  1. Objective: Immune and Lymphatic System

    Hey Gabriel,

    Thank you for your post. I like your expressive drawing and the colors that you used. The picture shows the aggregation of bacteria based on an antigen-antibody reaction. Antibodies bind relatively specifically with their antigen-binding region using the key-lock principle. Aggulation arises from the ability of antibodies (in blue) to bind to more than one antigen-binding site. In the process, antigen-carrying particles such as bacteria (in yellow) stick together or clump together.
