Describe how flatworms maintain water balance

http://cornercanyonbiology.weebly.com/uploads/1/7/0/7/17070906/excretion_-_textbook.doc WebPlanaria are flatworms that live in fresh water. Their excretory system consists of two tubules connected to a highly branched duct system. The cells in the tubules are called flame cells (or protonephridia) because they have a cluster of cilia that looks like a flickering flame when viewed under the microscope, as illustrated in Figure 2a.

WebAug 26, 2010 · Flatworms have an excretory system with a network of tubules throughout the body that open to the environment and nearby flame cells, whose cilia beat to direct waste fluids concentrated in the tubules out of the body. The system is responsible for regulation of dissolved salts and excretion of nitrogenous wastes. WebOsmoregulation is the process of maintaining salt and water balance ( osmotic balance) across membranes within the body. The fluids inside and surrounding cells are composed of water, electrolytes, and nonelectrolytes. An electrolyte is a compound that dissociates into ions when dissolved in water. embroidery creations llc https://footprintsholistic.com

WebOct 13, 2010 · How flatworms maintain water balance? They excrete water through the use of protonephridia. 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. 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. embroidery cedar city utah

WebBecause flame cells move water out of the body, they keep flatworm cells from becoming waterlogged. In addition to the action of flame cells, flatworms also excrete waste prod- ucts and maintain homeostatic water balance through their mouths. Simple organ systems, such Figure 25.2 as the excretory and nervous systems, are found in flatworms. 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.
