human blood monocytes
Osteoclasts. They are phagocytic just like macrophages and originate from the same stem cells in the bone marrow as macrophages.
Macrophages originate from monocytes, which are a type of white blood cell produced in the bone marrow. Once they enter the bloodstream, monocytes can migrate to various tissues and organs where they differentiate into macrophages.
macrophages.
Macrophages are a type of white blood cell derived from monocytes. They play a key role in the immune response by engulfing and digesting pathogens, dead cells, and debris. Macrophages are important for initiating inflammation and promoting tissue repair.
Steroid hormones are derived from cholesterol, which is a type of fat molecule. Cholesterol is modified and converted into different steroid hormones by various enzymes and processes in the body. These hormones play crucial roles in regulating various physiological processes in the body.
Alveolar macro-phages uptake debris which reach the alvoli. they are derived from circulating monocytes as well as mitotic division of already present macrophages.
Nearly all hydrocarbons are derived from petroleum.
Macrophages do not replicate. The bone marrow produces Monocytes which when they find a damaged area transform into Macrophages.
Macrophages play a key role in the immune system by engulfing and digesting pathogens, dead cells, and cellular debris. They also present antigens to activate other immune cells, produce inflammatory mediators, and contribute to tissue repair and remodeling. Overall, macrophages serve to promote immune responses, maintain tissue homeostasis, and participate in various physiological processes.
The brain does not contain fixed macrophages. Instead, microglia serve as the resident macrophages in the brain.
