Unformatted text preview: BI 233 Laboratory Objectives Anatomy of the Respiratory System Exercise 36 You should be able to recognize, identify, and provide a concise definition for each of the following terms, structures, and concepts. You should be able to apply them to appropriate specimens, models, charts, diagrams, prepared microscope slides, and computer simulations. Be sure to complete the objectives at the beginning of each lab. NOTE: YOU WILL NEED TO USE FIGURES FROM THE DIGESTIVE SYSTEM LAB (Exercise 38) AND YOUR TEXTBOOK (Chapter 24) FOR THIS WEEKS LAB By the end of todays lab you should be able to: Define the following terms: respiratory system, pulmonary ventilation, external respiration, and internal respiration. Label the major respiratory system structures on a diagram/model and to describe the function of each. List the structures, in order, that air must pass through to reach the alveoli in the lungs. (begin with nasal cavity) Describe the changes to the mucosa and cartilage structures of the respiratory system as they pass from nasal cavity to larynx, to trachea, and through the bronchial tree. Recognize the histologic structure of the trachea (c.s.) and lung tissue on prepared slides, and to describe the functions of the observed structural modifications. I. Introduction Define the following terms: a. Cellular respiration b. Respiratory system c. Respiration d. Pulmonary ventilation e. External respiration f. Transport of respiratory gases g. Internal respiration - 1 - Complete Activity 1: Identifying Respiratory System Organs II. Upper Respiratory System Structures a. External nares (this is mislabeled in some printings of the lab manuals) b. Nasal cavity i. Vestibule ii. Nasal septum iii. Inferior nasal conchae and meatus iv. Middle nasal conchae and meatus v. Superior nasal conchae and meatus vi. Paranasal sinuses (identify these on skull models) vii. Hard palate viii. Soft palate ix. Cleft palate (be able to define) c. Pharynx (13 cm, 5 in) i. Nasopharynx 1. internal nares (posterior nasal aperature) 2. openings of auditory (pharyngotympanic) tubes 3. otitis media (define only) 4. pharyngeal tonsils (adenoids) ii. oropharynx 1. palatine tonsils 2. lingual tonsils 3. fauces: opening to oral cavity 4. uvula- 2 - iii. laryngopharynx d. larynx i. thyroid cartilage ii. cricoid cartilage iii. epiglottis iv. arytenoid cartilage v. corniculate cartilage vi. cuneiform cartilage vii. vestibular folds (false vocal cords) viii. vocal folds (true vocal cords) ix. glottis x. thyroihyoid membrane xi. cricotracheal ligament xii. cricothyroid ligament xiii. laryngeal prominence xiv. hyoid bone ` III. Lower Respiratory System Structures: For each of the following structures, know which are part of the respiratory zone and which are part of the conducting zone a. Trachea (12 cm, 5 inches long x 2.5 cm, 1 in diameter) i. C-shaped rings (15-20) 1. understand structural relationship to esophagus ii. Trachealis muscle b. carina c. Primary (main) bronchi (1 to each lung) d. Hilus - 3 - e.e....
