Vedelikevahetus refers to the process of exchanging bodily fluids. In a biological context, this primarily pertains to the movement of water and dissolved substances within an organism and between an organism and its environment. This exchange is fundamental for maintaining homeostasis, the stable internal conditions necessary for life.

Key bodily fluids involved in these exchanges include blood, lymph, interstitial fluid, and intracellular fluid. These fluids transport nutrients, oxygen, hormones, and waste products. For instance, the circulatory system facilitates the exchange of gases and nutrients between the blood and the body's tissues through the interstitial fluid. Similarly, the kidneys play a crucial role in filtering blood and regulating the composition of urine, which is a form of fluid excretion.

In a broader sense, vedelikevahetus can also describe the transfer of liquids in various systems, not strictly biological. This might include industrial processes involving the pumping and filtration of liquids, or even environmental cycles like the water cycle, where water moves between the atmosphere, land, and bodies of water. The efficiency and regulation of vedelikevahetus are vital for the proper functioning of the systems in which they occur. Disruptions to these exchanges can lead to various physiological or systemic problems.
