The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens, such as bacteria, viruses, and parasites. It plays a crucial role in protecting the body from infections and diseases by recognizing and attacking foreign invaders while also distinguishing them from the body's own cells. The immune system also helps to remove damaged or abnormal cells to maintain overall health and well-being.

The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful substances and invaders. It is responsible for protecting the body from infection, disease, and other threats. The immune system is made up of a variety of cells, including white blood cells, lymphocytes, macrophages, and natural killer cells. These cells are found in the blood, bone marrow, spleen, lymph nodes, and other tissues throughout the body.
The immune system works by recognizing and attacking foreign invaders, such as bacteria, viruses, and parasites. These invaders are called antigens. When the immune system detects an antigen, it produces antibodies that are designed to bind to and neutralize the antigen. Antibodies are also responsible for identifying and destroying infected cells.
In addition to antibodies, the immune system also uses other mechanisms to fight off infection. These include:
- Cell-mediated immunity: This type of immunity involves the activation of T cells, which are a type of white blood cell. T cells can kill infected cells and help to produce antibodies.
- Phagocytosis: This is the process by which macrophages, which are a type of white blood cell, engulf and destroy foreign invaders.
- Inflammation: This is a response to infection that involves the release of chemicals that cause swelling, redness, and heat. Inflammation helps to contain infection and promote healing.
The immune system is a critical part of human health. It helps to protect the body from a wide range of threats and keeps us healthy. However, the immune system can also be responsible for allergies, autoimmune diseases, and other disorders.
