<p>Mucosal associated lymphoid tissue (MALT) covers lymphoid tissues associated with the mucosal surfaces of [[Alimentary - Anatomy & Physiology|alimentary]], [[Cardiorespiratory System - Anatomy & Physiology|respiratory]], [[Urinary System - Anatomy & Physiology|urinary]] and [[Reproductive System - Anatomy & Physiology|reproductive]] tracts. Due to the extent of these surfaces the mucosal lymphoid tissue contains as many [[Lymphocytes - Introduction|lymphocytes]] as the rest of body. The MALT is strategically located to intercept pathogens before they enter the body.</p>
