Explain the role of diaphragm in the mechanism of breathing.
A. The diaphragm helps in digestion by secreting digestive enzymes
B. The diaphragm has no role in the mechanism of breathing
C. The diaphragm helps in the process of inhalation and exhalation by changing the volume of the chest cavity.
D. The diaphragm only helps in exhalation and not in inhalation

D. H2O + CO2 -> C6H12O6 + 6O2
Explain the gas exchange mechanism in humans.
A. Gas exchange happens in the skin, allowing for breathing through pores.
B. Oxygen is released from the blood in the kidneys and carbon dioxide is absorbed.
C. Gas exchange in humans occurs in the alveoli of the lungs, where oxygen is absorbed into the blood and carbon dioxide is released.
D. Gas exchange occurs in the stomach where nutrients are absorbed.

A. Lungs
B. Stomach
C. Kidneys
D. Liver
What is the difference between external and internal respiration?
A. External respiration is the process of digestion; internal respiration is the exchange of nutrients.
B. External respiration occurs in the lungs; internal respiration occurs in body tissues.
C. External respiration happens during exercise; internal respiration occurs at rest.
D. External respiration occurs in the heart; internal respiration occurs in the lungs.
What is the significance of carbon dioxide in respiration?
A. Carbon dioxide is a waste product that has no role in respiration.
B. Carbon dioxide is used to create energy in the form of ATP.
C. Carbon dioxide is only produced during exercise and not at rest.
