Cells need energy to function. They get this from cellular respiration.
Respiration needs glucose and oxygen
The formula: oxygen + glucose -> carbon dioxide + water + energy

Question 3

Small branches coming off the bronchus holding alveoli

Question 13

Air sacs containing oxygen where the gas exchange occurs

Question 14

What’s the diaphragm?

Answer 14

Bottom of the lungs. When inhaling it pulls air into the lungs. When exhales it relaxes and air is pushed out of the lungs
