because they do ig
Indeed.
The most common symptom of having a roundworm infestation in the digestive tract would be stomach cramps and asthma-like symptoms. Also you will find roundworms in your stool should you have an infestation.
Annelids
Roundworms are multicellular organisms that possess longitudinal muscles and a complete digestive tract, with a mouth and an anus. Their body plan is characterized by a single body cavity that houses their organs, including their nervous and reproductive systems.
the answer is TRUE
yes
The phylum Annelida includes worms that have a true coelom and a complete digestive tract. Annelids, such as earthworms and marine bristle worms, exhibit segmentation and are known for their well-developed body cavities and digestive systems.
earthworms have clitellum and roundworms dont. earthworms are from the member of phlyum annelidia and roundworms are from the member of the phylum nematoda. Earthworm's have 5 aortic arches(hearts) which roundworms do not ! :)
The anus is the last part of the digestive tract.
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
Roundworms, or nematodes, possess a pseudocoelom, which is a body cavity that is not completely lined by mesoderm. This pseudocoelom serves as a hydrostatic skeleton, providing structural support and facilitating movement through the contraction of muscles. Unlike true coeloms found in other organisms, the pseudocoelom is located between the body wall and the digestive tract, allowing for the efficient transport of nutrients and waste. Overall, the pseudocoelom is integral to the roundworm's physiology and movement.
That wavelike movement of the digestive tract is known as peristalsis.
