The digestive tract and reproductive organs of an Ascaris are free floating within the body and do not attach to the body wall. Ascaris do not have any other internal organs other than the gut and internal reproductive organs, as breathing and waste excretion are handled externally within the body wall.
The scientific name of ascaris is Ascaris lumbricoides.

Ascaris has a pseudocoelom, which is a body cavity that is partially lined by mesoderm but lacks a full peritoneal lining like a true coelom.
Ascaris is the common scientific name, the common English name is roundworms
The two most visible body systems in Ascaris roundworms are the digestive system, which includes the mouth, pharynx, intestine, and anus for feeding and digesting nutrients, and the reproductive system, which includes the ovary, oviduct, testis, and vas deferens for reproduction.
Ascaris, a genus of parasitic roundworms, exhibits a grade of organization known as "triploblastic" and "coelomate." This means that Ascaris has three germ layers (ectoderm, mesoderm, and endoderm) and possesses a true coelom, which is a fluid-filled body cavity. Additionally, Ascaris features organ-level organization, with specialized organs for reproduction, digestion, and excretion. Its body structure reflects adaptations for a parasitic lifestyle within the host's intestines.
Ascaris feed on nutrients in the small intestine of their host, such as carbohydrates and proteins. They absorb these nutrients from the digested food that passes through the intestines, which can lead to malnutrition in severe cases of infestation.
