straight only the small intestine is coiled
No. The small intestine is.
The first portion of the small intestine, the duodenum, is straight. The second portion, the ileum, is coiled.
The second part, the ileum, is coiled.
In earthworms, the digestive organ responsible for digestion and absorption of nutrients is the intestine. The intestine is a long, coiled structure where food is further broken down by enzymes and where the absorption of nutrients into the bloodstream takes place. The presence of typhlosole, a fold in the intestinal wall, increases the surface area for absorption, making the process more efficient.
The small intestine is a coiled tube in which chemical digestion occurs.

The distal coiled portion of the small intestine is called the ileum. It is located between the jejunum and the cecum (the beginning of the large intestine) and is the longest section of the small intestine. The ileum is primarily involved in the absorption of nutrients, especially vitamin B12 and bile salts.
Oh, dude, earthworms totally have a digestive system, just like us! They have a long tube-like digestive tract that includes a mouth, pharynx, esophagus, crop, gizzard, and intestine. So yeah, they do have a small and large intestine, but it's not like they're worrying about fitting into their skinny jeans or anything.
The intestine aids in the digestion. It also absorbs and transfers nutrients and water into the bloodstream.
