It protects your immune system and Mucus collects bacteria and prevents it from entering your blood stream. It is carried away by your lymphatic system. It is one of the many first line immune defenses that body uses to fight disease. Drugs that limit mucus formation keep this defense mechanism from working and put more burden on the other natural defenses.

Mucus entraps microorganisms, and so helps protect the reproductive, digestive, respiratory and urinary systems. An enzyme in mucus called lysozyme kills bacteria - you find lysozyme in tears and saliva too. In the stomach the hydrochloric acid in gastric juice also kills bacteria.

Is it normal to sneeze and mucus have blood in it?

small amounts...ruptured (abrasions on the) mucus membranes from irritation. shouldn't be a big deal. Large amounts, could be a ruptured blood vessel from strain and irritation..also not that big a deal, but it could also be a sign of an infection, depends on what color your mucus is. if it's brown, like poop brown, you may need to go to the doc for antibiotics, this generally means a bacterial or fungul infection. Green means infection too, but over the counter meds should suffice. Yellow or white then it's ok, just your body upping the normal mucus amounts in your sinuc cavieties to protect from further infection while your body fights the cold already in your system. Mucus acts just like natural vasoline to moisten and protect the inside of the body constantly being exposed to the elements.
