Reabsorbní

Reabsorbní is a term used in biology and medicine to describe the process by which a substance is taken back into the body's tissues or fluids after it has been released or filtered. This process is crucial for maintaining homeostasis and conserving essential materials within the organism.

In the kidneys, for example, reabsorbní is a key function of the nephrons. As blood is filtered to remove waste products, the kidneys selectively reabsorb useful substances such as glucose, amino acids, water, and electrolytes back into the bloodstream. This prevents the loss of these vital components from the body.

Similarly, in the digestive system, reabsorbní occurs in the intestines, where nutrients from digested food are absorbed into the bloodstream. The body also reabsorbs water in the large intestine to prevent dehydration.

Beyond physiological processes, reabsorbní can also refer to the absorption of foreign materials by cells, such as the reabsorbní of bone by osteoclasts during bone remodeling, or the reabsorbní of inflammatory exudates. The term highlights the dynamic nature of biological systems, where substances are continuously being exchanged and recycled. Understanding reabsorbní is fundamental to comprehending many bodily functions and pathological conditions.
