Summary Introduction
To determine:
The role of the skin and mucosal membranes in the body’s defenses.
Concept introduction:
The skin maintains the pH in acidic condition to prevent the entry of microbes and mucosal membrane secrets some mucous secretion, which prevents the growth of pathogenic microorganisms. Both skin and mucosal membranes act as physical barriers for the foreign microorganism.
