The brain does not contain fixed macrophages. Instead, microglia serve as the resident macrophages in the brain.
These are called macrophages and are part of the reticuloendothelial system, primarily found in tissues such as the liver, spleen, and lymph nodes.
Yes, macrophages contain lysosomes that contain digestive enzymes such as lysozyme and proteases. These enzymes help the macrophages break down and destroy invading bacteria and other pathogens.
Yes, the spleen contains numerous macrophages which are involved in removing old or damaged red blood cells, as well as in fighting infections by engulfing and destroying pathogens.
The organ that detects pathogens in the lymph is the lymph node. Lymph nodes contain immune cells, such as lymphocytes and macrophages, which monitor the lymph fluid for foreign substances, including pathogens. When pathogens are detected, the immune cells initiate an immune response to help eliminate the threat. This process is crucial for the body's immune surveillance and response to infections.
Fixed macrophages are a type of immune cell that reside in specific tissues and organs, as opposed to circulating in the bloodstream. They are derived from monocytes and play a crucial role in the innate immune response by phagocytosing pathogens, dead cells, and debris. Fixed macrophages are strategically located in various tissues, such as the liver (Kupffer cells), lungs (alveolar macrophages), and connective tissues, where they help maintain tissue homeostasis and initiate inflammatory responses when needed. Their ability to adapt to the local microenvironment allows them to perform specialized functions in immune surveillance and tissue repair.

Kuffper cells? These are the fixed macrophages ... Otherwise you may mean hepatocytes in the liver lobules. These contain many microvilli and carrier proteins facing the space of disse for nutrient exchange.
Yes, macrophages contain lysosomes that contain digestive enzymes such as lysozyme and proteases. These enzymes help the macrophages break down and destroy invading bacteria and other pathogens.
Liver
Lymph nodes are located along lymphatic pathways, and contain lymphocytes and macrophages, which destroy invading microorganisms. They remove and destroy potentially harmful foreign particles from the lymph through phagocytosis by macrophages. They are also the centers for the production of lymphocytes that act against foreign particles.Lymph nodes are located along lymphatic pathways, and contain lymphocytes and macrophages, which destroy invading microorganisms.
