Digestion of another animal inside us and OTHER mammals
Ancylostoma caninum
Hookworms are a number of bloodsucking parasites that usually are hatched and live inside the intestines of humans and other mammals. They attach their hooks to the walls of the intestine and get their food from their. They start their lives in eggs on the outside of their host usually in the soil or somewhere on the ground. These eggs can easily penetrate the skin and can get in the human body quickly many times through the sole of the foot. The larvae move from the place where they enter the body, through the blood stream where they enter the lungs. From the lungs, the larvae are moved up to the mouth from mucus and then enter the digestive system. They then hatch in the small intestine where they hook to the walls of the intestine and suck the blood out of certain vessels.
Hookworms are very similar to other nematodes, but they have one major difference which changes the way their whole system works. They take in the food/ blood from the hooks and out in the head of the hookworm. The food passes through the pharynx and into the intestine. The unique thing about hookworms is that there is no coelum cavity or anything to push down the food from the mouth. It must depend on outside forces and its own movement to make the food go down the intestine and through the digestive tract. As the needed nutrients from the blood are passed out through the pores in the intestine to where it is needed in the animal, the waste is released from the body through the anus, opposite the mouth on the other end of the body.
