, Starling's Law describes how fluids move across
the capillary membrane. There are two major
opposing forces that act to balance each other,
hydrostatic pressure (pushing water out of the
capillaries) and osmotic pressure (including
oncontic pressure, which pushes fluid into the
capillaries).
What is Starling's Law of
Capillary forces?
Both electrolytes and proteins (oncontic pressure)
in the blood affect osmotic pressure, high

lead to edema.
, A drop in blood pressure is sensed by the kidneys

Angiotensin II is also stimulating the adrenal gland
to release aldosterone, which acts to increase
sodium and water reabsorption increasing blood
volume, while also increased potassium secretion
in urine.
