Ciliated epithelium is present In

Options

A. Trachea
B. Ureter
C. Intestine
D. Nasal chamber

Answer

### Step-by-Step Solution:

1. **Understanding Ciliated Epithelium**: Ciliated epithelium consists of a single layer of tightly packed columnar or cuboidal cells that have cilia on their surface. These cilia are hair-like structures that help in movement and transport of substances.

2. **Identifying Locations**: Ciliated epithelium is primarily found in areas where movement of substances is necessary. It is commonly located in the respiratory tract, specifically in the trachea, bronchi, and bronchioles.

3. **Other Locations**: Besides the respiratory tract, ciliated epithelium can also be found in the female reproductive system (such as the uterus and oviducts) and in the central nervous system (like the ventricles of the brain and spinal canal).

4. **Analyzing the Options**: The question provides four options: trachea, ureter, intestine, and nasal chamber. We need to identify which of these options is most commonly associated with ciliated epithelium.

5. **Selecting the Correct Answer**: Among the options, the trachea is the most appropriate answer as it is a part of the respiratory tract where ciliated epithelium is typically found. The ureter and intestine do not primarily feature ciliated epithelium, and while the nasal chamber does have some ciliated cells, it is not as definitive as the trachea.

### Final Answer:
Ciliated epithelium is present in the **trachea**.
