Respiratory System

Raelynn Llemit8-14

Respiratory System

Breathing System

Takes in oxygen

Breathes out carbon dioxide

Trachea

Windpipe

Leads passage from the throat to lungs

Inhales air from Larynx to Bronchi

Larynx

“Voice Box”

Produce sound

Air breathed in and out

Bronchus

Two main branches of the Trachea

Air passages beyond the Trachea

Carries air to the lungs

Lungs

Air-breathing vertebrates

Serves carbon dioxide to the atmosphere

Provides oxygen to the blood

Alveolus

Tiny air sacs for holding air in the lungs

Gas exchange takes place

Help from the Circulatory System

Diaphragm

Main muscle for breathing

Expands reducing amount of air breathed in to breathe out

Expands when the air was pulled to the lungs

Bronchioles

First airway branches

Carries air to the Alveolus

Main passage way (lungs)
