Close-up of two dog hookworms (Ancylostoma caninum) attached to intestinal mucosa. Barely visible larvae penetrate the skin (often through bare feet), are carried to the lungs, travel through the respiratory tract to the mouth, are swallowed, and eventually reach the small intestine. This journey takes about a week.
