They say water goes straight through you when you drink it if thats the case what does it go through in the body?
Water is absorbed into the intercellular space by diffusion down an osmotic gradient.The intestine can absorb water into blood even when the osmolarity in the lumen is higher than osmolarity of blood.
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
What causes vasopressin increase?
yea,by retention water ,it increase blood volume,which ultimately increase blood pressure..
Does water flow from Low Osmolarity to High Osmolarity?
yes, water flows from low osmolarity to high osmolarity when two solutiona are separated by a semi-permeable membrane till the solutions on either side of the membrane attains equal osmolarity.
What is the ultimate hypotonic solution?
Solution that has lower osmolarity than blood when administering to patient *water leaves the blood and other ecf areas *and enters the cell
What is high plasma osmolality?
This is when you have a high concentration of solute (ie. Na) in your blood in contrast to a low concentration of water in the blood.
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
Will water intake effect human blood volume?
For the short term and with reasonable amounts of water, ingested water will increase blood volume only transiently. However if there is kidney or cardiac problems or in cases where massive amounts of water is ingested the increase in volume plus the decrease in osmolarity of the blood is fatal.
How does hypoglycemia lead to hyponatremia?
when you have high levels of glucose in the blood (hyperglycaemia) this will draw water out of cells due to the increase in osmolarity. With increased water in to the extracellular fluid it will decrease the concentration of sodium (hyponatraemia)
What help to restore homeostasis in someone with water intoxication?
The reabsorption of salts and ions into the blood after passing through the kidneys.
Which hormone is released to preserve water when serum osmolarity increases?
ADH
How do A.D.H and R.A.A.S work together in maintaining osmoregulatory homeostasis?
ADH monitors appropriate osmolarity by reabsorption of water, and RAAS maintains osmolarity by stimulating Na+ reabsorption.
