this presentation topic is from physiology.

2. ANMOL JILANI

3.  It is the measure of solute concentration,
defined as the number of osmoles of solute
per litre of solution.
 Normal Value:
300mOsm/L

4.  Regulation of ECF osmolarity & sodium
concentration are closely related.
 Osmolarity must be precisely controlled
because they determine the distribution of
fluid between intracellular and extracellular
compartment.

5. ADH-hormone
(Antidiuretic Hormone)
Also called vasopressin
Thirst Mechanism
Aldosterone-
hormone
Angiotensin II-
peptide

9.  Many of same factors that stimulate ADH
secretion also increase thirst,which is
defined as the concious desire for water.

10. Dehydration
Osmolarity
Stimulus to thirst center
Water intake
