The correct Answer is:
To answer the question "Tissue fixed macrophages are called:", we need to analyze the options provided and identify the correct term for tissue-fixed macrophages. ### Step-by-Step Solution: 1. **Understanding Macrophages**: - Macrophages are specialized immune cells that help in detecting and destroying harmful organisms like bacteria. They play a crucial role in the immune response and are found in various tissues throughout the body. 2. **Analyzing the Options**: - **Adipocyte**: These are fat cells that store energy as fat and are not related to macrophages. Therefore, this option is incorrect. - **Guano sites**: These are flagellated cells found in sponges and are not related to macrophages. This option is also incorrect. - **Plasma Cells**: These are derived from white blood cells and are involved in producing antibodies. They are not macrophages, making this option incorrect as well. - **Histocytes**: This term refers to stationary macrophages found in connective tissue. They have a role in scavenging and phagocytosis at their location. 3. **Identifying the Correct Answer**: - Since histocytes are the stationary form of macrophages that reside in tissues, the correct answer to the question is **Histocytes**. ### Final Answer: Tissue fixed macrophages are called **Histocytes**. ---

[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.
