Immune System

The video explores the immune system, highlighting its three lines of defense: the non-specific first line (skin and mucous membranes), the second line (inflammatory response and complement system), and the specific third line (adaptive immunity). It details cell-mediated and humoral responses, emphasizing the roles of cytotoxic T cells and B cells. The importance of memory cells and vaccines in long-term immunity is also discussed.
