Our Amazing Human Body: ... Our Smart Brain et al.

I´m going to talk about the immune system. This system is simply amazing, and as the other systems conforming ourselves is something we can´t live without. It plays the role of basically keeping us protected, and by protecting us it keeps us alive. Protect us from what? Well, of everything that could harm the inside of our bodies, basically speaking of microorganisms. It recognizes the external organisms that enter our bodies and decides to attack the things that could be harmful, like viruses. It is all around our body, in order to protect every part of ourselves, but the mechanisms it uses to defend ourselves have specific parts where these are produced. The most important components of this system are blood, the bone marrow, the lymph and the liver. The thymus is also important, but in the childhood mostly. To describe the size you basically need to say the whole body, cause it is in every part of ourselves. Autoimmune diseases are an illness that means your immune system is not functioning the right way, and it recognizes the parts of your own body as strange, attacking them. A normal autoimmune disease is Diabetes Type 1, in which your immune system attacks the hormone insulin and your body can´t control the the levels of glucose in the blood. Another disease that can alter your immune system is HIV
, and it´s terminal phase better known as AIDS. This makes your immune system weaker and weaker, until the point that your immune system is basically in existent. If you don´t have immune system you could die of a common cold or flu. This makes one think how important is our immune system if it can make us think a cold is no harm for us, while if we don´t have this system something like that could kill us. A way to keep this system functioning at it´s best is to not consume medicament's unless it´s necessary, because this system get´s stronger every time it fights against something. That´s why it´s so important to not auto medicate yourselves. Something very common in our times is to medicate the children every time their sick, and that only makes things worst, because the childhood is an important part to envelope a good immune system.
