This document provides an overview of Activity #11 which focuses on the respiratory and digestive systems. The objectives are to identify structures of the respiratory system through models, cadavers, and histology slides as well as structures of the digestive system through models, cadavers, and histology slides. The document then outlines the major components and structures of both the upper and lower respiratory tract as well as the major organs of the digestive system. Diagrams and figures are referenced throughout to illustrate key structures and concepts.

1. 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.

2. Gross Anatomy of Respiratory System

The major components of the respiratory system are organized into
upper and lower respiratory tracts.
Upper Respiratory Tract
• Paranasal sinuses
• Nasal cavity
• Pharynx
Lower Respiratory Tract
• Larynx
• Trachea
• Bronchi
• Lungs
• Diaphragm muscle
