Connection between plasma osmolarity and total body water in mathematical equation terms?
Plasma Osmolarity =Total Body mOsm - Urine mOs-------------------------------------Total Body Water - Urine Volumeand: Total Body Osmolarity = PLasma Osmolarity x Weight x 0.6 Total Body Water = Weigth x 0.6
What will the kidneys do when increased osmolarity causes the pituitary to release ADH?
draivenarca
Which is the major stimulus for the thirst mechanism?
increased osmolarity of blood plasma
Does caffeine clean THC out of urine?
It does not clean out urine.
The cells of the distal convoluted tubule which monitor changes in urine volume and osmolarity are called what?
macula densa
Is Chocolate a natural diuretic?
Chocolate contains Theobromine. As with caffeine, theobromine can cause sleeplessness, tremors, restlessness, anxiety, as well as contribute to increased production of urine.
Would the invasion of a cell by viruses increase decrease or have no effect on the osmolarity of a cell?
The invasion of a cell by viruses increases the cell's osmolarity. This occurs because the viruses act like any other particle. As the number of viruses increases, the number of particles in the cells increases as well. This increased particle number gives the cells an increased osmolarity that could eventually lead to cellular lysis.
Can Caffeine be linked to bed wetting?
yes as caffeine increases urine production
Why does one feel thirstier after she or he drink soft-drinks?
Being thirsty is a brain response due to increased blood osmolarity or decreased blood volume. The human body must keep its blood osmolarity close to 300 mOsms in order to function properly. If it is increased or the blood volume is decreased the brain will release hormones such as ADH(antidiuretic hormone- to save water) and will trigger a thirst response in the brain. Soft-drinks as opposed to water, have an increased osmolarity and therefore cannot lower your blood osmolarity to the same degree as water and therefore do not relieve your thirst. Hope that helps
