Question 1

How does glucose get into cells?

Answer 1

Digestion breaks down food which is dissolved into our blood stream. The liquid part of the blood called plasma dissolves the glucose int smaller particles which then goes into cells for respiration.

Question 2

How does oxygen get into cells?

Answer 2

When you breath in oxygen it goes to the alveoli. The oxygen then diffuses through and goes into a red blood cells haemoglobin which carries it around the body. When there is a cell that needs oxygen the red blood cell will release the oxygen and it will go to that cell.

Question 3

How does carbon dioxide get out?

Answer 3

When respiration happens in a cell the carbon dioxide will diffuse into the blood plasma which carry’s it to air sacks in the lungs so when you exhale the carbon dioxide will leave your body.
