The immune system is a complex system designed to protect the body from harm. It is composed of various organs, cells, and proteins all working together.
White blood cells are the workhorse of the immune system. They patrol the body and are responsible for detecting and destroying foreign invaders.
Vaccines achieve their effects by introducing antigens, which stimulate the white blood cells to create a memory of the antigen and prevent it from entering the body in the future.
B-cells play an essential role in long-term immunity by producing antibodies that recognize and bind to antigens. B-cells allow them to destroy the antigens.
Natural Killer cells are a type of lymphocyte that can detect and destroy virus-infected and tumor cells.
The thymus is a vital organ in the chest cavity that helps mature T-cells.
Inflammation is a process that protects the body from harm by releasing molecules such as histamines to alert other components of the immune system to an injury.
Complement proteins are a group of proteins involved in immune response which help to facilitate the destruction of foreign bodies.
The immune system responds to foreign body antigen molecules.
Macrophages are a type of immune cell that can engulf and digest bacteria, viruses, and other foreign bodies.
The skin is an integral part of the immune system, acting as a physical barrier to prevent foreign bodies from entering the body.
