Respiration The respiratory system brings air rich in oxygen into the body and gets rid of air rich in carbon dioxide.
Function of the Respiratory System To bring about the exchange of oxygen and carbon dioxide between the air, the blood, and the tissues.
Lesson 3 The Respiratory System Your lungs and chest expand like a balloon as you inhale. As you exhale, your lungs deflate slightly.
Respiratory System Breathing Is the movement of air into and out of the lungs Allows your respiratory system to take in oxygen and eliminate carbon.

RESPIRATORY SYSTEM. I. Function – to take in oxygen & get rid of carbon dioxide (for cell respiration) A. Respiration = internal (cell) + external (breathing)
Oxygen carbon dioxide The respiratory system is the system of the body that deals with breathing. When we breath, the body takes in the oxygen it needs.
 The respiratory system uses many parts for breathing in oxygen and releasing carbon dioxide.  These include the nose, the trachea, and the lungs.
Functions of the Respiratory System Brings oxygen in from the environment for our body cells, and removes carbon dioxide waste. Main components: – Nose.

Before we answer the next question… Recall the Breathing Process Demonstration!

What happens in your lungs when… Pressure (Chest cavity) Volume (in Lungs) Air Movement Decreases Increases Moves In Increases Decreases Moves Out During inhalation, rubber sheeting (diaphragm) is pulled down (expands), air pressure decreases, volume increases, and air moves in. Chest cavity Lungs Trachea Bronchi Diaphragm

Rubber sheeting (diaphragm) is pulled down (contracting)  balloons (lungs) inflate because pressure decreases and volume increases, forcing air to flow in (inhale) Rubber sheeting (diaphragm) pushed in (relaxing)  balloons (lungs) deflate because pressure increases, volume decreases and air is forces out (exhale)

Moistens, warms and filters the air Pharynx Larynx Trachea Bronchi Bronchioles Exchange of oxygen and carbon dioxide with blood
