Q

What are the blood vessels?

A 
Artery
No valves
Oxygenated blood
High pressure
Carries blood away from heart
Thick walls
Vein
Valves prevent backflow
Deoxygenated blood
Low pressure
Carries blood to heart
Thin walls
Capillaries
No valves
Oxygenated and deoxygenated blood 
Enters under high pressure
Oxygenated to heart
Deoxygenated to veins
Thin walls
17
Q

What is vasoconstriction and vasodilation?

A

Vasoconstriction
Makes diameter smaller and reduces blood flow

Vasodilation
Increases diameter to allow more blood flow

18
Q

What is the tidal volume?

A

Amount of air breathed in and out in a normal breath

19
Q

What is residual volume?

A

Volume of air always left in lungs so they don’t collapse

20
Q

What is inspiration reserve volume ?

A

Amount of air you can forcefully inspire after normal inspiration

21
Q

What is expiratory reserve volume?

A

Amount of air you can forcefully inspire after normal expiration

22
Q

What happens to tidal volume, inspiratory and expiratory volume and residual volume during exercise?

A

Tidal volume steeper and more frequent

Inspiratory and expiratory volume decreases

Residual volume stays the same
