The Respiratory System Respiratory System
The respiratory system is used to exchange gases between the human body and its environment. Internally, it helps exchange oxygen with the carbondioxide in the blood. Respiratory System
The major organ involved in respiration is the lungs. \Every animal, with the exception of fish, have two lungs. Respiratory System

How Does The Respiratory System Work? Respiratory System
The Nose Air (oxygen) is breathed in through the nose. Nose hairs help keep out unwanted particles. Respiratory System
Unwanted Particles Oxygen Respiratory System

The walls inside the nose are lined with membranes containing two types of cells. Some are ciliated while others produce mucous. Respiratory System

Together , the mucous and cilia prevent most dust and other particles from traveling any farther. Respiratory System

The mucous is wet and sticky which helps it moisten the air. Respiratory System
The mucous is wet and sticky which helps it moisten the air. Respiratory System
As the air travels through the nasal passages, it is warmed by the capillaries running nearby. Respiratory System

Thus, the nose helps clean, moisten, and warm the air in the beginning of the process. Respiratory System
Pharynx Larynx Respiratory System
The pharynx runs from behind the nasal passages and mouth to just above the larynx Pharynx Larynx Respiratory System
Pharynx Larynx The pharynx is part of both the respiratory and the digestive systems. It is the throat. Respiratory System
After the oxygen passes through the pharynx, it enters the larynx. The larynx is also wherethe voice box is located. Pharynx Larynx Respiratory System
Trachea The larynx is followed by the trachea. Respiratory System
The trachea is about 12 centimeters long and it is lined by bands of cartilage for support. Respiratory System

Ciliated goblet cells The trachea, like the nasal passages, have cilia lined mucous membranes. Respiratory System
Ciliated goblet cells The cilia help to remove harmful particles from the trachea. Respiratory System
Ciliated goblet cells If food unintentionally falls into the trachea, the cilia help bring it back up to the pharynx. Respiratory System
Bronchi and Bronchioles Respiratory System
Bronchi and Bronchioles The bronchi are two cartilage banded tubes that branch out from the trachea. Each bronchi enters one of the lungs. Respiratory System

BronchiandBronchioles The bronchi are two cartilage banded tubes that branch out from the trachea. Each bronchi enters one of the lungs. Respiratory System
Bronchiand Bronchioles The two bronchi, themselves divide into even smaller sets of tubes called the bronchial tubes. Respiratory System
Bronchiand Bronchioles The two bronchi, themselves divide into even smaller sets of tubes called the bronchial tubes. Respiratory System
Bronchiand Bronchioles The bronchial tubes lose cartilage and the walls become thinner as the tubes branch. Respiratory System
