Which Cells of Liver plays role in absorption of Vit.A and Vit.D?
**Core Concept**
The liver plays a crucial role in the metabolism and storage of various vitamins, including **Vitamin A** and **Vitamin D**. Hepatocytes are the main cell type of the liver, responsible for a wide range of functions including detoxification, protein synthesis, and production of biochemicals necessary for digestion.
**Why the Correct Answer is Right**
Hepatocytes are responsible for the uptake, storage, and metabolism of **Vitamin A** and **Vitamin D**. They contain specific receptors and enzymes that facilitate the absorption and conversion of these vitamins into their active forms.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while Kupffer cells are involved in the immune response and phagocytosis, they are not primarily responsible for vitamin absorption.
**Option B:** This option is also incorrect as stellate cells are involved in the storage of vitamin A but not in the absorption of vitamins.
**Option C:** This option is incorrect because bile duct cells are primarily involved in bile production and secretion, not vitamin absorption.
**Option D:** This option is not provided, however, hepatocytes are the correct answer.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that **Vitamin A** and **Vitamin D** play critical roles in maintaining healthy vision, immune function, and bone health.
**Correct Answer:** D. Hepatocytes.
