The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Kupffer's Cells:** - Kupffer's cells are specialized cells located in the liver. They are a type of macrophage that plays a crucial role in the immune system. 2. **Location:** - These cells are found in the lumen of the liver sinusoids, which are small blood vessels within the liver. 3. **Function:** - Kupffer's cells are primarily known for their phagocytic activity. This means they can engulf and digest foreign particles, pathogens, and dead cells, contributing to the body's immune response. 4. **Shape:** - The shape of Kupffer's cells is star-like, which is why they are also referred to as "star cells." 5. **Alternate Names:** - Due to their function and shape, Kupffer's cells are also known as stellate macrophages. 6. **Conclusion:** - Given the characteristics of Kupffer's cells, they can be classified as: - Stellate cells (due to their star-like shape) - Star cells (another name based on their shape) - Phagocytic cells (due to their immune function) - Therefore, the correct answer is "all of the above." **Final Answer:** Kupffer's cells are stellate cells, star cells, and phagocytic cells. Thus, the correct option is D: all of the above. ---

[A] : Macrophage is a large amoeboid cell that can engulf, ingest and destroy bacteria, damaged cells and worn-out red blood cells. This process is called phagocytosis and is an important part of the body s defence against disease. [R]: Macrophages are found free (wandering) in the tissues, in connective tissue (as histiocytes), in the lining of the blood sinusoids of the liver (as Kupffer cells), and in lymphoid tissue. They make up the reticulo-endothelial system.
