COVID 19

The corona virus at 1/100 the size of a human cell, threatens the people on the earth which is 8000 X 1,609,344,000,000 its size.

INHALATION
The virus enters the lungs and travels to the smallest parts of the lungs, tiny lung sacs called the alveoli where oxygen exchange takes place
CELLULAR INVASION
Corona virus invades the cells of the alveoli by using its spike glycoproteins. These spike proteins attach to the cell membrane and the virus can then enter the cell.

INFLAMMATION
The virus replicates and invades more cells of the alveoli
As COVID-19 causes inflammation of the the lungs, infected fluid fills the lungs thus disrupting gas exchange.

PROGRESSION AS THE DISEASE SPREADS IN THE LUNGS
The infection starts in small basal segments

PROGRESSION
and progresses to involve more and more lung
Ashley Davidoff
INITIAL PATCHY INVOLVEMENT
It spreads to both lungs
MULTIFOCAL PNEUMONIA
Advancing infection involves more lung and prevents efficient and effective gas exchange (inhalation of oxygen and expiration of carbon dioxide). When this exchange is not possible, a ventilator is necessary
