What is the Difference Between Mucus and Phlegm?

Mucus and phlegm are both substances produced by the body to protect and lubricate the respiratory system. However, they have some differences in their production locations and consistency:

• Mucus: This is a thinner secretion produced by the nose and sinuses. It provides a protective layer for the respiratory system, trapping dust, bacteria, and other particles before they can enter the lungs. Mucus is typically clear or white in color.
• Phlegm: This is thicker than mucus and is produced by the throat and lungs. Phlegm is a type of mucus that your body produces in the lungs and throat, which you then try to cough up. It is made mostly of water, inorganic salts, and proteins.

Both mucus and phlegm are made of water, antibodies, enzymes, proteins, and salt, and they carry dead cells, dust, and other debris from the nose and lungs. They work as part of the immune system, trapping particles breathed in through the airways, including viruses and bacteria. When you breathe through your nose, 80 percent of particles are filtered through the mucus lining.

Comparative Table: Mucus vs Phlegm

Mucus and phlegm are both substances produced by the body to protect and lubricate the respiratory system. However, they have different properties and purposes. Here is a table highlighting the differences between mucus and phlegm:

Both mucus and phlegm play crucial roles in supporting the immune system and maintaining respiratory health. However, their unique properties and purposes make them distinct substances in the body's defense mechanisms.
