Activity #11: Respiratory and Digestive Systems Chapter 25 & 26 – McKinley et al., Human Anatomy, 4e. Objectives: Identify structures listed in the gross anatomy of the respiratory system on models and cadavers. Histology: Examine a slide or photo of lung tissue and identify indicated structures. Identify structures listed in the gross anatomy of the digestive system on models and cadavers At home assignment: Identify histology slides and structures from various digestive system histology slides or photos. Compilation: Lisa Radmall
