Top 5 RESPIRATORY DISORDERS 2022
Top five RESPIRATORY DISORDERS are describe below.
Many problems in the respiratory system can take place if the inside lining is continuously exposed to unhealthy air containing smoke and other pollutants.
Lung cancer is one of the most serious diseases of the respiratory system.
Cancer or carcinoma is a malignant tumor of potentially unlimited growth.
locally by invasion and
systemically by metastasis
EFFECTS OF CANCER
Cancer can block respiratory passages because the tumor replaces lung tissue.
It is now estimated that 90 % of lung cancer is caused by smoking.
Smoking especially in young adults is the most possible threat to lung cancer.
The chances of lung cancer are 10 times more in those persons, who smoke or live in smoky and congested areas as compared to those who do not smoke.
Recent research indicates, that more than 10 compounds of tar in tobacco smoke are involved to cinscausingcer
Tuberculosis is a disorder of the respiratory system.
It is a contagious disease.
Tuberculosis is the general name of a group of diseases caused by Mycobacterium tuberculosis.
It is more common in poor people.
Malnutrition and poor living conditions facilitate Mycobacterium to grow.
Pulmonary tuberculosis is a disease of the lungs in which the inside of the lung is damaged resulting in cough and fever.
The disease is curable with proper medical attention.
Asthma is a serious respiratory disease.
• It is associated with a severe paroxysm of difficulty breathing followed by a period of complete relief then again attack at frequent intervals.
● It is an allergic reaction to pollen, spores, cold, humidity, and poll. etc.
This allergic reaction causes sudden/spasmodic contraction of small bronchioles.
Asthma results in the release of inflammatory ( ) chemicals such as histamines into the circulatory that cause severe contraction of the bronchiole.
Emphysema is a breakdown of alveoli.
This respiratory problem is more common among smokers.
The substances present in the smoke of tobacco weaken the wall of the alveoli.
The irritant substances of smoke generally cause ” smoker’s cough ” and coughing bursts some of the weekend alveoli.
As a result of constant coughing, the absorbing surface of the sun is greatly reduced.
The person suffering from emphysema cannot oxygenate his blood properly the least exertion makes him breathless and exhausted.
Emphysema blocks the bronchioles as a result of inflammation and air is trapped in the alveolar sacs.
Therefore, the air in the alveolar sacs is not ventilated.
5: RESPIRATORY DISORDERS SYNDROME
It is common in premature infants, especially in infants with a gestation age of fewer than 7 months.
This occurs because enough surfactant is not produced to reduce the tendency of the lungs to collapse.
Surfactant is a mixture of lipoprotein molecules produced by the secretory cells of the alveolar epithelium. This mixture forms a layer over the surface of the fluid within the alveoli to reduce the surface tension.
