Q

In animals how do we get glucose how does oxygen travel how does carbon dioxide get removed and what happens to water

A

Glucose comes from the food we eat
Oxygen comes from the air in our lungs and is carried in the blood by the circulatory system
Co2 is removed by blood through the circulatory system and exhaled by the lungs
Water is moved by kidneys which are part of our excretory system and also exhaled by our lungs

Q

Why do fitter people breakdown lactic acid quicker

A

The body can go back into aerobic respiration they pump more oxygen because of the heart so less lactic acid

Q

What are ways our body responds to exercise to maximise the respiration in the body

A

Increasing breathing
Heart rate
Blood vessels dilute that supply oxygen to the cells for respiration

17
Q

Which organelle is responsible for the breakdown of lactic acid

A

Liver

18
Q

Why does lactic acid need to be broken down

A

It will cause muscle fatigue

19
Q

Define the term oxygen debt

A

The oxygen needed to break down lactic acid

20
Q

Why is glycogen used up when you exercise

A

Because glucose is used to release energy
