How is plasma osmolality maintained
WebThus an osmoreceptor should respond to changes in osmolality of the body fluids but not to changes in body temperature or blood pressure. 5. The carbon dioxide produced by the respiratory activity of the tissues is carried to the lungs by the blood in the pulmonary artery where it is excreted in the expired air. WebOsmoregulation is the process by which the body regulated the osmotic pressure of any organsms fluids in order to keep the homeostasis of the organisms’ water level constant. …
