Mucosa layer form irregular folds called____in stomach and small finger like foding called____ in the small intestine.

Answer

To answer the question regarding the mucosa layer in the stomach and small intestine, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding the Mucosa Layer**: The mucosa layer is the innermost layer of the gastrointestinal tract, which plays a crucial role in digestion and absorption.

2. **Identifying the Stomach's Mucosal Folds**: In the stomach, the mucosa layer forms irregular folds. These folds are known as **rugae**. Rugae allow the stomach to expand when food enters and help in the mechanical digestion of food.

3. **Identifying the Small Intestine's Mucosal Folds**: In the small intestine, the mucosa layer has small, finger-like projections that increase the surface area for absorption. These projections are called **villi**. Villi are essential for nutrient absorption as they provide a larger surface area for the nutrients to be absorbed into the bloodstream.

4. **Finalizing the Answers**: Therefore, the answers to the blanks in the question are:
- The irregular folds in the stomach are called **rugae**.
- The small finger-like projections in the small intestine are called **villi**.

### Complete Answer:
The mucosa layer forms irregular folds called **rugae** in the stomach and small finger-like folding called **villi** in the small intestine.
