Ascaris lumbricoides is a nematode worm which leads a parasitic life in the intestine of man. Hence it is an endoparasite.

Body is long and round so that it can easily fit in the lumen of the intestine.
Cuticle covering the body protect the worm from digestive juices secreted in the host’s intestine.
Ascaris also secretes some antienzymes against digestive enzymes of the host.
Papillae present on the lips of the worm help in anchoring to the villi in the intestine.
Worm can ingest tissue of the host and suck the blood from the host.
Digested food of host is absorbed by the surface of the body directly from the host’s intestine.
Worm respires anaerobically in the host’s intestine which is devoid of oxygen.
Millions of eggs are produced ata time for the benefit of survival.
Eggs hatch into juveniles which are present in the environment. Eggs can also be present in the environment.
Infection is direct through contaminated food and water.
