Answer:
The matrix is a layer of living tissue that surrounds the nail and acts as a protective barrier against infection. It contains several types of immune cells, including macrophages, neutrophils, and T lymphocytes. These cells help to fight off bacteria and other pathogens that may enter the body through breaks in the skin or other openings.
The matrix also produces substances that help prevent infection from occurring. One such substance is lysozyme, which helps to destroy bacterial cell walls by breaking down proteins into smaller molecules. Another substance produced by the matrix is antimicrobial peptides.
