Front

What are the air sacs in the lungs where gas exchange occurs?

Back

Alveoli

Front

What is the primary function of alveoli?

Back

To facilitate gas exchange between air and blood.

Front

What adaptations do alveoli have for efficient gas exchange?

Back

Thin walls and a large surface area.

Front

What surrounds the alveoli to aid in gas exchange?

Back

Capillaries.

Front

What gas do we inhale during breathing?

Back

Oxygen.

Front

What gas do we exhale during breathing?

Front

What is the process of taking in air and expelling it called?

Back

Breathing.

Front

What is the difference between respiration and breathing?

Back

Breathing is the mechanical process of inhaling and exhaling air, while respiration is the biochemical process of converting oxygen into energy.

Front

What role do capillaries play in gas exchange?

Back

They transport oxygen and carbon dioxide to and from the alveoli.

Front

Why is it important for alveoli to have a large surface area?

Back

To maximize the amount of gas that can be exchanged.
