Storyboard for Bio-med (Brendan, Ana, Aubrey)
This storyboard does not have a description.
Teacher why do we have nose hairs and other things like mucus?
Wow that's really cool!
We have nose hairs and mucus to stop disease from getting into our body. The nose hairs filter out the bad things while the mucus traps them.
These things are part of our nonspecific defense, but there is one more piece to that and that is the skin. Our skin's job is to not let the invaders in at all.
Is there a specific defense that is used deeper inside our body?
Yes there is, but it can be used anywhere inside our body. This includes the inflammation, B-Cells, T-Cells, phagocytes, and antibodies. These are the specific defense that you guys ask about.
I don't have much time left so I have to go through it fast, so no more questions.
Well what does all this stuff do?
Inflammation causes white blood cells to be released into the blood or affected areas to protect our body. These white blood cells are the phagocytes I mentioned and these engulf the invaders. T-Cells act as a messenger to our immune system so it can initiate the proper response. The B-Cells create Y shaped proteins called antibodies that identify and assist in removing antigens and other targets like bacteria and viruses.
I'm pretty sure that is all of it, and before you ask I can explain antigens next time we meet.
