Respiratory system is a system which helps breath in oxygen and give out carbondioxide. There are a number of organs functioning to help you breathe properly. Following are the functions of the respiratory system:
- BREATHING: When you breathe in air through the nostrils, it enters the nose and passes through trachea/windpipe and into a number of tubes known as bronchial tubes. These enter into lungs through bronchioles. Over 300 million alveoli are then filled with air. Numerous blood vessels surround these alveoli function to suck oxygen from air and carry it to the heart. This oxygen is pumped in to the whole body to supply it to various cells. Carbondioxide is released in this process which is carried through these vessels back to the heart and lungs, and exhaled out of the body as the process continues. The cycle keeps on repeating. Diaphragm is the most important organ which is a dome shaped muscle, resting beneath the lungs. With each breath, the diaphragm moves downward, creating negative pressure, sucking in air. Upon exhaling, the diagram moves upward and outward forcing out the carbondioxide. Injury to the diaphragm can create serous problems in breathing.
- CLEANING AIR: The respiratory system also serves as a defense mechanism. The tiny hair in the nostrils move back and forth and filters dust particles by moving them away. The mucus produced in the respiratory system also serves to protect from the invading organisms and entering into the body. Lungs also serve to protect from the invading particles, which manage to cross the previous barriers, by coughing them out.
MAJOR RESPIRATORY SYSTEM DISEASES:
Foreign objects/organisms are not always blocked by the respiratory system. Cigarette smoke, allergens, chemicals, genetics, and environmental factors might create serious respiratory problems. Following are the most common respiratory diseases:
- ASTHMA: In this condition there is inflammation of the bronchi and bronchioles, leading to narrowing of the airways and difficulty in breathing. Triggering substances are, cold air, pollen, fumes, allergies, cleaning products, medications, cigarette smoke and more.
- CHRONIC OBSTRUCTIVE PULMONARY DISEASE: The condition involves chronic asthma, chronic bronchitis, and emphysema. This also makes it difficult for the person to breath due to environmental factors or genetics. The condition progresses creating problems in breathing while lying down.
- LUNG CANCER: It is most commonly due to cigarette smoking and tobacco but can be in people who are never exposed to smoke. There is abnormal cell growth creating limitations in breathing
- Pneumonia, which is infection of lungs
- Bronchitis is infection of bronchial tubes.
- Recurrent infection leads to widening of airways and damage leading to bronchietasis.
- Tuberculosis and inflammation of tonsils are also common.
COMPONENETS OF THE RESPIRATORY SYSTEM:
Respiratory system is made of a number of organs, all depend on one another. If one of them goes wrong, the entire system might shut down.
UPPER RESPIRATORY SYSTEM:
- Nasal cavity
LOWER RESPIRATORY SYSTEM:
- Air sacs/alveoli
