Mucous is an innate immunity, it is a powerful early defense mechanism and highly effective physical barriers against microorganisms. Mucous can be found in respiratory tract, gastrointestinal tract, and genitourinary tract.

What is the function of the cilia in the immune system?
When look at the function of cilia in the immune system, you mainly refer to the cilia present in the respiratory system. Cilia, along with mucus, are part of the innate immunity your body has. Mucus in respiratory tubes traps most microbes and dust that get past the nasal filter (nasal hair). Cilia on cells lining the tubes sweep mucus upward and out of the system. !!
Is mucus part of the immune system?
Yes
What is innate immune system?
The Innate Immune System •Acts as the first line of defense •Is nonspecific, meaning it tries to prevent everything from coming in •Is nonadaptive -does not have a memory -will not learn to keep substances out even after repeated exposure •Includes skin, fur, saliva, stomach acid and mucous
What other systems does the immune system work with to maintain homeostasis?
The immune system protects organisms from infection with layered defenses of increasing specificity. In simple terms, physical barriers prevent pathogens such as bacteria and viruses from entering the organism. If a pathogen breaches these barriers, the innate immune system provides an immediate, but non-specific response. Innate immune systems are found in all plants and animals.[11] If pathogens successfully evade the innate response, vertebrates possess a third layer of protection, the adaptive immune system, which is activated by the innate response. Here, the immune system adapts its response during an infection to improve its recognition of the pathogen. This improved response is then retained after the pathogen has been eliminated, in the form of an immunological memory, and allows the adaptive immune system to mount faster and stronger attacks each time this pathogen is encountered.[12]Both innate and adaptive immunity depend on the ability of the immune system to distinguish between self and non-self molecules. In immunology, self molecules are those components of an organism's body that can be distinguished from foreign substances by the immune system.[13] Conversely, non-self molecules are those recognized as foreign molecules. One class of non-self molecules are called antigens (short for antibody generators) and are defined as substances that bind to specific immune receptors and elicit an immune response.
How does the immune system work to prevent pathogens from causing disease in the body?
Not exactly, at least not the immune system most know.In the acquired immune system, a disease enters your body and starts making you feel ill. Your immune system can now destroy this disease because it is in you and it has sensed it. Sometimes diseases are sensed so quickly and the body is already ready for it (due to memory b-cells)that you never feel it. This often happens with the chicken poxs.However the innate immune system can completely prevent certain diseases. Your innate immune system is made up of your skin, your digestive track (primarily the stomach and its acid), and mucus membranes (like inside your nose and lungs). Those systems can block diseases and send them away before they fully enter the body (cool facts, the space in your lungs and your digestive system are not considered "inside the body" - that's right, there is basically a hole going right through your person.)
How does nose and mucus prevent pathogens from entering?
Mucus that are present in body contains macrophages and phagocytes and it acts as first line of defense in our immune system.
What is the difference between innate immunity and adaptive immunity?
Innate is non-specific. It includes the first and second lines of defense. The first line of defense contains the skin, mucus membranes, and normal micro-biota. The second line contains the complement system, phagocytosis, fever, and inflammation.Adaptive is specific. It includes the third line of defense. The third line of defense contains B cells, which make antibodies, and T cells, which kill the target pathogen, and encourages phagocytosis.There is a huge difference between innate and adaptive immunity. Innate immunity is one that is triggered as soon an antigen gets into the body. As for the adaptive, its has to be specific and will allow be introduced once the antigen is recognized.
What system protects the body?
The immune systems protects the body from viruses. First you have your physical barriers like your skin, tears, hair and mucus then you have your immune system which are white blood cells and pus.
How does the immunity system defend against STDs?
Your immune system defends against STD's with structural defenses like gastric juices and the mucus linings. For more info on the parts of the immune system follow the related question.
What 3 things protect the immune system from infections before entering the body?
mucus in your nostrils, your skin, hair in your nose
What protects your body from infectious diseases?
You have the immune system to protect you from the infectious diseases. You have two types of immunity. Cell mediated and humeral type.
Why does your nose stuff up when you get sick?
That would be you immune system triggering your mucus membranes to expel pathogens in your nose out of your nose with your snot.
