxygen your lungs can hold

23
Q

Steady state

A

Oxygen supply = oxygen demand
Experienced when jogging
When oxygen supply cannot equal the demand it is know as VO2 maximum

24
Inspiration
Breathing in Chest expands Diaphragm contracts Volume of lungs increase
25
Expiration
Breathing out Chest contracts Diaphragm relaxes Volume of lungs decrease
26
Functions of pulmonary diffusion
Provide body with oxygen Remove carbon dioxide Happens between alveoli and cappilaries
27
Arteriovenous oxygen difference | A- VO2 diff
Indication of oxygen concentration between the veins and arteries How much oxygen the body used At rest: 15ml O2 per 100ml As exercise intensity rises the avo2 diff will increase
