Question

Name two processes that take place in the kidneys and discuss each briedly?

Answer 1

Filtration, reabsorption, and secretion.

Explanation:

I'm going to infer that 'briedly' is a mistyped 'briefly.' So, here you go:

There are actually three main processes to the kidneys, take from each what you like to help answer your question.

Filtration, reabsorption, and secretion.

Filtration: Filtering masses of water and solutes out of the plasma in blood. This process is driven by hydraulic pressure in the capillaries of the glomerulus.

Reabsorption: Moving water/ solutes back into blood's plasma. There are two types of reabsorption; bulk and regulated. Bulk reabsorption has to do with transporting important solutes actively out of the proximal tubule and for sodium to be reabsorbed in the loop of Henle.

Secretion: The kidney's (in the tubules) secrete additional substances that need to go into the tubular fluid, this usually helps eliminating toxins and is essential for plasma concentration/ balancing pH.
