    • the larvae mature in the lungs and then move up the trachea and then swollowed
    • and reproduced and thrive in the small intestine, a mature female can lay 200
    • thousand eggs per day. the eggs pass out of the body with each defication.
  8. Beef Tapeworm Life-Cycle:Encysted beef tapeworm larvae are ingested by man,
    • the larvae are released from their cysts and attach in the small intestine where
    • they mature and reproduce, their eggs pass out of the bodu with each defication,
    • cattle eat grass contaminated with eggs, the larvae hatch and live in the muscles
    • of the cattle
