This involves immune system cells rather than antibodies. They help your body create memories of past defenses against certain threats. When your body sees that invader again, it calls up that memory and sets out to destroy. It is made up of different organs, cells and proteins.

Aside from the nervous system , it is the most complex system in the human body. The immune system also has a few other types of cells on hand to help it work properly. There are phagocytes , which destroy harmful organisms in the body, and cytokines , which send messages within the immune system.

Your white blood cells are like soldiers to protect you from harm.

To answer this question fully would. When functioning properly, the immune system identifies and attacks a variety of threats, including viruses, bacteria and parasites , while distinguishing them from the body’s own healthy tissue. Through highly complex and adaptive processes, a healthy immune system is always at work , protecting you from infections by identifying and destroying harmful microorganisms. Your immune system protects your body from infectious germs. Crucially, it can distinguish our tissue from foreign tissue — self from non-self.

Dead and faulty cells are also recognized and cleared away by the immune system. Inside your body there is an amazing protectio­n mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body.

Vaccines also work on a community level. The types of immune system cells. Of all the cells involved in the immune system, are plasma. This is the non-cellular part of our blood. It stops threats like bacteria or viruses from getting into your body.

It is the second most complex system in the human body - with the nervous system being the first. It recognises the cells that make up your body, and will try to get rid of anything unfamiliar. It destroys germs (bacteria and viruses) and parasites.

But this defence system can also cause problems.

Some immune cells take on all comers, while others are trained on highly specific targets. To work effectively, most immune cells need the cooperation of their comrades. One thing that causes us to really notice our immune system is when it fails for some reason. However it also has some highly specialised defences which give you resistance to particular pathogens. Part of the body’s immune activity involves the complement system, which is a group of specialized molecules that work in a variety of ways to destroy invaders.

The skin is often the first line of defense for foreign pathogens. It acts as a barrier to the inner body and prevents pathogens from entering the body. Immune cells and the substances they make travel through your body to protect it from germs that cause infections.
