What are the 3 steps for urine formation?

Answer 1

Filtration

As blood courses through the glomeruli, much of its fluid, containing both useful chemicals and dissolved waste materials, soaks out of the blood through the membranes (by osmosis and diffusion) where it is filtered and then flows into the Bowman's capsule. This process is called glomerular filtration

Reabsorption

by definition, is the movement of substances out of the renal tubules back into the blood capillaries located around the tubules (called the peritubular copillaries). Substances reabsorbed are water, glucose and other nutrients, and sodium (Na+) and other ions

Secretion

In this respect, secretion is reabsorption in reverse. Whereas reabsorption moves substances out of the tubules and into the blood, secretion moves substances out of the blood and into the tubules where they mix with the water and other wastes and are converted into urine.

Answer 2

There are three main processes that result in the formation of urine: filtration, reabsorption, and secretion.

Answer 3

The three physiological processes involved in urine production include: Glomerular filtration, tubular reabsorption and secretion.

Answer 4

There are three main processes that result in the formation of urine: filtration, reabsorption, and secretion.

Answer 5

Answer 8

The formation of urine is: filtration, reabsorption and secretion.
