o Increased glucose, tachycardia, dilated pupils, high BP
Homeostasis
o A state of balance among all body systems needed for the body to
survive and
function correctly.
Ribosomes
o Site of protein synthesis
Glucagon
o A hormone that is released to raise your glucose levels.
Endocrine system releases
o Hormones
Causes of edema
o Albumin (plasma protein)
o Increased capillary hydrostatic pressure
o Decreased plasma oncotic pressure
o Increased capillary permeability
o Lymphatic obstruction
Intracellular fluid-contains what?
o Fluid within the cells
o Potassium and phosphate and magnesium
o Constitutes 2/3 total body fluid.
Extracellular fluid-contains what?
o fluid outside the cells
o contains sodium and chloride and carbon.
o constitutes 1/3 total body fluid.
Hyponatremia-leads to what?
o Cerebral edema may occur with severe or acute hyponatremia.
o Water enters the brain and swelling occurs.
Hypovolemia-leads to what?
o Increase in level of blood solutes, cell shrinkage, and hypotension.
Definitions:
o Contraindication – a reason for a person to not receive a particular
treatment or
procedure because it may be harmful.
o Sign – any physical evidence of a disease
o Symptoms – a physical or mental problem a person experiences
that may indicate

Insensible water loss
o The amount of body fluid lost daily that is not easily measured
from the
respiratory system, skin, and water excreted in stool.
o Tachypnea, sweating.
Hypotonic solution
o Lower solute concentrations, causing fluid to shift out.
Isotonic solution
o equal solute concentrations, causes no fluid shifts.
Osmosis
o passive movement of water/solvent across membrane towards
higher
concentrations (osmotic pressure)
o movement between the intracellular and interstitial compartments
o Lysis and crenation
ABGs
o pH: 7.35-7.45
o HCO3: 22-26
o PaO2: 80-100
o PaCO2: 45-35
Diffusion
o Electrolytes moving across the capillary wall.
, o movement of solutes towards lower solute concentrations
Hypernatremia and increased serum osmolality leads to what?
o Fluid shifts
What do the lungs do?
o Move fresh air into your body while removing waste gases.
o Remove carbon and carbonic acids.
