1. What is Atrophy?
Answer:
Atrophy is the decrease in size of cells, tissues, or organs due to reduced workload, aging, lack of
nutrition, or decreased blood supply.
2. What is Chemotaxis?
Answer:
Chemotaxis is the movement of cells (especially white blood cells) toward the site of infection or
injury in response to chemical signals.
3. What is a Keloid Formation?
Answer:
A keloid is an excessive growth of scar tissue that extends beyond the original wound boundaries
due to overproduction of collagen.
4. What are the phases of wound healing?
Answer:
1. Hemostasis
2. Inflammatory phase
3. Proliferative phase
4. Remodeling (maturation) phase
5. What is a Pandemic?
Answer:
A pandemic is a widespread outbreak of a disease affecting large populations across countries or
continents.
, 6. What is Histamine? What does it do?

8. What does Latent Virus mean?
Answer:
A latent virus remains inactive within the host cells and can reactivate later under certain
conditions.
9. What are the stages of an infectious disease?
Answer:
1. Incubation
2. Prodromal
3. Acute (illness)
4. Convalescence
10. How does Lyme Disease Manifest?
