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

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

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.

The mucous is wet and sticky which helps it moisten the air.

As the air travels through the nasal passages, it is warmed by the capillaries running nearby.

Thus, the nose helps clean, moisten, and warm the air
in the beginning of the process.
Respiratory System
Pharynx
Larynx
Respiratory System
PharynxLarynx
The pharynx runs from behind the nasal passages and mouth to just above the larynx
Respiratory System
PharynxLarynx
The pharynx is part of both the respiratory and the digestive systems. It is the throat.
Respiratory System
PharynxLarynx
After the oxygen passes through the pharynx, it enters the larynx. The larynx is also where the voice box is located.
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.

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
The bronchi are two cartilage banded tubes
that branch out from the trachea. Each bronchi
enters one of the lungs.

The bronchi are two cartilage banded tubes

Bronchi and

The two bronchi, themselves divide into
even smaller sets of tubes called the
bronchial tubes.

Bronchi and

The bronchial tubes lose cartilage and the walls become thinner as the
tubes branch.

Respiratory System
Bronchi and
Bronchioles
The bronchial tubes branch into bronchioles.

Bronchi and
Bronchioles
Bronchioles have thin walls without much
cartilage bands.

Alveoli
Alveoli are air sacs inside the lungs. Many alveoli are
bunched together like grapes at the end of each bronchiole.
Respiratory System
Alveoli
Alveoli make up most of the lung space. The alveoli are
surrounded by many capillaries.
Respiratory System
Alveoli
The capillaries carry carbon dioxide. The alveoli carry oxygen. The alveoli's thin respiratory surface allows
diffusion to occur.
Respiratory System
Alveoli
The carbon dioxide and oxygen exchange. The carbon dioxide,
which is now in the alveoli, leaves the body.

The oxygen is now in the blood and can be used.
