Answer:Here's a simplified explanation of the respiratory system's parts and their functions: - Nose/Mouth: Warm, filter, and moisten air.- Pharynx (throat): Passageway for air and food.- Larynx (voice box): Voice production; protects airway.- Trachea (windpipe): Carries air to lungs.- Bronchi/Bronchioles: Air passages branching into lungs.- Lungs: Main organs; gas exchange happens here.- Alveoli (air sacs): Tiny sacs where oxygen enters blood, carbon dioxide leaves.- Diaphragm: Muscle that helps you breathe.
