Respiratory System

• Group of tissues and organs that allows you to breathe. 

• The organs that help to get oxygen from air to your blood and get rid of carbon dioxide, makeup the respiratory system.

Larynx/ Voice box

• Your larynx is a hollow tube that connects your throat (pharynx) to the rest of your respiratory system.

• It helps you swallow safely and contains the vocal cords, so it's often called the voice box

Trachea

Wind pipe

Extends from Larynx to the middle of thoracic cavity where it divides into bronchi 

Bronchus

• plural: bronchi

• Formed by division of trachea.

• Subdivide into smaller and smaller branches, bronchioles

Alveoli

• Alveolus – individual sac

• Bunches of tiny air sacs inside the lungs.

• When you breath in, they fill with air.

• Very thin walls which permit the exchange of gases (oxygen and carbon dioxide)

• Exchange oxygen and carbon dioxide in the blood stream.

Lungs

• Soft spongy elastic organs with smooth shiny surface.

• Consists of bronchioles, alveoli and an extensive network of blood vessels and the capillaries.

Diaphragm

The diaphragm, located below the lungs, is the major muscle of respiration.

It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily.

Works with lungs to inhale and exhale air.
