Document Summary
2- immune system 1: destroy foreign or non-self matter, utilizes cell recognition, glycocalyx, and the extracellular matrix, functions: Isolate or remove non-microbial foreign substances (pollens, toxins, dust) Immune surveillance- immune system cells circulate in blood, lymphatic"s, and within tissues to detect. Bacteria is unicellular with cell wall, but without: infections: 2 effects of bacterial infection: local tissue damage and bacteria secretes toxin, and if toxin reaches blood can causes systemic infection. Nucleic acids surrounded by protein coat, not really a cell. Must invade host cells to take over their cellular function to replicate virus. 3 outcomes: virus can kill original cell and reproduce, or virus can stay in cell and alternate between dormant and active state (ex. Hermes virus), or it can transform host cell into cancer cell (ex. Hpv infection, causing cervical cancer: 2 classifications of immune response: innate-non-specific. Adaptive immunity-specific lymphocytes recognize foreign matter to determine how to fight it off.
