Ancylostoma duodenale, commonly known as the Old World hookworm, is a parasitic worm that resides in the small intestine of its host as part of its life cycle. Here are the steps of its life cycle:

1. The life cycle of Ancylostoma duodenale begins when the eggs are passed in the feces of the infected host.

2. These eggs hatch in the soil and develop into infective larvae within a week.

3. The infective larvae can penetrate the skin of a new host, usually through the feet when walking barefoot on contaminated soil.

4. Once inside the new host, the larvae travel through the bloodstream to the lungs.

5. The larvae are then coughed up and swallowed, which leads them to the small intestine.

6. In the small intestine, the larvae mature into adult worms and attach themselves to the intestinal wall, where they feed on the host's blood.

7. The adult worms produce eggs that are passed in the feces, completing the life cycle and potentially starting a new one if the conditions are right.
