Macrophages

Macrophages are a type of immune cell in the body that play a crucial role in defending against infections and maintaining overall health. They are often referred to as "big eaters" because they engulf and digest harmful bacteria, dead cells, and debris. Macrophages also help coordinate the immune response by releasing signals that attract other immune cells. They are found throughout the body, including in tissues and organs, and can adapt their functions based on the needs of the body, making them essential for both fighting off illness and promoting healing.
