Which of the following is NOT a method of gas exchange used in the animal kingdom?

through the pads under their paws

Gas exchange also happens at the capillaries throughout the body. What is involved here?

CO2 entering the blood and oxygen leaving it

What happens when we breathe IN?

the diaphragm moves down and the rib cage moves out/up

What does gas exchange within the lungs involve?

oxygen entering the blood and CO2 leaving the blood

Having a big surface area in the lungs is important because

it allows for very efficient and quick gas exchange
