The life cycle of Trichuris trichiura, also known as the whipworm, involves several stages and occurs entirely within the human body. Here is a description of its life cycle:

1. Ingestion of eggs: The life cycle begins when a person ingests the eggs of Trichuris trichiura. These eggs are typically found in contaminated soil or food, especially fruits and vegetables that have been grown in areas with poor sanitation.

2. Hatch in the small intestine: Once the eggs are ingested, they hatch in the small intestine, releasing larvae.

3. Migration to the large intestine: The larvae then migrate to the large intestine, where they mature into adult worms. This migration usually takes about 3 weeks.

4. Adult stage: In the large intestine, the larvae develop into adult whipworms. The adult worms are approximately 3 to 5 centimeters long and have a whip-like appearance, hence the name whipworm.

5. Attachment and feeding: The adult worms attach themselves to the intestinal wall using their thin, thread-like anterior end. They then feed on the blood and tissue fluids of the host, causing damage to the intestinal lining.

6. Egg production: The female whipworms start producing eggs, which are passed out of the body through the feces. Each female worm can lay thousands of eggs per day.

7. Environmental development: Once the eggs are excreted in the feces, they need to develop in the environment before becoming infective. This process usually takes about 2 to 3 weeks.

8. Infective stage: After the eggs have matured in the environment, they become infective. They can survive in the soil for several months, waiting to be ingested by another host.

9. Re-infection: Humans can become re-infected by ingesting the infective eggs, completing the life cycle of Trichuris trichiura.

Overall, the life cycle of Trichuris trichiura takes about 2 to 3 months to complete. The adult worms can live in the human intestine for several years, continuously producing eggs and causing symptoms such as abdominal pain, diarrhea, and anemia.
