Verified step by step guidance

Understand the role of the immune system in recognizing and responding to foreign substances, known as antigens, which contain specific regions called epitopes.

Learn about the different types of cells involved in the adaptive immune response, including B cells, T cells, and plasma cells, each with distinct functions.

Recognize that B cells and T cells are part of the adaptive immune system and are capable of recognizing a vast array of epitopes due to their ability to generate diverse receptors through genetic recombination.

Identify the specific roles of T cells, including T helper cells and T cytotoxic cells, which are crucial for targeting and eliminating infected or cancerous cells.

Understand that plasma cells are derived from B cells and are responsible for producing antibodies, but they do not directly recognize epitopes; instead, they secrete antibodies that bind to specific antigens.
