resorbiert

Resorbiert is the past participle of the verb resorbieren, used in biology and medicine to describe the uptake or dissolution of material by cells or tissues. The term covers processes in which substances are removed from one compartment and returned to another, or tissue is broken down and its components reused. In German scientific language, resorbieren is distinguished from absorption in the sense of uptake from the external environment, and from secretion.

In bone physiology, resorption refers to the breakdown of mineralized bone matrix by osteoclasts, releasing calcium and other minerals into the bloodstream. It is a key part of bone remodeling, a balance with bone formation by osteoblasts. Disproportionate resorption can lead to bone loss and diseases such as osteoporosis or osteolysis. Resorption can be observed in dental and skeletal tissues as well, and may be physiologic during growth or tooth eruption, or pathologic after trauma or inflammatory damage.

In renal and intestinal physiology, resorption can describe the reabsorption or Rückresorption of substances from tubular filtrate or gut lumen back into the bloodstream. In the kidney, essential solutes like glucose, amino acids, and bicarbonate, as well as water, are reabsorbed to conserve nutrients and fluids. In the intestines, resorption refers to the uptake of nutrients and minerals from digested food.

Pathological resorption includes processes such as external or internal dental resorption, and bone resorption due to inflammatory or malignant conditions. The rate and location of resorption influence tissue integrity and treatment decisions.

Etymologically, resorbieren traces to Latin resorbere, meaning to swallow back or absorb again. The form resorbiert is commonly used in scientific and clinical German texts.
