Description: Mucosa is a membrane that lines various cavities in the human body and covers the surface of internal organs. This structure is fundamental for the functioning of the immune system and the protection of underlying tissues. The mucosa is composed of an epithelium that can vary in type depending on its location, and a layer of connective tissue called the lamina propria. Its main function is to act as a barrier, protecting the body from pathogens, chemical substances, and dehydration. Additionally, the mucosa is responsible for the secretion of mucus, a fluid that helps maintain moisture and facilitates the passage of substances through cavities. The mucosa is found in various parts of the body, including the respiratory tract, digestive system, reproductive system, and urinary system, highlighting its importance in multiple physiological functions. The health of the mucosa is crucial, as any alteration can lead to diseases or infections, underscoring its role in the homeostasis of the organism.
