Question: What is the inmune sistem? What is it made up of? What is it used for?

Hi Pol Medir!

Basically our immune system is a part of us made up cells specialized to do whatever it takes to keep us healthy. I’m going to direct you to the home page of our zone which says this (see below) in a much better way than I could describe it! But let me know if you have any more questions.

The immune system is made up of structures and processes which protect us from disease.

White blood cells are one of the main components of our defense system. They can fight infections using different strategies: some of them recognise and remember the invading germs, and others eat germs up!

White blood cells are produced in our spleen – an organ which filters blood – inside our bones, and in glands spread throughout our body. Do you sometimes get a sore throat when you have a cold? That is because the glands in your throat are producing white blood cells to fight the germ causing your cold!

The five scientists in this zone are looking at how the immune system works, searching for ways to improve it or help it fight unwanted pathogens. There is a scientist designing vaccines to protect us from dangerous bacteria, another one looking at how bacterias can leak from the gut into the blood. There is also a scientist studying the cells that fight against bugs and viruses, and another one using computer models to understand our immune system better. Finally, there is a scientist trying to avoid that our immune system attacks transplant organs.
