Questions and Answers
What happens when the epithelial mucosal cells are damaged?
What happens when the epithelial mucosal cells are damaged?
- They are shed quickly and replaced by undifferentiated stem cells (correct)
- They multiply to form a tumor
- They differentiate into new cells
- They secrete digestive enzymes
What is the consequence of persistent inflammation in the stomach?
What is the consequence of persistent inflammation in the stomach?
- Atrophy of the gastric glands
- Hypersecretion of digestive enzymes
- Formation of gastric ulcers (correct)
- Increased production of mucus

Study Notes
Histology of the Large Intestine
- The large intestine comprises four layers: mucosa, submucosa, muscular layer, and serosa.
- Circular folds are present in both the mucosa and submucosa, enhancing surface area.
- Intestinal villi are finger-like projections from the mucosa, housing lacteals (lymphatic capillaries) for fat absorption.
- Epithelial mucosal cells are rapidly shed and replaced, ensuring quick recovery from damage.
- Breaches in the mucosal barrier lead to inflammation, potentially resulting in peptic ulcers if chronic.
Regions of the Small Intestine
- The text highlights the significance of gastric glands and various cell types within the stomach.
- Understanding the structure and function of the small intestine is crucial for grasping the entire gastrointestinal tract (GIT).
