Homeostasis - •state of equilibrium or balance within and organism
•Fluids and electrolytes exist within the body, are dynamic in nature, and are
maintained in constant balance, or homeostasis, within the body
fluid volume deficit - •Fluid deficit occurs when total body fluid levels (mostly
water) are insufficient to meet the body's needs may also be referred to as
dehydration
•Fluid volume deficits may result from vomiting and diarrhea
Fluid Volume Excess - •Daily fluid intake should equal the amount of fluid lost
•Third spacing: significant fluid increases in the transcellular compartment, which
does not exchange easily among other ECFs
Types: Edema, Water intoxication
Eukaryote - •is any cell or organism that possesses a defined nucleus
Mitochondria - •Have own DNA and ribosomes
•Produces adenosine triphosphate (ATP) for energy
what happens When arterial blood pressure decreases - •renin is released from the
kidneys and works on angiotensinogen (from the liver), converting it to
angiotensin I.

What is the role of renin-angiotensin-aldosterone system, antidiuretic hormone
(ADH), and natriuretic peptides - Control of fluid and electrolyte balances is
maintained
The renin-angiotensin-aldosterone system (RAAS) also assist in - •maintaining
blood pressure and intravascular fluid status
What happens when renin converts angiotensinogen (from the liver), converting
into angiotensin I - •Angiotensin I is then converted to angiotensin II in the lungs
by angiotensin-converting enzymes
what is the role of Angiotensin II - •is a potent vasoconstrictor that also stimulates
the release of aldosterone
What produces Aldosterone - Hyopthalamus
What releases Aldosterone and why - The adrenal cortex releases and releases in
response to changes in blood osmolality
What is the role of Aldosterone - promotes the retention of the sodium and water in
the kidneys, restoring blood volume
directly influences water reabsorption in the distal tubules and collecting ducts in
the kidneys
What may cause Fluid volume deficient - •hemorrhage, excessive loss of GI fluids
(e.g., vomiting, diarrhea).

What are the symptoms of Fluid volume deficient - thirst, weight loss, lungs clear
to auscultation, tachycardic.
What may cause fluid volume excess - •heart failure, end-stage kidney failure, etc.
What are the symptoms of Fluid volume excess (FVE) - •crackles in the lungs,
hypertension, bounding pulses.
Where is the highest loss of daily fluids - in the urinary tract
Osmosis - •process which water travels through a selectively permeable membrane
so the concentrations of a substance that is soluble in water (solutes) are the same
on both sides of the membrane. (ex. movement of water between the interstitial and
intracellular compartments).
what type of movement is osmosis - Through osmosis water passively moves from
an area of lower particle concentration to an area of higher particle concentration.
Where does Potassium mostly exist in the body - •exists predominately in the
intracellular fluid whereas sodium and chloride exists predominately in
extracellular fluid.
hypokalemia - When potassium levels in the body is less than 3.5 mEq/L
hyperkalemia - When potassium levels in the body is greater than 5 mEq/L
Both hypokalemia and hyperkalemia can cause - cardiac arrhythmias
