|
Refers to the concentration of particles in a solution |
Tonicity of Body fluids |
|
|
|
Body fluids comparable with 0.9% NaCl |
ISOTONIC |
|
|
|
fluids have a higher or greater concentration of solutes (usually sodium) compared with plasma; ex. Is 3% NaCl |
HYPERTONIC |
|
|
|
fluids have a lesser or lower solute concentration than plasma; ex. Is 0.45%, 0.33% NaCL solution |
HYPOTONIC |
|
|
|
fluids have a lesser or lower solute concentration than plasma; ex. Is 0.45%, 0.33% NaCL solution |
HYPOTONIC |
|
|
|
Specialized neurons in the hypothalamus Highly sensitive to serum osmolality Triggers thirst promoting increased fluid intake Also sensitive to change in BV & BP through the info relayed by baroreceptors (stretch) A decreased in BV by 10% Systolic BP falls below 90 mmHg Right Atrium (RA) is underfilled – low venous return
|
Osmoreceptors |
|
|
|
osmoreceptors stimulates hypothalamus to synthesize ADH (from hypothalamus, posterior pituitary gland) |
Increased osmolality |
|
|
|
osmoreceptors stimulates hypothalamus to synthesize ADH (from hypothalamus, posterior pituitary gland) |
Increased osmolality |
|
|
|
ADH is inhibited |
Decreased osmolality |
|
|
|
a critical regulator of blood volume, electrolyte balance, and systemic vascular resistance |
renin-angiotensin-aldosterone system (RAAS) |
