rings complete or C-shaped? Why is this important?

Learning Outcomes 1. Identify the larynx, trachea, lungs, heart, aorta, pulmonary artery, pulmonary vein, and venae cavae on a sheep pluck. 2. Demonstrate lung inflation in a sheep pluck.

Materials Needed □ □ □ □

Fresh or preserved sheep pluck Source of compressed air and an air hose Dissecting tray Disposable gloves

Instructions A sheep pluck includes the larynx, trachea, lungs, heart, and parts of the major blood vessels (aorta, pulmonary artery,

4. Identify the carina, the right primary bronchus, and the left primary bronchus. Carina - Also known as the tracheal carina. The apertures of the right and left main bronchi are separated by a ridge at the base of the trachea. Right primary bronchus - The right primary bronchus is wider, shorter than the left main bronchus, which is thinner and longer. Left primary bronchus – It is a narrow, long passageway into your left lung. 5. Identify the visceral pleura. What is the function of this serous membrane? The visceral pleura covers the surface of the lungs. A pleura is a serous membrane that folds back on itself to form a two-layered membranous pleural sac.

6. Demonstrate lung function by inserting a hose from an air compressor into the trachea and forcing air into the lungs. What happens? 7. Stop forcing air into the lungs.
