immunsejt

Immunsejt, also known as an immune cell, is a type of cell that circulates throughout the body and is responsible for protecting the body from disease. These cells are part of the immune system, which is a complex network of cells, tissues, and organs that work together to defend the body against harmful invaders such as bacteria, viruses, and parasites.

There are many different types of immunsejt, each with its own specific role in the immune response. Some of the most important types include lymphocytes, phagocytes, and granulocytes. Lymphocytes, such as B cells and T cells, are responsible for recognizing and remembering specific pathogens, allowing the body to mount a more effective response upon re-exposure. Phagocytes, like macrophages and neutrophils, engulf and digest foreign particles and cellular debris. Granulocytes, including eosinophils and basophils, are involved in allergic reactions and defense against parasites.

Immunsejt constantly patrol the body, searching for signs of infection or damage. When they encounter a threat, they can activate other immune cells and initiate a coordinated response to eliminate the invader. This process involves a variety of mechanisms, including inflammation, antibody production, and direct cell killing. The precise functioning and interaction of these diverse immunsejt are crucial for maintaining health and preventing illness.
