Flashcards

Asthma's Inflammatory Cells

Immune cells that are involved in the inflammatory response in asthma. They include eosinophils, mast cells, macrophages, lymphocytes, neutrophils, and epithelial cells.

Hygiene Hypothesis

A theory that suggests that reduced exposure to infections in modern societies might contribute to a rise in allergic diseases like asthma.

Asthma's Core Feature

The defining characteristic of asthma is the intermittent and reversible narrowing of the airways in the lungs. This narrowing can occur due to muscle spasms, inflammation, and mucus buildup.

When Asthma Hits Hardest

Asthma symptoms often get worse at night and early morning, probably due to hormonal changes and increased airway sensitivity during these hours.

Eosinophils' Role in Asthma

Eosinophils, a type of white blood cell, play a significant role in the inflammatory process of asthma. They are found in increased numbers in the airways of people with asthma.
