1 IPHY 3410 (Saul): HUMAN ANATOMY Fall 2023 Homework #10 DUE: November 6, 2023, 11:59 PM 1. Respiration consists of four processes. Identify which process is occurring in each of the following descriptions. (Choices: Internal respiration, external respiration, ventilation, gas transport in blood.) (0.75 pt) Oxygen diffuses from blood, across the blood vessel wall, into a nerve cell Carbon dioxide is carried in the blood from the heart to the lungs Air moves from the nostrils to the pharynx Carbon dioxide diffuses into the blood from a muscle cell that is located in a blood vessel wall Air travels upward from the lungs to the atmosphere Oxygen diffuses from the air, across the wall of a pulmonary alveolus, into the blood 2. What type of epithelium is found in each of the following regions of the respiratory mucosa? (Choices: Nonciliated simple columnar, pseudostratified ciliated columnar, simple squamous, keratinized stratified squamous, nonkeratinized stratified squamous). (0.75 pt) Nasal cavity Nasopharynx Oropharynx Laryngopharynx Regions of the conducting zone that are often exposed to food Most regions of the conducting zone that are NOT exposed to food 3. The adenoids are tonsils located in the nasopharynx. These can become enlarged in children. If the nasopharynx becomes completely blocked, then to reach the lungs, air will have to travel through, in order: (0.25 pt) a. Nasal cavity, oropharynx, laryngopharynx, larynx b. Oral cavity, oropharynx, esophagus, laryngopharynx, larynx c. Oral cavity, nasopharynx, oropharynx, laryngopharynx, larynx d. Oral cavity, oropharynx, laryngopharynx, larynx 4. Identify the laryngeal cartilage matching each of the following descriptions. (Choices: Arytenoid cartilage, cricoid cartilage, epiglottis, thyroid cartilage.) (1 pt) Elastic cartilage that folds down to prevent food from entering larynx Anterior attachment of the vocal folds Posterior attachment of the vocal folds Articulates directly with the thyroid cartilage, and moves around this articulation in the sagittal plane in order to speak in a higher pitch The most inferior of the laryngeal cartilages More prominent in adult males, resulting in a deeper voice Rotates from side to side in order to open and close the rima glottidis wynn oh Th Gas trans ventilation Internal res External respiration Pseudo stratified abated columnar Pseudo stratifiedabated columnar Non keratinized stratified squamous non keratinized stashed squamous stratified squamous Pseudo stratified c Gated columnar III a epiglottis Arytenoid cricoid thyroid arytenoid
