    Our immune system behaviors are greatly similar to how a medieval castle works. All the castles have a huge wall surrounding and protecting the inner parts of the castle. This is very alike to our skin which surround our body as a physical barrier to pathogens (Nowicky 945). Pathogen literally means the viruses and other microorganisms that cause diseases. In this case, we can think of them as invaders of the castle (Nowicky 941). No matter how solid and how stable a wall is, there’s always holes to it, and some of the holes on our body are the nostrils, eyes, mouth,etc which make them vulnerable target (Nowicky 945).
    Two of our most dangerous enemies are the viruses and bacteria. These two pathogens are greatly different but also somewhat similar. Some differences include bacteria being a single-cell organism and virus is just a piece of DNA that floats around and needs a host to replicate. Both of these are harmful but some of the bacteria are actually helpful to us humans. The one big similar between the two is that both of them doesn’t have a nucleus.

    Fever and Inflammation
    Once we get a fever or an inflammation, we most of the times don’t like it because we feel weird and out of ordinary but these two events are actually a signal that your immunity is working. Fever is a sudden increase in temperature of your body. A slight fever helps speed up the process of maturation of white cells so these cells can fight the invading pathogens. While low fever is helpful, high fever can cause great damages to your body and can even kill you. Fever is also an example of a break up of the homeostasis caused by pathogens (Nowicky 951). In the case of inflammation, from an outside view, inflammation looks like a big swellings accompany with pain, redness,etc but from a zoom-in view, the blood vessels are spreading out to make ways for the white blood cells to the infected area (Nowicky 950).

    Looking at the picture in the left, the neuron cell looks like an antenna; the tree branches-like extension out of the cell body are call __Dendrites__, Its only job is to receive the messages form neighboring cells(Nowicki 876) Received the message, the cell send it through the __axon__ covering by the myelin sheath and when it reach the ending tip of the axon which is calls terminal, the message will be send to another neuron cell. *Neuron cells are very unique, “Unlike other cells, neurons cannot replace themselves. Damage to neurons is permanent” (Articles)

    The nervous system is made out of 2 parts; the Central Nervous system (CNS) and Peripheral nervous system (PNS). The CNS only compose of the brain and the spiral core, it acts like headquarter for the nervous system for itonly receives, judges and sends command to the PNS (Nowicki 885) On the other hand, PNS is only a series of nerves that connects to CNS and through out the whole body, its jobs are to detect __stimulus__ inside and outside the body using Sensory neuron and report back to the CNS for respond (Nowicki 875) When received the message, a specific neuron from CNS calls motor neuron will carry out the command from the CNS to targeted muscle or organs and base on the situation, each respond will be different (Nowicki 885) Although there is one special respond, called Reflex arcs; it responds almost immediately when receptors make contact with outside influence, the reason for this is because it only need to travel to the spiral core and to receive unlike other which have to go all the way to the brain.
