Resorption
Resorption
Resorption (pronounced: rih-ZORP-shun) is a biological process that involves the breakdown or destruction of a structure in the body, followed by the absorption of the breakdown products. This process is essential for the maintenance and repair of tissues and for the regulation of body functions.
Etymology
The term "resorption" is derived from the Latin word "resorbere", which means "to swallow back". This reflects the process where the body reabsorbs substances that it has previously secreted or ingested.
Process
Resorption occurs in various parts of the body and involves different types of cells. For example, in the bone, osteoclasts are responsible for bone resorption. They break down the bone tissue, allowing the minerals, such as calcium and phosphate, to be reabsorbed into the bloodstream. This process is crucial for the maintenance of calcium homeostasis in the body.
In the kidney, resorption is carried out by the cells of the renal tubules. They reabsorb water, glucose, and essential ions from the urine, preventing their loss from the body.
