1)   What was most interesting or most confusing about the these resources?

            After reading of the article about "Just Skin Deep — Your Immune System at the Surface" how our skin and T cells is helpful which protect our body from infection.In the past, i thought the homeostasis action occur in the internal body system after reading this article i found out that human skin and cell are broadly related to our immune system and it's involved in homeostasis process and in skin diseases are really helpful in the areas of research. Although reading about the skin and cell is complex and caused me confused at the beginning when trying to read more relevant information  it make me more curious about the skin and cell related to our immune system. I am more curious reading about these important and function.I have learned about  how T cells is important and a crucial component of our immune system. These T cell helps to destroyed the infected cell and also help to combat tumor each T-cell is uniquely designed to combat a specific threat.

    Learning about skin and cell is complex, finally I clearly understand about  CD8+ T cells, which called cytotoxic T lymphocytes (Tc) how they played important role for our body. How the cell helps target and destroy cells infected with viruses, bacteria, and even tumor cells and also ensuring the infected cell doesn’t spread the virus. These cell help memorized the specific infection  and repeating attack the specific antigen. T-cells are active role players in the adaptive immune system in our body.CD8+ T-cells very important for our the immune system’s and also important for health and survival.
