Kudosnesteistä

Kudosnesteistä refers to a Finnish term that translates to "kudos fluid" or "tissue fluid." It is a general term for the extracellular fluid that bathes the cells of multicellular organisms. This fluid is crucial for maintaining the internal environment of the body and facilitating the exchange of substances between the blood and the cells.

Kudosnesteistä is primarily composed of water, ions, small molecules like nutrients and waste products, and proteins. Its composition is similar to blood plasma but with a significantly lower concentration of proteins. The fluid originates from the blood capillaries, where plasma filters out of the bloodstream into the interstitial spaces. This filtration process is driven by pressure differences across the capillary walls.

The primary function of kudosnesteistä is to act as a medium for transport. It delivers oxygen, nutrients, hormones, and other essential substances to the cells. Simultaneously, it picks up waste products, carbon dioxide, and other metabolic byproducts from the cells for removal from the body. Furthermore, kudosnesteistä plays a vital role in the immune system, transporting white blood cells and antibodies to sites of infection or injury.

The fluid also helps to maintain the shape and integrity of tissues by providing hydrostatic pressure. Excess kudosnesteistä is collected by the lymphatic system, which returns it to the bloodstream. Disruptions in the balance of fluid filtration and drainage can lead to edema, a condition characterized by the accumulation of excess fluid in tissues.
