JudyFiltration is the movement of substances from blood into the kidney tubules, while reabsorption is the movement of substances from the kidney tubules back into the blood. Filtration occurs at the glomerulus, where small molecules are forced out of the blood and into the tubules. Reabsorption occurs throughout the tubules, allowing the body to retain essential substances like water, glucose, and electrolytes.

What is the difference between filtration to evaporation?
Filtration is a process used to separate solids from liquids by passing the mixture through a filter, while evaporation is a process where a liquid is converted into a gas or vapor by heating. Filtration separates components based on size, while evaporation separates components based on their boiling points.
When gravity filtration is too slow what is the alternative filtration?
When gravity filtration is too slow, an alternative method is vacuum filtration. In vacuum filtration, a vacuum pump is used to create a pressure difference between the filter flask and the receiving flask, which improves the speed of the filtration process by helping to pull the liquid through the filter paper more quickly.
What is the difference between filtration and ultrafiltration?
Filtration is a process of separating solids from fluids by passing through a porous material, while ultrafiltration is a specific type of filtration that uses a membrane with very small pores to separate solutes based on their size and molecular weight. Ultrafiltration is typically used for finer separations and can remove smaller particles than traditional filtration methods.
What is the difference between a buchner flask filter flask and side-arm flask?
A Buchner flask is a flat-bottomed flask used in filtration setups with a sidearm to attach a vacuum source. A filter flask has a sidearm with an angled neck to connect to a vacuum pump for filtration. A side-arm flask typically has a single sidearm used for connecting to other glassware or apparatus.
What is the difference between Hirsch funnel and Buchner funnel?
A Hirsch funnel is cylindrical and typically used for vacuum filtration of small volumes with the help of filter paper. A Buchner funnel is a flat-bottomed funnel with a porous porcelain or glass disc used for vacuum filtration of larger volumes, sometimes without the need for filter paper.
