COVID-19 and Respiratory System

When the coronavirus receives in to the frame, it comes into touch with the mucous membranes that line nose, mouth, and eyes. The virus enters a healthful cell and uses the cell to make new virus parts. It multiplies, and the brand new viruses infect nearby cells. Think respiratory tract as an upside-down tree. The trunk is a trachea, or windpipe. It splits into smaller and smaller branches in the lungs. At the end of every department are tiny air sacs known as alveoli. This is where oxygen goes into the blood and carbon dioxide comes out.

The new coronavirus can infect the upper or lower a part of the breathing tract. It travels down in airways. The lining can become irritated and inflamed. In some cases, the contamination can reach the entire manner down into alveoli. COVID-19 is a brand new condition, and scientists are learning greater each day about what it can do on lungs. They agree with that the effects on the frame are similar to the ones of two other coronavirus diseases, excessive acute respiratory syndrome (SARS) and Middle East breathing syndrome (MERS).        

• Cell invasion and viral replication in the nose
• Replication in the lung and immune system alerted
• Pneumonia
• Acute respiratory distress syndrome, the cytokine storm, and multiple organ failure
