The Little Guide To Our Respiratory System

The Little Guide To Our Respiratory System
The Respiratory System is the set of these body organs: mouth, nose, trachea, lungs, and diaphragm which leads the process of the Respiratory system.

Its main functions is to supply oxygen to the blood so that the oxygen can be delivered to all the parts of the body along with the blood.

Respiratory system exchanges the Oxygen with the carbon dioxide. That is the process where we inhale Oxygen through our nose or the mouth and exhale the carbon dioxide.

1. Oxygen enters the respiratory system through the mouth and the nose.

2. First the Air passes into the nostrils where it is filtered by the nasal hairs and warmed and humidified in the nasal cavity and sinuses, then the air passes through the pharynx, which is shared with the digestive tract.


3. Then the oxygen goes through the larynx (is the organ where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. The larynx is situated at the top end of the trachea.

4. In the chest cavity, the trachea splits into two smaller tubes which are called the bronchi. And again the each bronchus divide forming the bronchial tubes.

The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiniest bronchioles branch to the alveoli which are tiny, multi-lobed air sacs made of simple squamous cells.

5. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood.

6. In the meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide goes out of the lungs when we exhale.

7. The diaphragm's function is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity.

As the diaphragm contracts and relaxes, breathing takes place. When the diaphragm contracts, oxygen is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is removed out of the lungs.


Respiratory System Diseases:

1. Chronic Obstructive Pulmonary Disease (COPD) - lung disease causing shortness of breath.

2. Chronic Bronchitis - inflammation and permanent scarring of the bronchial tubes.

3. Asthma - constriction of hypersensitive airways.

4. Emphysema - damage to air sacs walls causing loss of elasticity.

5. Pleurisy - inflammation of the pleural membrane lining lungs and the chest cavity.

6. Lung Cancer - malignant tumors that develop in lung tissue.

7. Acute Bronchitis-inflammation of the bronchial tubes.

8. Influenza - serious infection cause by the influenza virus.

9. Pneumonia - infection of the lungs caused by a virus or bacteria.

10. Sinusitis - inflammation of the sinus cavities.

11. Common Cold - infection caused by a virus.

These are some common problems faced often.

How to take care of respiratory system to avoid problems?

Exercise to the Lungs helps the most. To exercise the Lungs one can do Yoga or meditation early in the morning to inhale fresh and pure air.

One can also try to observe the space between each breath. That is how many times you can breath in a set time. The ideal breathing should be deeper inhale and slower exhale but not to be forced.

These techniques are natural, easier and precautionary. And you can practice it daily as will not have any side effects. The exercise will also help your complete system not only the Respiratory System.
