The lungs are a major human respiratory organ.  The two lungs, the two bronchi, a trachea, a larynx, a glotis, and the nostrils and nostrils way play important roles as the main respiratory organs of man.  The human lungs are located on either side of the heart and above the diaphragm.  The two lungs are triangular in shape and snail-shaped, and lungs are slightly darker in color.  The human lungs tend to hang on the chest like two sponges and two sacs. 

The lungs are covered with a covering,is called plura.  This plura layer again consists of the visceral layer and the parietal layer.  The two lungs are connected by the pulmonary artery with the right ventricle of the heart and by the pulmonary vein with the left atrium.  The human right lung is slightly larger than the left lung and has 3 segments whereas the left lung has two segments.  Each lung contains a number of tiny air sacs or alveoli.  In order to be surrounded by these alveoli, there is an exchange of air.

VITAL ROLE OF LUNGS:

When oxygenated air enters the air sacs of the lungs, oxygen enters in the air sacs in the process of diffusion and then this oxygenated blood enters the heart from the lungs through the pulmonary veins.  The blood from the heart spreads through the arteries to all the blood vessels in the body and the process of oxygen diffusion enters the lymph and reaches the various cells of the body from the lymph.  In this way, oxygen reaches every cell in the human body through the work of the lungs.  On the other hand, the carbon dioxide produced by the cells as a result of respiration reaches the bloodstream through the Lumph and the diffusion process enters the bloodstream.  This carbon dioxide from the bloodstream then travels through the bloodstream to the heart and from the heart to the lungs through the pulmonary arteries.  Carbon dioxide then enters the air sac through the lattice of the lung air sac.  The lungs thus play a vital role in getting oxygen to every cell in the human body and in carrying out the polluted carbon-di-oxide from different cells.

Lungs disease:

At present, due to various environmental factors, various pollutants in the air and various environmental toxins, the lungs are getting diseased in various ways and human society is heading towards severe damage. 

Asthma:

Various allergens, air pollutants and various chemicals in the environment cause asthma in humans.  Chemicals in Cigarette Smoke, Various volatile chemicals such as polyvinyl chloride and paracetamol also cause asthma in humans.  The tiny germs mixed in the dust of the air, Arsola plays a role in the creation of such  asthma.  In many ways these contaminants enter the airways and cause rapid and uncontrolled contraction of the bronchial muscles.  Asthma causes difficulty breathing, frequent coughing, pain in the chest, and coughing. 

Bronchitis:

Bronchitis can be caused by the inhalation of various pollutants such as dust, sand, etc. into the air.  Bronchitis is caused by the growth of mucous glands and goblet cells on the bronchi of the respiratory tract.  This disease results in yellow and green mucus in the phlegm, shortness of breath, slight fever, discomfort in the chest, wheezing during breathing. 

 Lung Cancer:

Particulars that cause cancer are called carcinogens.  Various radioactive substances, pesticides, herbicides and various chemicals have carcinogenic properties.  Various smokers have a higher risk of cancer because cigarette smoke contains at least 70 carcinogens.  Vinyl chloride, Pluric acid are the examples of carcinogen.  Radium made from uranium fractures, as well as asbestos, sulfate-containing aerosols, fine particles floating in the air, can cause lung cancer.  Problems caused by lung cancer cause chronic coughing, hemorrhagic cough and hemorrhagic coughing.  There is also difficulty in eating, recurrent bronchitis, sore throat, hoarseness and pneumonia.

         Covid-19:

It is a type of droplet infection disease.  The disease is not contagious if it is in contact with an infected person, but can only be transmitted through sneezing, speech, or a small droplet of saliva reaching the lungs through another person's trachea.  Since March 2000, almost every country in the world has been affected by the Corona and many people have died from the epidemic.  Currently in 2021, the impact of this Covid-19 is going on lockdown in many countries of the world. 

Special observations have shown that touching an infected person does not cause the disease, but the first onset of the disease occurs directly in the lungs when the fine particles or droplets coming out of the infected person's mouth or nose reach another person's lungs through the airways.  A person with covidosis develops shortness of breath due to lung infection and various symptoms such as redness of the eyes after headache are seen.  This disease requires oxygen to reduce shortness of breath and the patient is subsequently treated by reducing shortness of breath through oxygen.  This lung infection is now the epidemic in the world, so there is a special need to protect the lungs in many ways.  In this extreme situation, just as it is very important to maintain the quality of the essential elements in the air, water and soil of the environment, people must consciously follow the rules of lockdown and use Face Musk to protect themselves from infection.

In this corona situation, on the one hand, it is necessary to increase the body's immunity through nutritious food, and on the other hand, it is necessary to keep oneself away from smoking.  It should be kept in mind that since Covid  a droplet infectious disease, even if it is ingested with food, no one will be infected, so if a person infected with Covid is not in danger, we should stand by his side.  In this case, care must be taken so that no infection of the infected patient enters us through the nose or mouth.  In this difficult situation, everyone should be aware that Covid does not kill people and its mortality rate is less than 2% but Covid patient breaks down emotionally while in isolation and his immunity gradually decreases so the patient suffers from this fear of losing confidence.  So well-known  that Covid patients need to make arrangements to spend time through easy-to-digest nutritious food and various stimulant activities.  If breathing difficulties are high, oxygen cylinders should be arranged as per the doctor's advice. If not, special attention should be paid to stay fresh at home or hospital through regular exercise and nutritious food while in isolation.  It is mandatory to use the advanced N95 face musk before going out while in isolation, but it is also advisable not to use the musk as advised by the doctor while at home. 

By maintaining social distance and taking careful precautions in this difficult situation, it is hoped that very soon we will be able to protect ourselves from this epidemic.  Cigarettes, bidis and other intoxicants should not be consumed during this time. It is very important to take nutritious food and exercise regularly to maintain physical fitness.  There is a special need at this time for each and every one of us to take responsible care of the human society because human beings are for the society and we are for each and every one of us.
