Percolation
Percolation
Percolation (/pɜːrkəˈleɪʃən/), from the Latin percolare, meaning "to filter" or "trickle through", is a term used in various fields of study including physics, geology, and medicine. In the medical field, percolation refers to the process of a liquid slowly passing through a filter. It's a way to purify liquids and can be compared to the functioning of kidneys in the human body.
Etymology
The term "percolation" comes from the Latin word percolare, which means "to filter" or "trickle through". It was first used in the English language in the early 17th century.
Medical Usage
In medicine, percolation is often used to describe the process of fluid, especially blood, moving through the vessels or other channels in an organism's body. This process is vital for the distribution of nutrients and the removal of waste products.
For example, in the kidney, percolation is a crucial process that allows the filtration of blood, removing waste products and excess substances to form urine. This process is facilitated by the glomerulus, a network of tiny blood vessels in the kidney.
