WebRegulation of plasma osmolarity is accomplished by varying the amount of water excreted by the kidney. Concentrated hyperosmotic urine is produced when circulating levels of antidiuretic hormone (ADH) are high. ADH, also known as vasopressin (see Chapter 35 ). ADH is released from the posterior pituitary (neurohypophysis) in response to ... Plasma osmolality measures the body's electrolyte–water balance. There are several methods for arriving at this quantity through measurement or calculation. Osmolality and osmolarity are measures that are technically different, but functionally the same for normal use. Whereas osmolality (with an "l") is defined as the number of osmoles (Osm) of solute per kilogram of solvent (osmol/kg or Osm/kg), osmolarity (with an "r") is defined as the number of … great theoretical ideas in computer science https://promotionglobalsolutions.com
