Bronchus-associated lymphoid tissue (BALT)

Bronchus-associated lymphoid tissue (BALT) is a collection of immune tissues located in the airways of the lungs. It plays a crucial role in the body’s defense system by monitoring for harmful pathogens, such as bacteria and viruses, that we inhale. BALT contains immune cells that help recognize and respond to these threats, promoting respiratory health. This system is part of the larger mucosal immune system, which protects various entry points in the body. Understanding BALT is important for studying respiratory conditions and the immune response in the lungs.
