1. Respiratory System RaelynnLlemit 8-14

2. Respiratory System Breathing System Takes in oxygen Breathes out carbon dioxide

3. Trachea Windpipe Leads passage from the throat to lungs Inhales air from Larynx to Bronchi

4. Larynx “Voice Box” Produce sound Air breathed in and out

5. Bronchus Two main branches of the Trachea Air passages beyond the Trachea Carries air to the lungs

6. Lungs Air-breathing vertebrates Serves carbon dioxide to the atmosphere Provides oxygen to the blood

7. Alveolus Tiny air sacs for holding air in the lungs Gas exchange takes place Help from the Circulatory System

8. Diaphragm Main muscle for breathing Expands reducing amount of air breathed in to breathe out Expands when the air was pulled to the lungs

9. Bronchioles First airway branches Carries air to the Alveolus Main passage way (lungs)
