water
The collecting duct is responsible for reabsorbing water in response to antidiuretic hormone (ADH). When water is reabsorbed, urea becomes more concentrated in the filtrate that remains in the collecting duct, leading to an increase in its concentration.
# Water is reabsorbed all along the nephron. # Urine becomes hypertonic (salty) because of the loop of Henle and the collecting duct. # Loop of Henle # The descending limb of the loop of Henle can't absorb salt, and the ascending limb can't absorb water. # Salt passively diffuses out of the lower portion of the ascending limb. # The upper part of ascending limb actively transports salt into tissue of the renal medulla. # Increase in salt in the direction of the inner medulla. # Urea leaks from the lower portion of collecting duct and contributes to a high solute (salt) concentration. # Water leaves descending limb of the loop of Henle, returning to the blood. # Urine is hypertonic to blood.
Normal Saline Solution in 5% Dextrose or D5NSS is a hypertonic solution. It can be used for the temporary treatment of shock if plasma expanders are not available. However, do not administer this IV for clients with cardiac or renal conditions.
Try it yourself !
Plant cells plasmolyze when immersed in a hypertonic solution when the cell wall detaches under high pressure causing water to be lost. The more solutes a cell has, the less water becomes available.
When the concentration of solutes is more, it becomes a hyper-tonic solution. Salt can act like a solute in this case.
This process is called phosphorylation.
It becomes duplicated.

The second element in a cover molecule is named using the element's root name and the suffix "-ide." For example, oxygen becomes oxide, sulfur becomes sulfide, and chlorine becomes chloride.
Antidiuretic Hormone is made in hypothalamus (posterior pituitary gland). Stimulated by dehydration and increased blood osmosis. It acts on the collecting duct of nephron to increase amount of aquaporins, thus increasing water permeability. When increased water is reabsorbed, blood osmolarity decreases. Therefore the urine becomes more concentrated.
