Dissection of the Fetal Pig Respiratory System DISSECTION EXERCISE P7 LEARNING OUTCOMES These Learning Outcomes correspond by number to the laboratory activities in this exercise. When you complete the activities, you should be able to: Activity P7.1 Describe the structure and function of fetal pig respiratory organs in the head and neck and make comparisons with similar organs in the human. Activity P7.2 Describe the structure and function of the fetal pig lungs and make comparisons with human lungs. LABORATORY SUPPLIES Preserved fetal pigs Dissecting equipment: trays, tools, gloves Protective eyewear Face mask Hand lens or dissecting microscope Anatomical models of the human respiratory system PRE-LAB QUIZ Before you begin, read all the activities in Exercise P7 and the required reading in your textbook that is assigned by your instructor. 1. During this fetal pig dissection exercise, you will examine all the following structures except the a. external nares. b. diaphragm. c. thyroid cartilage. d. oral cavity. e. true vocal cords. 2. True or False: The tracheal wall contains a series of C-shaped cartilaginous rings, but the esophageal wall does not. 3. True or False: In the fetal pig, the right lung has three lobes, and the left lung has four lobes. Questions 4-10: Match the structure in column A with the correct description in column B. A 4. Pulmonary arteries 5. Pulmonary veins 6. Diaphragm 7. Cricoid cartilage 8. True vocal cords 9. Esophagus 10. Parietal pleura B a. The glottis is the space between these structures. b. This structure travels dorsal to the trachea. c. This structure covers the wall of the thoracic cavity. d. This blood vessel transports oxygen-rich blood. e. This structure forms a portion of the wall of the larynx. f. This blood vessel transports oxygen-poor blood. g. This structure separates the thoracic and abdominal cavities.
