1. Trachea: - Where it belongs: It is part of the respiratory system and connects the throat (pharynx) to the lungs. - Function: It acts as a passage for air to enter and exit the lungs.2. Bronchi: - Where it belongs: Branching off from the trachea, the bronchi are also part of the respiratory system. - Function: The trachea divides into two main bronchi (right and left), which carry air into each lung.3. Bronchioles: - Where it belongs: These are smaller branches of the bronchi located within the lungs. - Function: They further divide into smaller airways, allowing air to flow into the alveoli.4. Alveoli: - Where it belongs: Located at the end of the bronchioles within the lungs. - Function: Tiny air sacs where gas exchange occurs; oxygen enters the blood, and carbon dioxide is expelled.5. Lobes: - Where it belongs: The lungs are divided into lobes (three in the right lung and two in the left). - Function: Each lobe contains bronchi, bronchioles, and alveoli, working together for gas exchange.6. Pleura: - Where it belongs: A membrane surrounding each lung. - Function: Provides lubrication and reduces friction during breathing.7. Diaphragm: - Where it belongs: Although not part of the lungs themselves, it is a muscle located beneath the lungs. - Function: Plays a crucial role in breathing by contracting and relaxing to help inflate and deflate the lungs.
