1. Passive Transport
Filtration
themovement ofsolute through a capillary mem- brane due to hydrostatic pressure. Fluid moves
from an area of higher pressure to an area of lower pressure. Movement of fluid continues until
the hydrostatic pressure is equal resulting in fluid balance or equilibrium.
2. Passive Transport
Diffusion
the movement of solvent across a biological membrane (permeable, semi-permeable and
impermeable) from an area of higher particle concentration to an area of lower particle
concentration.
3. PassiveTransport
Osmosis
the movement ofsolvent across a semipermeable membrane froman area oflowersolute
concentration to one of higher concentration.
4. Renin-Angiotensin-Aldosterone
renin is excreted by the kidneys in response to a decrease in blood pressure, blood volume, low
sodium, and low blood oxygenation. The secretion of renin causes angiotensinogen to be
broken down to form angiotensin I.
