Substances are moved through a filter by a process called filtration. Filtration works by using a barrier (the filter) that allows certain particles to pass through while blocking others based on differences in size, shape, or solubility. This separation process relies on a pressure gradient to drive the movement of substances across the filter.
Substances that are small enough to pass through the pores of the filter paper will do so. This typically includes liquids and dissolved substances, while larger particles and solids are left behind on the filter paper.
The process is called filtration. It involves passing a mixture through a porous material, like filter paper or a filter membrane. The dissolved substances are trapped on the filter, while the solvent passes through.
Filtration uses pressure to move a liquid through a semi-permeable membrane. Think of a coffee maker, where the hot water is pulled through coffee grounds and a filter stops most of the particles from ending up in the pot. The smaller particles are dissolved, so they pass through the filter. The larger ones are not dissolved so they stay behind as the used up coffee grounds that get thrown away.
The particle that separates a substance from a mixture is called a filter. This can be a physical barrier, such as a sieve or filter paper, that allows smaller particles to pass through while trapping the larger substance particles to separate them from the mixture.

free liquids
Filtrate is made by passing a liquid through a filter, such as filter paper or a membrane, to separate solid components from the liquid. The solid substances are retained by the filter while the liquid, along with any dissolved substances, passes through as the filtrate.

The filtrate is the liquid that passes through the filter paper and contains the substances that have been filtered. The residue is the solid material that remains on the filter paper after the liquid has passed through.

Insoluble substances can be separated from the solution (liquid) by centrifugation. If a centrifuge is not available, one can just let it sit and allow gravity to do the job. Of course, this will not separate individual substances that are insoluble from each other.
In females, urine is produced by the kidneys, which filter waste products and excess substances from the blood. The urine then travels through the ureters to the bladder, where it is stored until being expelled from the body through the urethra. The female urethra is shorter than the male's, facilitating the elimination of urine.
