Which of the following are the sturctural and functional units of liver?

Options

A. Hepatic peritoneum
B. Hepatic lobules
C. Ligamentum teres
D. Falciform ligament

Answer

To determine the structural and functional units of the liver, we need to analyze the options provided:

1. **Hepatic Peritoneum**: This term refers to the peritoneum (the serous membrane lining the abdominal cavity) associated with the liver. It serves as a covering for the liver but is not involved in its functional activities. Therefore, this option is incorrect.

2. **Hepatic Lobules**: Hepatic lobules are the fundamental structural and functional units of the liver. They are small divisions of the liver tissue and consist of hepatocytes (the liver cells) arranged around a central vein, along with a portal triad (which includes a branch of the hepatic artery, a branch of the portal vein, and a bile duct). This option is correct as it directly relates to the liver's structure and function.

3. **Ligamentum Teres**: This is a ligament found in the liver, specifically a remnant of the umbilical vein. It does not serve as a functional unit of the liver but rather as a supportive structure. Thus, this option is also incorrect.

4. **Falciform Ligament**: This ligament is a fibrous structure that connects the liver to the anterior abdominal wall. While it is associated with the liver, it does not function as a structural or functional unit of the liver. Therefore, this option is incorrect as well.

Based on the analysis, the correct answer is **Hepatic Lobules**.

### Summary of the Solution:
- **Hepatic Peritoneum**: Incorrect (covering of the liver)
- **Hepatic Lobules**: Correct (structural and functional units of the liver)
- **Ligamentum Teres**: Incorrect (a ligament, not a functional unit)
- **Falciform Ligament**: Incorrect (connects liver to abdomen, not a functional unit)

### Correct Answer: Hepatic Lobules
