T Lymphocytes

T lymphocytes, or T cells, are a type of white blood cell essential for the immune system. They develop in the thymus gland and help protect the body from infections and abnormal cells, like cancer. T cells recognize specific pathogens or infected cells through unique receptors and can directly destroy these threats or coordinate other immune responses. There are different types of T cells, including helper T cells that activate other immune cells, and cytotoxic T cells that kill infected cells. Overall, T cells are crucial for identifying and eliminating harmful invaders, maintaining the body's health.
