Explanation:

• Internal respiration refers to the gas exchange between the blood and the body's tissues, not within the lungs.
• Breathing is the process of inhaling and exhaling air, which is a mechanical process and not specifically the exchange of oxygen within the lungs.

• External respiration is the exchange of oxygen and carbon dioxide between the alveoli in the lungs and the blood in the pulmonary capillaries.
