    Macrophage: alert rest of immune system of invaders(bacteria or viruses)
    T cells: the "T" comes from the Thymus where the t cell matures. two types; helper t cells and killer t cells.
    ...
    preforms antigen present
    Bone marrow: every
    presentation.
    Antigen Presentation: where mkacrophage or dendritic
    cell involved"eats" invader and gives piece of the invader called teh antigen to he helper t cell so that so that it can recognize it and activate the b and killer t cells.
    killer t cell: attacks ankd kills cells infecting the body and the cancer cells.
    B cells: take teh antigen from the helper t cell and connects to it so that it sends off a signal to the rest of body, and then int produces protein by hleper t cell to fully activate then splits
    in two cells: plasma cells and b memory cells.
    Plasma cell: produces antibodies that respond to antigen adn are released so they can find virus and kill it.
    Memory cells: have
    a person’s immune system initially came fromlong life span so it can remember "intruders" so that the bone marrow makes B2nd time you are affected the t and b cells can activate faster and the virus or bacteria is wiped out befoer the human has any symptoms.

Well, will you really love you hair so much when you find out that it’s dead cells? Or that when you bite your nails, you’re basically biting a shield? And did you know that your skin is an organ? In fact, it’s the largest organ? Well, all those statements are true. Hair, nails and skin are all part of the integumentary system, the ‘shell’ of the human.
