Water is held in the sponge until it is released.
through yuhr nose .....................lol through the little hole look at it really close

the water goes through a sponge because a sponge has a lot of holes which can be taking in.
through the pores
The movement of water provides a simple mechanism for feeding respiration circulation and excretion.
Sponges are animals and are heterotrophs- they need to take in nutrients and food for energy. The nutrients are carried by the water into the sponge.
When a sponge is submerged in water, the water enters the sponge through the tiny holes in the sponge. The sponge fills up with water, as a balloon fills with air, only not as visibly. When you squeeze the sponge, the water exits that sponge through the tiny holes...exactly the opposite of how it entered! Tada! :)
A sponge takes in water through its pores and in more advanced forms, with canals that move the water to all throughout the sponge. Then the oxygen from the water is used.
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 sponge uses the choanocytes to move a steady current through its body.
tiny "whips" on the cells inside a sponge draw water in through the pores of thesponge. Food is then removed from the water before it leaves through the opening at the top of the sponge .
Water is brought through cilia-lined pores into the hollow cavity of the sponge. As water passes through the pores, the cilia trap oxygen to breathe
"clean" water and "waste" water in a sponge are all the same. Their bodies allow constant flow of water, there is no beginning and end to a sponge; thus technically waste water leaves a sponges body through its many pores.
Osmosis is the movement of water across the cell membrane or the movement of water through diffusion. :)
Oh that's quite simple. Find a sponge and get a bowl. Put the sponge in the water and explain how the pores in the sponge suck in the water as you put pressure on it. As you squeeze it explain that the pores release the water through them.
Facts From : Staight a student ok here are the answers....System TypeSponges SystemMuscular-SkeletalA sponge is a hollow tube with many pores or openings. The skeleton is made of lime or silicon.DigestionA sponge takes in food via the water that flows through the pores.NervousA sponge has a very low level reaction to the world around it and does not have a brain per se.CirculationA sponge has water flow in through the pores. The water contains the food and oxygen the sponge needs.RespirationA sponge takes in water through its pores and in more advanced forms, with canals that move the water to all throughout the sponge. Then the oxygen from the water is used.ReproductionA sponge reproduces by budding and also sexually.ExcretionA sponge has carbon dioxide and other wastes removed as the water moves in and out through the pores.SymmetryA sponge has either radial symmetry or is asymmetrical.ColorationA sponge is white, red, orange, green, yellow, brown, purple, black (colors)
