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 and its folds in the stomach and small intestine, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Layers of the GI Tract**:
- The gastrointestinal (GI) tract consists of four main layers: Mucosa, Submucosa, Muscularis propria, and Serosa. The mucosa is the innermost layer.

2. **Identifying the Folds in the Stomach**:
- In the stomach, the mucosa layer forms irregular folds. These folds are known as **rugae**. Rugae help increase the surface area of the stomach and assist in the mechanical digestion of food.

3. **Identifying the Folds in the Small Intestine**:
- In the small intestine, the mucosa layer forms small, finger-like projections. These projections are called **villi**. Villi play a crucial role in the absorption of nutrients, as they increase the surface area available for absorption.

4. **Final Answer**:
- Therefore, the mucosa layer forms irregular folds called **rugae** in the stomach and small finger-like foldings called **villi** in the small intestine.

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