Which of the following is the structural and functional unit of liver in humans ?

Options

A. Hepatocyte
B. Hepatic cord
C. Hepatic lobule without Gillsson's capsule
D. Hepatic lobule with Gillsson's capsule

Answer

To determine the structural and functional unit of the liver in humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Liver's Role**: The liver is the largest gland in the human body, weighing approximately 1.2 to 1.5 kg. It is essential for various functions, including the secretion of bile.

2. **Identify Liver Cells**: The primary cells of the liver are called hepatocytes. These cells are crucial for the liver's functions but do not represent the structural and functional unit of the liver.

3. **Explore Hepatic Cords**: Hepatic cords consist of masses of hepatocytes arranged in irregular rows and columns. While they are important, they are not considered the structural and functional unit of the liver.

4. **Define Hepatic Lobules**: Hepatic lobules are the minute, branched structures that make up the liver. They are surrounded by a layer of dense connective tissue known as the Glisson's capsule.

5. **Understand the Importance of Glisson's Capsule**: The Glisson's capsule surrounds the liver and supports the division of the liver into smaller polyhedral units known as hepatic lobules. This structure is vital for the liver's organization and function.

6. **Determine the Correct Option**: Among the options provided, we need to identify the one that describes the structural and functional unit of the liver. The correct answer is "Hepatic Lobules with Glisson's Capsule," as they are the functional units that allow for the liver's various functions.

### Final Answer:
The structural and functional unit of the liver in humans is **Hepatic Lobules with Glisson's Capsule**.
