Respiration: body obtains and uses oxygen and removes carbon dioxide & water.

Two parts to respiration:

1. Breathing:

   a. Inhalation: contraction – muscle moves down / lungs expand

   b. Exhalation: air moves out automatically

2. Cellular respiration: chemical reaction that uses oxygen to release energy from food

What is respiration?

Respiration is the process by which organisms take the oxygen from the external environment and expel the carbon dioxide in the opposite direction, which produces energy and other side output such as water.

Actually, there are three types of respiration:

1. Breathing or external respiration: a mechanical process to take the oxygen into our body and expel the carbon dioxide to the environment. This process includes:

       a. Inhalation: diaphragm muscle contracts (moves down), lungs expand and air move in

       b. Exhalation: diaphragm muscle relaxes and air move out

2. Internal respiration: an exchange process between gases in the blood and body cells.

3. Cellular respiration: a metabolic/chemical process that extracts energy from food by using oxygen. It produces carbon dioxide and water as well.
