How does tissue structure influence infection susceptibility?
Tissue structure plays a significant role in determining susceptibility to infections. For instance, the integrity of epithelial barriers, such as the skin and mucous membranes, is crucial for preventing pathogen entry. Compromised barriers due to physical damage, inflammation, or underlying diseases can increase infection risk. Additionally, specialized structures like cilia in the respiratory tract help expel pathogens, and their dysfunction can predispose individuals to respiratory infections.
