The immune system
Coughing and sneezing are your body's way of getting rid of microorganisms from our bodies.
Light consists of various wavelengths, with UV radiation being a subset of the light spectrum. UV radiation is more energetic and can damage our skin cells and DNA when overexposed. Our bodies have natural defenses against visible light, while UV radiation can break down these defenses and cause harm.
Microzoology is the study of microorganisms in animals, including protozoa and other microscopic organisms that can live inside or on the bodies of animals. It focuses on the interaction between these microorganisms and their animal hosts, their impact on health and disease, and their ecological roles in various ecosystems.
Any microorganism can make us ill once it colonizes. For example, on your skin right now are varieties of bacteria along with yeast. This normal flora does not make us ill (usually). But if something gets out of balance, the bacteria or yeast can begin to multiply. Our bodies initially try to wall off the infection if it is inside our bodies; on the skin, it is harder. If our defenses are low or we cannot fight it off, an infection is well underway.
Our bodies have many natural defences. Our main internal defence would be our immune system which helps combat bacterial and viral diseases. Our main external defence would be our skin which protects our body and prevents pathogens and microbes from entering our bodies. Hope This Helps :D
Many different diseases can cause mass production on mucus it's a bodies natural defence mechanism against microorganisms
Your body's most important nonspecific defense is the skin. Other nonspecific defenses include mucus, sweat, and tears.

human bodies
the immune system does aid in protecting your body fight against disease or foreign bodies, but the main soldiers are your white blood cells which surround whatever germ or disease in the body and kills it. The more healthy you are the better your body can defend against these foreign bodies, viruses whatever you call them.
your skin and white cells that kill bacteria
Yes, it dehydrates the body and weakens the bodies defenses.
Vaccinations work by injecting a small amount of a weakened or dead form of the disease you are preventing. This works because the bodies defenses learn how to kill the disease very quickly and can fight it off very easily the next time they encounter it. If you tried to vaccinate a person who is already infected with the disease you are trying to prevent, than you would just be injecting more of the disease into a body that is already fighting the disease off. For most diseases, actually becoming infected with the disease serves as a vaccination in itself. It works the same way, except that the body has a much harder time fighting the disease off, because the microorganisms that cause the disease clearly did not enter the body dead, as is the case with deliberate vaccinations.
Pathogens are disease-causing organisms that invade the body. They include bacteria, viruses, fungi, and parasites. These microorganisms can cause infections and illnesses in their host.
Yes, it's true that our bodies come into contact with millions of microorganisms daily. However, our immune system is able to defend against most of these invaders, keeping us healthy. It's a normal part of our body's interaction with the environment.
With a "live" vaccine, you're given a very small dose of the actual disease virus, or an inactived form of the virus. You become mildly ill, your body develops anti-bodies and helps you get well. If you're ever exposed to the disease again (full-force), your body already has anti-bodies developed and you do not get the disease again.
