No, the small intestine is located in the abdominal cavity, not the pelvic cavity. The small intestine is part of the digestive system, where nutrient absorption takes place. The pelvic cavity contains reproductive organs, the urinary bladder, and part of the large intestine.
Marrow cavity does not belong as it is a central hollow area within the bone where bone marrow is located, while the other structures are components of the bone tissue.
The hydra is a classic example. See link below for more information.
Cnidarians do not have a true coelom (body cavity lined with mesoderm). Instead, they have a simple body plan with a central digestive cavity called the gastrovascular cavity. This cavity serves for both digestion and circulation of nutrients.

Digestive System: You may be wondering that the organs in the digestive system are located in the abdominal cavity. True, but the esophagus, the tube that carries food to the stomach is located in the thoracic cavity. The thymus or thyroid gland is also a part of the organs in the pectoral cavity.Baxamusa, Batul Nafisa . "Organs in the Thoracic Cavity." Buzzle. Buzzle.com, n.d. Web. 4 Oct 2012. .
The duodenum is located in the abdominal cavity, which is the largest body cavity in humans and houses many of the major organs of the digestive and reproductive systems.
No, the small intestine is located in the abdominal cavity, not the pelvic cavity. The small intestine is part of the digestive system, where nutrient absorption takes place. The pelvic cavity contains reproductive organs, the urinary bladder, and part of the large intestine.
The digestive space found in a cnidarian is called the gastrovascular cavity. This cavity serves both digestive and circulatory functions, allowing for the distribution of nutrients throughout the organism. It is a central chamber that facilitates the breakdown of food, which is absorbed by the cells lining the cavity. Cnidarians, such as jellyfish and corals, utilize this simple digestive system due to their relatively small size and body structure.

The central nervous system is the brain and spinal cord. It s located in the cranial cavity (brain) and the spine (spinal cord).
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.
