Copy of Respiratory System
Transcript of Copy of Respiratory System
The respiratory system is a group of tissues and organs that supply blood and oxygen to the different parts of your
body. The body inhales oxygen and exhales carbon dioxide.
The Major Parts of the system
Mouth and Nose
Bronchi and Bronchial Tubes
Did you known that the throat is
divided into three regions: the nasopharynx, oropharynx, and larygophaynx.
The diaphragm is the major abdominal muscle that is involved in the breathing process. The surrounding muscles support the diaphragm in its actions. When at rest, the diahragm forms a high arched dome. When it contracts the dome descends increasing the height of the chest cavity resulting in air being drawn into the lungs.
Provides a clear way for air to enter and exit lungs.
Bronchi is the branches of the passages of the respiratory system that lead from the trachea into the lungs.
The larynx is also known as the voice box and its located in the neck.
Diseases of the Lung :
Like all other systems there are many diseases related to the respiratory system. Some of the most common diseases are bronchitis, asthma and tuberculosis.
The lungs are the main part of the respiratory system which enables the exchange of oxygen and carbon dioxide in the blood.
Lungs are dense networks of connected tubes that transport oxygen from air to nourish the trillions of cells in our body.

Tiny hairs in the nose trap unwanted particles while a sticky liquid called mucus catches many of the germs before they all can go too far into the respiratory system. The mucus also warms and moistens the air.
Air enters the body through either the open mouth or the nose. It travels down the trachea to the lungs, where the oxygen in it passes into the bloodstream.
Alveoli is tiny, grape-like sacs in the lungs where the exchange of oxygen and carbon dioxide occurs
The oxygen exchange inthelungs takes place accross the membrances of small balloon-like sturctures calle dalveoli attached to the branches of the bronchial passages. These alveoli inflate and deflate with inhalation and exhalation.
There are two Bronchial Tubes in the Human Body which are right and left located in the lungs .
The Trachea, also known as the windpipe, allows air to flow into two hollow branches called the Bronchi or Bronchial Tubes.
The epiglotis is a flap-like projection, covered by a mucus membrane, which sits on top of the larynex. The Epiglotis has a core of elastic cartilage and numerous mix glands are found in the lamina proporia on the laryngeal side. It acts as a switch between trachea and esophagus and covers larynx while swallowing. The muscular flap prevents food from going into the lungs.
