10. Branch of Pulmonary Artery & Vein
Remove a piece of lung tissue (from anywhere!) and search for a branch

12. Branch of Pulmonary Vein

13. Bronchiole
Search through the piece of cat lung that you just removed and check for an empty duct with
white walls. This
would be a branch of the bronchus - a bronchiole!

The left phrenic nerve is embedded in the pleural folds that
lead to the diaphragm.

25. Thymus Gland

26. HAP Coloring
•Color the arterial system of the cat red to receive 10 points.
•Color the venous system of the cat blue to receive 10 points.
•The coloring sheets are in your dissection instructions.
