Certainly! Below is a table that outlines the structure and function of each part of the respiratory system you requested:
| Part | Structure | Function | |-------------|---------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------| | NOSE | The nose has external nostrils (nares) and a nasal cavity lined with mucous membranes and tiny hairs (cilia). | The nose filters, warms, and humidifies incoming air; it also houses olfactory receptors for smell. | | PHARYNX | The pharynx is a muscular tube extending from the nasal cavity to the larynx, consisting of three sections: nasopharynx, oropharynx, and laryngopharynx. | It serves as a passageway for air and food, and it plays a role in vocalization and immune function. | | LARYNX | The larynx is made of cartilage and contains the vocal cords, which are folds of tissue that can open and close. | It acts as a voice box, producing sound; it also protects the trachea against food aspiration. | | TRACHEA | The trachea is a flexible tube lined with ciliated mucosa and C-shaped cartilage rings. | It provides a clear airway for air to enter and exit the lungs; it also traps and expels debris. | | EPIGLOTTIS | The epiglottis is a flap of cartilage that sits at the base of the tongue. | It prevents food and liquid from entering the trachea during swallowing by covering it. | | BRONCHI | The bronchi are two main air passages (right and left) branching from the trachea, containing cartilage and smooth muscle. | They transport air from the trachea to the lungs; they further branch into smaller bronchi and bronchioles. | | BRONCHIOLES | Bronchioles are small, branching tubes composed of smooth muscle and lack cartilage. | They regulate airflow to the alveoli through constriction and dilation and facilitate gas exchange. | | ALVEOLI | Alveoli are tiny air sacs at the end of bronchioles surrounded by capillaries; they have thin walls. | They are the primary sites for gas exchange (O2 and CO2) between air and blood. |
