Respiratory system

Disease of the Respiratory System *Emphysema: Inhaled toxic vapors, such as those found in cigarettes smoke, can lead to the development of emphysema, an irreversible disease, that jeopardizes( destroy)the lungs´ability to function. The walls of the Alveoli get destroy so exchange cant happen.The gas exchange is reduce.The ones with emphysema needs to breath faster than the normals because they are not receiving.* Pneumonia: Is an infection/inflammation cause pus in the lungs.Five main causes of pneumonia are; bacteria,viruses,mycoplasmas, fungi, including pneumocystis, chemicals.*Bronchitis: The inflammation of the bronchiole cause by bacteria, viruses, smoking, inhalation of chemical pollutions or dust. The cilia stops working.*Asthma: The walls of the bronchiole gets inflammation/ swollen closing the airways.Asthma gets to; tobacco smoke, allergies, catching a cold.During asthma flare-ups it happens; inflammation, mucus, bronchoconstriction.The inhaler( medication) helps to desinflate the wall of the bronchiole.

Nose:-warms, moistens and filters the air. -The air gets into your body by the nose. -The openings of the nose are called nostrils-The air that you breath is cold but when it gets in it will be heated by the warm blood that flows through the vessels. -Mucus in the nose moistures the air.

Pharynx:-Passageway that leads to the trachea.-Common name throat.-Muscle tube about 5 inches long.-connects the nasal cavity with the trachea-it is lined with cilia that trap dirt that might gotten past the filtering system in the nasal cavity.

Trachea:-Common name wind pipe-about 12 inches long-made up of rings of cartilage-if the epiglottis is open air passes from the pharynx to the trachea.-as the air moves down cilia trap dust particles and bacteria-like the nose the trachea produces tiny explosions in respond to irritation, the explosions are called coughs, during the coughs air is expelled at a speed 160 km per hour.

Alveoli :-the functional unit of the respiratory system. This is where the oxygen and the carbon dioxide are exchange, oxygen enters the blood carbon dioxide is removed from the blood.

Bronchi:The tiny branches of air tubes within the lungs which are the continuation of bronchi and connect to the alveoli

Bronchioles:The small airways of the lung extending from the bronchi to the alveoli.

Lungs:oxygen from the air into the blood and removing carbon dioxide from the blood.

Diaphragm:Diaphragm goes down it inhale, and when it goes up it exhale.


Larynx:-Common name voice box-series of folds of tissues surrounded by protective cartilage called vocal cords.-when air passes through the vocal cords sound is made. you control the amount of air passing through the larynx.

Protection in the nose: * inside your nose there is mucus and tiny hairs called cilia, they will trap all the dust, small particles and bacteria that might enter through your nose. -if there is dust particles or bacteria the nose will produce a small explosion to take them out (sneezing).


The Function of the Respiratory System is responsible for getting oxygen into the body and removing carbon dioxide and water.
