NUR 2392 MODULE 3
1. Passive Transport
Filtration
the movement of solute 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 of solvent across a semipermeable membrane from an area of lower solute
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.
5. Angiotensin II
converted from angiotensin I as the blood passes through the lungs. This results in
vasoconstriction to increase blood pressure.
6. Aldosterone
in response to the decrease in blood pressure the adrenal cortex secretes to which results in
sodium and water reabsorption by the kidneys. This increases vascular volume and blood
pressure.
7. Antidiuretic hormone
released by the posterior pituitary gland to regulate the amount of water excreted by the
kidneys. The amount of hormone released is dependent on the blood volume or concentration of
water in the blood.
8. Electrolytes
play a vital role in maintaining homeostasis. The concentration of is controlled by
hormones that are excreted by the kidneys and adrenal glands. Understanding the normal values
