Explanation

COVID-19 primarily affects the lungs.

It leads to severe respiratory issues and pneumonia.

In critical cases, it can cause acute respiratory distress syndrome (ARDS), which can be lethal.

Explanation

During an asthma attack, the type of blood cell that increases in the blood is eosinophils

Eosinophils are a type of white blood cell:

These cells play a significant role in the body's response to allergic reactions, including asthma, by releasing substances that can help combat allergens. 

Explanation

 Bronchial Asthma is a reversible inflammatory condition of the airways

Inflammation:

The primary characteristic of asthma is chronic inflammation within the airways, involving the lining of the bronchial tubes. 

Reversibility:

This inflammation and resulting airway obstruction can be reversed with medication, allowing airflow to improve. 

Triggers:

Asthma symptoms can be triggered by various factors like allergens, exercise, cold air, or viral infections. 

Symptoms:

Common symptoms include wheezing, coughing, chest tightness, and shortness of breath.
