Hi our names are Gabby Dumene and Yostina Barsy we have been shrink and we're taking a trip to the respiratory system. We're going to show you some organs and the importance of the respiratory system.

The human Respiratory system is a series of organ responsible for taking in oxygen and get rid of carbon dioxide. In other words your respiratory system is the system that helps you breathe.

The organs that are involved in the respiratory system are the nose, pharynx, trachea, bronchi and lungs. They all have they're own function and work together to make the Respiratory System work.

First to inhale oxygen enters the body through the nose. Then get transfers to the pharynx or throat. Then from the pharynx it get transfer to the trachea or windpipe. So from the trachea it goes to the left and right bronchi. Then the oxygen get transferred to the lungs. And the lungs allow the oxygen to be taken into the body and get rid of carbon dioxide. And when you exhale your muscle in your chest relaxes.

Your respiratory system moves air containing oxygen into your lungs and moves carbon dioxide and water from your body. Your lungs and the structures that lead to them make up your respiratory system.

Inhale

Exhale

while we were watching the person breathe, his rib muscles and diaphragm contract. As a result, his chest expands and inhale. When these muscles relax, his chest contracts and exhale. As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
