How oxygen supplied through lungs to body vs. Complication after covid-19?

Healthy lungs is important not only for breathing but for overall healthy body. Lung is that organ which turns blood to be oxygenated and that reaches to every part of the body.







  • If you see the Lungs of a healthy person and a person who smokes you can easily differentiate. Damage lungs actually reduces life span of person who smokes and this damage increases day by day with smoking.

  • Have you ever seen a person who is struggling for a breath and person who is depended on oxygen mask, these person are mostly those person who have smoking history.

  • Today's environment have so many  viruses and infections which can easily  target person whose Lungs is already damaged or have some kind of lungs disease. 

  • So it's important to maintain this organ healthy but before this you need to how healthy lungs works.






How healthy lungs works.


Everyone has two lungs which  lies in thoracic cavity (upper portion from stomach)and both lungs have lobes , right one is divided in three lobes and left  one is divided into two lobes.
Lungs  also have outer layer on it which it called pleura.That is made up of two layers called visceral pluera and parietal plurea. 

The visceral layer is adherent to the Lungs & it is inner layer. The parietal puera is adherent to the wall of thoracic cage.

These layer have serious fluids within it that prevent friction within it when we breaths.







Air passages from the communication between the atmospheric air and the Lungs tissue. It includes following parts:
Nose

Nasal cavity

Pharynx

Larynx

Trachea (wind pipe)

Bronchi 




Bronchi

  • It is a structure within the Lungs that spread like a branch of a tree and works as a passage way for moving the air into the Lungs.

  • Now  Bronchus  ( tree shaped structure)  is divided in further sections which is called bronchioles, respiratory bronchiole, alveolar ducts and alveoli.(when we inhales from nose the air travelled from nose to alveoli).



Alveoli with capillaries network


  • Alveoli are the last section of the Bronchus which looks like small pockets.

  • Alveoli are the functional unit of the Lungs because it helps in the exchange of gas (Oxygen & carbondioxide).

  • Each alveoli is surrounded by capillary networks,(smallest branch of arteries that carry blood) exchange of gases between air in the alveoli  and blood in the capillary takes place at this point.

  • Alveoli helps to enter oxygen in blood and takes carbon dioxide from blood and remove it when we exhale.

  • Thats how gaseous exchange take place in healthy lungs.

  • But if Alveoli becomes damaged then the exchange of gas is not properly happen and complication related to breathing starts.







SOME CONDITIONS IN WHICH LUNGS DAMAGE


Empyema

It is a condition in which pus  is accumulated in pleural cavity.



Emphysema

In this condition the alveoli in the Lungs gets damaged and gets dilated for permanently that impaired gas exchange




Atelectasis

It is a condition in which failure to expand the part of lungs due to collapse or closure of alveoli. 





Bronchiectasis

It is a condition in which permanent or irreversible dilation of large airway (bronchial tree) occurs due to destruction of muscles and elastic tissue.





Pneumonia

It is an inflammation of lungs parenchyma which is associated with marked increase in interstitial and alveolar fluids.

The cause for these conditions are :



  • Viral infection 

  • Bacterial infection

  • Alcoholism 
  • Allergens 

  • Cigarette smoking 

  • Environmental pollution

  • Environmental conditions  (cold)





But further damage to lungs can be prevented by taking precaution at early like,

  • Immunized yourself properly.

  • Take extra care of yourself  during winter.

  • Avoid smoking.

  • Avoid alchohlism.

  • Wear mask to avoid environmental pollution.

  • Make sure not comes in contact with allergens.

  • And most importantly take medical advice from Doctor before it gets worse.

So, the Lungs are the most important part of the body without healthy lungs it is difficult to other organs to function properly as  lungs supplies oxygen to other organs of body to perform there function properly.
