definition of all respiratory parts and it's function/roles
Answer (1)
Answer:The respiratory system's main function is gas exchange: taking in oxygen and releasing carbon dioxide. Here's a simplified look at its parts and roles: Upper Respiratory Tract: - Nose/Mouth: Air entry points; nose warms, filters, and humidifies air.- Nasal Cavity: Filters and warms incoming air.- Sinuses: Hollow spaces that regulate air temperature and humidity.- Pharynx (Throat): Passageway for air and food.- Larynx (Voice Box): Contains vocal cords for sound production.- Epiglottis: Flap that prevents food from entering the airway. Lower Respiratory Tract: - Trachea (Windpipe): Tube carrying air to the lungs.- Bronchi: Two large tubes branching from the trachea, leading to each lung.- Bronchioles: Smaller branches of the bronchi.- Alveoli: Tiny air sacs in the lungs where gas exchange occurs (oxygen enters blood, carbon dioxide leaves).- Lungs: Main organs of respiration; contain alveoli and blood vessels for gas exchange.- Diaphragm: Muscle that helps control breathing; contracts to inhale, relaxes to exhale.- Rib Cage: Protects the lungs.
