• Lungs are the organs responsible for gas exchange with the bloodstream.
• Bronchial tubes are the two main branches that carry air into the lungs.

• The trachea is the windpipe, which carries air from the larynx to the bronchi.

• Lungs are the organs responsible for gas exchange with the bloodstream.
• Tracheal rings support the walls of the trachea.
• The lungs have two lobes, the right lung has three lobes while the left lung has only one lobe to accommodate the heart.
• Tracheal rings support the walls of the trachea and prevent it from collapsing during breathing.
• The trachea is also known as the windpipe, which carries air from the larynx to the bronchi.
• Tracheal rings support the walls of the trachea and prevent it from collapsing during breathing.
• The bronchioles branch off from the bronchial tubes, leading to smaller and smaller passages until they reach the alveoli.
• Each lung is divided into segments by connective tissue septa that contain bronchioles and arteries.
• Cilia are tiny hair-like projections on the surface of cells that move back and forth to sweep away mucus and debris.
• Tracheal cartilage forms rings around the trachea to keep it open during breathing.
• Cilia are hair-like projections on cells that line the respiratory tract.
• Cilia are hair-like projections on cells that line the respiratory tract.
• The pleural membrane covers the surface of the lungs and lines the thoracic cavity.
• Mucous glands produce mucus, which helps trap foreign particles and bacteria in the respiratory tract.
• Alveoli are tiny sac-like structures where oxygen diffuses into the bloodstream and carbon dioxide diffuses out.
• Capillaries surround the alveoli and transport oxygenated blood away from the lungs.

• The diaphragm is a sheet of muscle located at the bottom of the ribcage that contracts and relaxes to aid in breathing.
• Bronchioles are small tubes that branch off from bronchi and lead to alveoli.

• The diaphragm is a sheet of muscle located at the bottom of the ribcage that contracts and relaxes to aid in breathing.
• Alveolar ducts lead to clusters of alveoli where gas exchange occurs between air and blood.
• Alveoli are tiny sac-like structures found at the end of the respiratory tract where oxygen diffuses into the bloodstream and carbon dioxide diffuses out.
• Mucous glands produce sticky secretions called mucus.
• Pulmonary capillaries surround the alveoli and exchange oxygen and carbon dioxide with the bloodstream.
• Gas exchange occurs at the level of the alveoli, where oxygen diffuses into the bloodstream and carbon dioxide diffuses out.
