WebOsmoregulation means the physiological processes that an organism uses to maintain water balance; that is, to compensate for water loss, avoid excess water gain, and maintain the proper osmotic concentration (osmolarity) of the body fluids. http://cornercanyonbiology.weebly.com/uploads/1/7/0/7/17070906/excretion_-_textbook.doc
WebAug 13, 2024 · Water passively follows the sodium. To restore balance, the sodium-potassium pump transfers sodium back to the extracellular fluid and water follows. Every cycle of the sodium-potassium pump involves the movement of three sodium ions out of a cell, in exchange for two potassium ions into a cell. http://www.wedgwoodsci.com/uploads/5/9/3/1/5931632/ch27.4_wkst__modified_.rtf
WebThe solutes in body fluids are mainly mineral salts and sugars, and osmotic regulation is the process by which the mineral salts and water are kept in balance. … WebOsmotic regulation is the maintenance of the normal concentration of the body fluids; i.e., the total concentration of all dissolved substances (solutes) that would exert osmotic pressure against a membrane impermeable to them. Osmotic regulation controls the amount of water in the body fluids relative to the amount of osmotically active solutes.
WebMovement in some flatworms is controlled by longitudinal, circular, and oblique layers of muscle. Others move along slime trails by the beating of epidermal cilia. The development of directional movement is correlated with cephalization.
