Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue.
Aside from their distinguishing shape, starfish are most recognized for their remarkable ability to regenerate, or regrow, arms and, in some cases, entire bodies. While most species require the central body to be intact in order to regenerate arms, a few tropical species can grow an entirely new starfish from just a portion of a severed limb. [ 2 ]

A Vichy shower is a form of hydrotherapy that uses a series of shower nozzles that spray large quantities of water over the client while they lie in a shallow wet bed, similar to a massage table, but with drainage for the water. The nozzles may usually be adjusted for height, direction, and temperature to suit the patient's needs.
Inner ear regeneration is the biological process by which the hair cells and supporting cells (i.e. Hensen's cells and Deiters cells) of the ear proliferate (cell proliferation) and regrow after hair cell injury. This process depends on communication between supporting cells and the brain.
Within the sterilizer, water flows as close as possible to the ultraviolet light source. Water pre-filtration is critical as water turbidity lowers UV-C penetration. Many of the better UV sterilizers have long dwell times and limit the space between the UV-C source and the inside wall of the UV sterilizer device. [117] [independent source needed]
