Document Summary

Anatomy: respiration- ventilation of lungs (breathing) or use of o2 in cellular metabolism, takes in o2 and breathes out co2, functions. Lamina propria contains large blood vessels that help warm the air and populated by lymphocytes and plasma cells: erectile tissue- every hour, the tissue on one side swells and restricts airflow so the air flow sifts between nostrils. Pharynx: muscular funnel extending to larynx, nasopharynx. Space between posterior margin of soft palate and epiglottis. Pass air, food, and drink: muscles play necessary roles in swallowing and speech. Intrinsic muscles control the vocal cords by pulling on the corniculate and arytenoid cartilages, causing the cartilages to pivot, depending on the direction, the vibration is different and creates a different pitch. In males, vocal cords are longer and thicker and vibrate more slowly. Loudness is determined by the force of air passing between vocal cords: sound of larynx are formed into words by the pharynx, oral cavity, tongue, and lips.
