Cells adapt by changing their: - Answer 1. size (hypertrophy or atrophy) 2. number (hyperplasia) 3. type (metaplasia) Relationship between hypertrophy and hyperplasia - Answer Hypertrophy occurs in cell types where hyperplasia, the generation of more cells, is uncommon (eg. muscle cells) Why might metaplasia occur? - Answer it occurs in response to chronic irritation and inflammation; one cell type replaces another Define dysplasia - Answer deranged cell growth resulting in varying si...

Secretory IgA is found in the secretions that coat mucus membranes, thereby preventing pathogens from colonizing mucosal surfaces. What are methods that bacteria have evolved to evade or inactivate these antibodies? -IgA proteases that cleaves the antibodies, so that they cannot bind to the pathogen -Antigenic variation, or altering the bacterial structures to which the antibodies bind -Rapid turnover of pili structures to shed any bound antibody How do pathogens penetrate the skin? the...
