They are called spiracles
An internal body-support structure is called a skeleton. It provides support, protection, and structure for the body.
The largest class of sponges is Demospongiae, which includes over 90% of all known sponge species. Their body type is typically characterized by a leuconoid structure, which consists of a complex network of canals and chambers that allows for efficient water flow and filtration.
Sponges belonging to the class Syconoida, such as Sycon ciliatum, are examples of sycons. These sponges have a tubular body structure with choanocytes lining the radial canals, helping in water circulation and filter feeding. Sycons are filter feeders that rely on water flow through their body to capture particles for food.
When the internal body structure of a vehicle is used as a frame, it is called a unibody structure. This design integrates the vehicle's body and frame into a single unit, providing structural strength and reducing weight.

Sponges are invertebrates, meaning they do not have a spine. Sponges are soft fleshy animals that maintain their structure through the fibers in their body and water pressure.
Sponges have no proper body cavity or coelom. However, in the everyday sense of the expression, there is a cavity inside sponges, which is called a spongocoel.
Buds?
Sponges belongs to family of coral reefs. their body is cvered with fibrous matter and the final last layer is covered the hard covering made up of Calcium carbonate. the outer covering of calcium carbonate helps them to protect them selves from their predators

The structural protein found in all sponges is collagen. It provides support and structure to the sponge's body, allowing it to maintain its shape and function.
Rather than calling it as having segmented body, it is more apt to say they have poriferous body that is body with many pores. Sponges are collection of microscopic animals. The body of a sponge has two outer layers separated by an acellular gel layer called the mesohyl. The gel layer has calcium carbonate or spongin protein that gives it the rigid structure.
Sponges do not have hydrostatic skeletons. Instead, they possess a simple body structure supported by a matrix called mesohyl, which contains various cells and skeletal elements like spicules and collagen fibers. This structure provides support and helps maintain the sponge’s shape, but it lacks the fluid-filled cavities characteristic of hydrostatic skeletons found in other animals. Thus, sponges rely on a different mechanism for structural support.
