Interactive Biology TV: Cellular Adaptations

Host Introduction

• Host: Leslie Samuel
• Episode focus: Types of Cellular Adaptations
• Previous topics:
  • What is a disease?
  • Five causes of disease (including cellular adaptation)

Cellular Adaptation Overview

• Definition: Cellular adaptation is a reaction to prevent injury from an injurious agent in the cell's environment.
• Importance: It is the first cause of disease.

Four Types of Cellular Adaptations

1. Atrophy

• Description: Decrease in the cell's functional parts.
• Effect: Cell reduces in size.

2. Hypertrophy

• Description: Increase in the size of individual cells.
• Effect: Tissue increases in size.

3. Hyperplasia

• Description: Increase in the number of cells.
• Effect: Tissue increases in size due to more cells.

4. Metaplasia

• Description: Replacement of one tissue type by another.

Conclusion and Next Steps

• Memorize the four types of adaptations: Atrophy, Hypertrophy, Hyperplasia, Metaplasia.
• Next video will cover Atrophy in detail.
• Additional resources available at interactivebiology.com.

Note

• Emphasized repetition of the names of the adaptations for memory aid
• Encouraged engagement with the content by reciting along with the host.
