AQA GCSE PE Applied anatomy and physiology overview quiz quiz

Producing lactic acid during short bursts of high-intensity exercise

Gaseous exchange between the air and the blood in the air sacs of the lungs

Removing carbon dioxide from the blood and breathing it out of the body

Support, protection, movement, blood cell production and mineral storage

It contracts to produce the movement

It relaxes while its partner contracts

It supplies oxygen to the muscle

It connects muscle to bone

Hinge joint, like the elbow or knee

Ball and socket joint

Pivot joint, like the top of the neck

Gliding joint, like those in the wrist

The trachea

The bronchi

The alveoli

The diaphragm

It beats exactly twice as fast during exercise as it does at rest

It has only two valves, one on the left side and one on the right

It stores both oxygen and carbon dioxide ready for the muscles to use

It pumps blood to the lungs and to the rest of the body

Glucose plus oxygen produces energy plus carbon dioxide plus water

Glucose plus oxygen produces energy plus lactic acid and nothing else

Oxygen plus carbon dioxide produces glucose plus water in the muscle

Lactic acid plus oxygen produces glucose plus energy without water

Carbon dioxide

Lactic acid

Water

Glucose

The oxygen stored in the muscles before the exercise even begins

The oxygen that is lost from the body through sweating during exercise

The extra oxygen needed after exercise to break down lactic acid

The oxygen used by the brain while the body is resting completely

Cardiac hypertrophy, where the heart muscle grows larger

A lower resting heart rate that develops over many weeks

Stronger bones built up gradually through regular training

An increased heart rate during the activity

An increase in the size of muscles from regular training

A decrease in the size of muscles caused by a long period of inactivity

The build-up of lactic acid in the muscles during high-intensity exercise

The relaxing of the antagonist muscle while its partner contracts to move

It decreases, so less blood is pumped out with every single beat

It increases, so more blood is pumped per beat

It stays exactly the same, as training has no effect on it at all

It only changes during the activity and returns to normal afterwards

Aerobic, because the race is long and run at a low intensity

Neither aerobic nor anaerobic, as it uses no energy system

Anaerobic, because it is short and high intensity

Aerobic, because no lactic acid is produced during the race
