Respiratory+System

===The Respiratory system is the system in which oxygen is taken in and carbon dioxide is given out. It consist of the Nose, Epiglottis, Pharynx, Larynx, Trachea, Bronchi, Bronchioles and last but not least the Lungs. The Nose contains the nostrils and it is used fro breathing aswell as smelling different scents. Epiglottis is a flap of cartilage at the root of the tongue. It is depressed during swallong, covering the opening of the windpipe. Pharynx is a passegeway for air and food. The lower part allows only air, food, and fluids to pass by. While the upper part only allows food to pass by. Larynx is an airway passage to the lungs as well as providing vocalization. It is also known as the sound box. The Trachea connects the Pharynx or the Larynx to the Lungs and allows air to pass to the lungs. Bronchi are airway tubes that carry air into and out of the Lungs. Bronchioles are the brancehes of the Bronchi. The Bronchioles terminate by entering the circular sacs which are called Alveoli. Finally, the Lungs. Lungs are pumps that pull Oxygen in and absorb the Oxygen into the lining of the Lungs, then it pushes the Oxygen into the chambers of the heart, this will make it possible for the Oxygen to travel to the rest of the body.===
