Ciliated epithelium in human body is present in

Options

A. Kidney & stomach
B. Trachea & ureter
C. Cavity of brain and fallopian tube
D. Stomach & urinary bladder

Answer

### Step-by-Step Solution:

1. **Understanding Ciliated Epithelium**:
- Ciliated epithelium is a type of epithelial tissue that has hair-like structures called cilia on its surface. These cilia are capable of rhythmic movement.

2. **Function of Ciliated Epithelium**:
- The primary function of ciliated epithelium is to move particles or fluids in a specific direction. This movement helps in the removal of waste and the transportation of important substances within the body.

3. **Locations of Ciliated Epithelium**:
- Ciliated epithelium is found in specific areas of the human body. Notably, it is present in:
- The trachea (windpipe), where it helps in moving mucus and trapped particles out of the respiratory tract.
- The fallopian tubes (in females), where it assists in moving the ovum from the ovary towards the uterus.
- The ureters, which transport urine from the kidneys to the bladder.

4. **Exclusions**:
- Ciliated epithelium is **not** found in the kidneys, stomach, urinary bladder, or the brain cavity. These areas do not require the same type of movement that ciliated epithelium provides.

5. **Conclusion**:
- Based on the above information, the correct answer to the question "Ciliated epithelium in human body is present in" is the **trachea and ureter**.

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