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.

Gross Anatomy of Respiratory System

2

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 muscleFig. 25.1
