Write about the life cycle of Ascariasis. Ans. Ingestion is the first step of the lifecycle of Roundworm. In this process the larvae and eggs find their way to the intestine of the human body through direct or indirect contact. Migration is the next step where the eggs of Roundworms hatch inside the small intestine to become larvae. Subsequently, they penetrate the intestinal wall and move to other organs of the body through the bloodstream, especially the lungs. Life Cycle. Embryonated eggs are ingested with food or water and the larvae hatch out in the small intestine. They penetrate the intestinal mucosa to enter the venules or lymphatics and travel to the lungs, where they develop for about 10 days. They then enter the alveoli to be coughed up and swallowed.

The female worm grows up to 35 cm in length and lays approximately 20,000 eggs that are passed out of the human stool into the environment.Life Cycle of Ascaris lumbricoides -The Ascaris Worm begins its journey as a cyst living inside of another plant or animal until the day it is consumed by another animal or human being. -Once consumed the Ascaris worm hatches from its shell and transforms into an adult worm as it makes its way through the circulatory system of its host to where it will eventually stop(most commonly the small intestine) granny flats for rent cannon hillogun iferan oni candlemsi lol 2022espn tenis
