Transcribed Image Text:### Intestinal Lining: Structure and Function
---
**Functions:**
- **Protection:** The intestinal lining acts as a barrier against harmful substances and pathogens.
- **Secretion:** It aids in the secretion of necessary digestive enzymes and hormones.
- **Absorption:** The primary role is to absorb nutrients from digested food into the bloodstream.
**Illustration Explanation:**
- **Diagram:** The image consists of a labeled diagram showing a section of the intestinal lining.
- **Microvilli:** These are tiny, finger-like projections that increase the surface area for absorption.
- **Cytoplasm:** The gel-like substance within cells, providing a medium for cellular processes.
- **Nucleus:** The central part of a cell that contains genetic material.
- **Basement Membrane:** A thin layer that supports and anchors the epithelial tissue.
- **Loose Connective Tissue:** Found underneath the basement membrane, providing structural support and flexibility.
- **Light Micrograph (LM):** A magnified image (x350) of the intestinal tissue highlighting cellular structures.
This schematic provides an overview of the intestinal lining's role and microscopic anatomy, essential for understanding its function in maintaining digestive health.
