BSC-II Exercise Physiology

what is the effect of capillarisation on diffusion rate in the working muscles

• more capillaries decreases the exchange of gases in the muscle

• less capillaries will help diffusion

• more capillaries will increase gas exchange and diffusion in the muscle

• more capillaries will have no effect in the diffusion rate

which response occurs first in the body when we exercise

• heart rate lowers

• anticipatory rise from adrenaline

• blood pressure increases

• adrenaline lowers

what is stroke volume

• volume of blood per minute

• volume of air per minute

• volume of blood per beat

• volume of blood and air per minute

what is cardiac output

• volume of blood per minute

• volume of air per minute

• volume of blood per beat

• volume of blood and air per minute

A signal being sent down the parasympathetic nervous system to the heart will...

• speed up the heart

• speed up breathing rate

• slow down the heart rate

• reduce blood resistance
