What Is Mucus Secretions?

Every now and then, you feel a slimy and slippery liquid that goes out of your mouth or nose. That slippery liquid is called mucus secreted by the different vital systems in the body such the respiratory, reproductive, and digestive system. Secretion of mucus is normal, and it plays several functions to protect the body against foreign objects and diseases.

Mucus is a protein-based fluid that contains a mixture of water, mucin, inorganic salts, and important cells that secrete mucus such as leukocytes and epithelial cells.

Types of Mucus Secreted by the Body

There are three different systems in the body that produces thick mucus secretions.

These three include the following:

• The Respiratory System. The mucus secreted by the respiratory system are found in the linings of nasal cavities and prevents successful entry of foreign particles such as dust, airborne pollutants, and bacteria. The mucus traps unwanted particles and slides them down deeper to the respiratory system. They are received by leukocytes or immune system cells that secrete mucus and bring them back up and out of the respiratory system. Constant exposure to cigarette smoke and other pollutants weakens the immune enhancing function of mucus resulting to sickness and respiratory illnesses.

• The Female Reproductive System. Just like the mucus secreted in the respiratory system, the mucus secreted by the female reproductive system functions as a protection against successful entry of microorganisms to the body thru the vagina. It also helps successful sperm migration to the uterus and keeps unhealthy sperm from entering the uterus.
• The Digestive System. Mucus secretions can be found all throughout the digestive tract to promote successful digestive process. The mouth secretes mucus to aid the body in swallowing food and smooth passage in the esophagus. Once the food reaches the stomach, the mucus produced by the stomach enhances grinding and good digestion as the food passes the intestines and out of the body.
