Respiratory System and Diffusion Quiz

Why was diffusion not sufficient for larger organisms?

• It was only effective in water.

• It caused dehydration.

• It was too slow for larger oxygen demands.

• It required too much energy.

What evolutionary development allowed early life forms to breathe air?

• Lungs

• Trachea

• Gills

• Skin pores

What role does the diaphragm play in breathing?

• It moistens incoming air.

• It filters dust and particles.

• It contracts to expand the chest cavity.

• It prevents food from entering the lungs.

What is the function of the alveoli in the respiratory system?

• To pump blood

• To exchange gases

• To filter air

• To produce mucus

How does the trachea remain open during breathing?

• It is supported by muscle tissue.

• It is reinforced with cartilage rings.

• It is filled with air.

• It is surrounded by bone.

What is the primary reason for warming and moistening incoming air?

• To reduce air pressure

• To prevent lung cells from drying out

• To enhance smell

• To increase oxygen concentration

What is the main advantage of having a respiratory system with both bulk flow and diffusion?

• It reduces energy consumption.

• It allows for rapid and efficient gas exchange.

• It increases body temperature.

• It prevents infections.
