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! :)
through the holes in it
yes
Allow materials to enter and leave the sponge
A sponge doesn't have a body temperature, because a sponge doesn't have a body. But how warm or cold you put the sponge under water or any liquid is the temperature of the sponge.
The sponge uses the choanocytes to move a steady current through its body.
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 large opening at the top of the sponge, where water leaves, is called the osculum. It is responsible for expelling the water and waste products from the sponge's body.
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.

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 .
Human skin is not permeable to water hence water can't enter body through skin .
A sea sponge absorbs water through numerous minute, dermal pores on its body surface known as ostia.
