Jellyfish have a simple digestive system. They have a digestive cavity with cells lining the wall that carry out the digestive function.

I am pretty sure they have simple but very complex digestive systems
A gastrovascular cavity in a jellyfish serves as both a digestive and circulatory system. It is a central cavity where food is digested and nutrients are distributed throughout the jellyfish's body. The cavity is lined with cells that secrete digestive enzymes to break down food, allowing for nutrient absorption. This structure is crucial for the jellyfish's simple body plan, as it lacks a complex circulatory system.
Yes
No, a jellyfish does not have a two-way digestive system. Instead, it has a simple gastrovascular cavity with a single opening that serves both as a mouth and an anus. Food enters the cavity for digestion, and waste is expelled through the same opening. This type of digestive system is characteristic of simpler organisms.
No.
Jellyfish and sea anemones do not have a stomach. They have a simple digestive system that allows them to directly absorb nutrients through their body walls.
Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems.
A human nervous system is much more complex. Unlike a human a jellyfish does not have a central nervous system.
Cnidarians, such as jellyfish and sea anemones, have a simple digestive system with a single opening that serves as both mouth and anus, leading to a central gastrovascular cavity where digestion occurs. In contrast, humans possess a more complex digestive system with a separate mouth and anus, involving a long, tubular gastrointestinal tract that facilitates specialized processes for digestion and nutrient absorption. Additionally, cnidarians primarily rely on extracellular digestion in their gastrovascular cavity, while humans utilize both mechanical and chemical digestion throughout their digestive tract.
Cnidarians accomplish digestion using a gastrovascular cavity, which serves both digestive and circulatory functions. Food is taken in through a single opening, where it is digested extracellularly, and the nutrients are then absorbed by the surrounding cells. This simple body plan allows cnidarians, such as jellyfish and sea anemones, to efficiently process their food without a complex digestive system.
You do not need any simple sugar in your diet. Your digestive system turns complex carbohydrates into simple sugar. When you eat a potato or a serving of corn, your body will turn it into simple sugar.
