No, the small openings on a sponge are called ostia. Setae are bristles or hair-like structures found on some invertebrates like worms or arthropods that help with movement or sensory functions.
In sponges, waste and oxygen move in and out of cells primarily through a process called diffusion. Water is drawn into the sponge's body through small openings called ostia, allowing oxygen and nutrients to dissolve in the water and enter the cells. Simultaneously, waste products are expelled from the cells into the surrounding water, which is then expelled through larger openings called oscula. This continuous flow of water facilitates the exchange of gases and waste, sustaining the sponge's cellular functions.
They are called stomata, tiny holes that regulate the intake/output of gas, such as carbon dioxide and oxygen.
The opening of the crust where magma is allowed to reach to the surface is called a fault line.
The surface of the orange puffball sponge is covered with small pores that filter small particles of food from the water that passes through them. Each sponge has flagella that help move the water through the sponge.
The paranasal sinuses drain into the nasal cavity through small openings called ostia. These openings allow mucus and other secretions to flow from the sinuses into the nasal passages where they can be cleared by the body.
Ostium.
The body of a sponge is covered in tiny openings called pores. These pores allow water to flow in and out of the sponge, which helps the sponge filter out food particles and oxygen from the surrounding water.
The small bristles on earthworms are called setae. The setae are small spines which are projected from the body wall by muscles to act as anchors in the surface that the worm is moving along. The muscle can also retract the setae when it is not required.
Small pores of sponges are called ostia through which water enters while a large pore through which water exits is called osculum .
They are called stomata, openings or pores in the epidermis of leaves.

The setae are small spines which are projected from the body wall by muscles to act as anchors in the surface that the worm is moving along. The muscle can also retract the setae The circular muscles contract and expand in co-ordination with the longitudinal muscle in series such as that if the posterior muscle are expanded and the anterior circular muscles are contracted the worm pushes and stretches its front end forward. The anterior muscles then expand to anchor its front end by use of the setae and the rear end is pulled forward. All this happens in a smooth and rhythmic motion.

Setae are small, bristle-like structures found on the bodies of certain animals, such as worms and insects. They are often used for various functions including movement, sensory perception, and defense.

The bristles along the body of an earthworm are called the Setae, they are used as anchors as the earthworm moves along.Read more: What_do_the_bristles_on_the_underside_of_the_earthworm's_body_do
