Final Answer:
Macrophage found in liver are called Kupffer cells found in brain called Microglia. Thus, the correct answer is option A. Kupffer cells; Microglia.
Step-by-step explanation:
Macrophages found in the liver are called Kupffer cells, while those found in the brain are called Microglia. Kupffer cells are specialized macrophages located in the liver sinusoids, where they play a crucial role in filtering and clearing foreign particles, including bacteria and worn-out blood cells. On the other hand, Microglia are the resident immune cells of the central nervous system, including the brain. They are responsible for immune surveillance, responding to pathogens, and maintaining the overall health of the brain tissue.
Kupffer cells in the liver are vital for the organ's immune defense and overall function. They help in detoxification, removal of debris, and modulation of inflammatory responses. In the brain, Microglia have essential functions in maintaining homeostasis, supporting neuronal function, and responding to injury or infection. Both Kupffer cells and Microglia are examples of tissue-resident macrophages, adapted to the specific needs and microenvironment of their respective organs.
Thus, the correct answer is option A. Kupffer cells; Microglia.
