What are the main organs of the respiratory system?

• Kidneys

• Liver

• Stomach

• Lungs, trachea, bronchi, diaphragm, bronchioles

Explain the process of gas exchange in the lungs.

• Gas exchange occurs in the stomach through absorption

• Gas exchange in the lungs occurs in the alveoli through diffusion, where oxygen is taken into the bloodstream and carbon dioxide is released into the air.

• The process of gas exchange in the lungs involves filtration

• Oxygen is released into the air and carbon dioxide is taken into the bloodstream

Describe the structure of the lungs and how it relates to their function.

• Lungs are filled with blood vessels to transport oxygen and nutrients.

• The lungs are made up of muscles and bones, allowing for movement and support.

• The structure of the lungs includes the heart, which pumps blood to oxygenate it.

• The lungs consist of bronchi, bronchioles, and alveoli, which provide a large surface area for gas exchange and efficient respiration.

What is the role of alveoli in the respiratory system?

• Alveoli facilitate gas exchange in the respiratory system.

• Alveoli store oxygen in the respiratory system.

• Alveoli regulate blood flow in the respiratory system.
