Compensatory growth (organ) kidneys. Along with the kidneys, compensatory growth has also been characterized in a number of other tissues and organs including: A large number of growth factors and hormones are involved with compensatory growth, but the exact mechanism is not fully understood and probably varies between different organs. Nevertheless, angiogenic growth factors which control the growth of blood vessels are particularly important because blood flow significantly determines the maximum growth of an organ. Compensatory growth may also refer to the accelerated growth following a period of slowed growth, particularly as a result of nutrient deprivation. Compensatory growth (organ) Compensatory growth is
Water organ Water organ The water organ or hydraulic organ () (early types are sometimes called hydraulos, hydraulus or hydraula) is a type of pipe organ blown by air, where the power source pushing the air is derived by water from a natural source (e.g. by a waterfall) or by a manual pump. Consequently, the water organ lacks a bellows, blower, or compressor. The hydraulic organ is often confused with the hydraulis. The hydraulis is the name of a Greek instrument created by Ctesibius of Alexandria. The hydraulis has a reservoir of air which is inserted into a cistern of water. The
