Which is the major stimulus for the thirst mechanism?
increased osmolarity of blood plasma
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 is the sensory function for water?
You have a thirst centre in the brain. When the osmolarity of the extracellular compartment becomes more, water is drawn out from the cells. The signal is sent to brain and you feel thirst. When ever there is loss of isotonic fluid like happens in cholera, the patient do not complain of thirst. Even with severe dehydration.
What sport-related risk is associated with thirst?
Dehydration
What sports-related risk is associated with thirst?
Dehydration
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 sports related risk is associated with thirst?
Dehydration
What does the term osmolarity means?
Osmolarity, which is also known as osmotic concentration, is the measure of solute concentration. The osmolarity of a solution is usually expressed by Osm/L (pronounced "osmolar").
What is the osmolarity of 2 percent NaCl?
The osmolarity is 4 osmol/L.
Does survismeter measure osmolarity?
The survismeter measures osmolarity by developing a standard calibration between PCI (Physicochemical indicators such as viscosity, surface tension, friccohesity) and known values of osmolarity of some molecule.
What is the formula for osmolarity?
Osmolarity = Molarity x i i = number of particles produced when one formula unit of solute dissolves
What is the osmolarity of peripheral parenteral nutrition?
The osmolarity tends to be less than 600-900 mOsm/L
