12 types of respiratory system starting with nose
Answer (1)
It seems like you're asking for a list of 12 different parts of the respiratory system, starting with the nose. Here's a breakdown: 1. Nose: The entry point for air, filtering and warming it. 2. Nasal Cavity: The space within the nose, lined with mucous membranes that trap particles. 3. Pharynx: The throat, a passageway for both air and food. 4. Epiglottis: A flap of cartilage that covers the trachea (windpipe) during swallowing, preventing food from entering the lungs. 5. Larynx: The voice box, containing vocal cords that vibrate to produce sound. 6. Trachea: The windpipe, a tube that carries air to the lungs. 7. Bronchi: Two branches that extend from the trachea, leading to the lungs. 8. Bronchioles: Smaller branches that extend from the bronchi, carrying air to the alveoli. 9. Alveoli: Tiny air sacs in the lungs where gas exchange (oxygen in, carbon dioxide out) occurs. 10. Lungs: The primary organs of respiration, containing the bronchi, bronchioles, and alveoli. 11. Diaphragm: A dome-shaped muscle that separates the chest cavity from the abdomen. It contracts and relaxes to help with breathing. 12. Intercostal Muscles: Muscles between the ribs that also assist in breathing.
