intracellular fluid is
45% body weight 75% body water
extracellular fluid is
15% body weight 25% body water
pathology
study of disease and its causes
pathophysiology
study of how diseases alter normal physiology
atrophy
the process of decraesing size and increasing effeciency
hypertrophy
increase in the size of the cell and its functional mass including an increase in the number of organelles
hyperplasia
an increase in the number of cells due to an increase in workload
metaplasia
replacement of one type of cell by another type of cell that is not normal for that issue
intravascular fluid is
4.5% body weight 7.5% body water
dysplasia
change in a cells size, shape or appearance caused by an external stressor
what % of body weight is water
0.6
interstitial
10.5% body weight 17.5% body water
hypoxia
oxygen deficiency
ischemia
blockage or reduction of delivery of oxygenated blood to the cells
anabolism
constructive phase of metabolism
catabolism
destructive phase of metabolism
what are the formed elements of blood
erythrocytes-redblood cells leukocytes-white blood cells thrombocytes-platelets
colloids
substances such as protiens or starches consisting of large molecules or molecule aggregates that disperse evenly within a liquid without forming a true sulution
albumin
a protein in the blood that works to maintain blood volume and pressure which prevents plasma loss from the capillaries
crystalloids
substances capable of crystallization. in solution, unlike colloids, they can diffuse through a membrane, such as a capillary wall
sodium
most abundant extracellular cation
tonicity
solute concentrationor osmotic pressure relative to the blood plasma or body cells
respiratory acidosis
acidity caused by abnormal retention of carbon dioxide resulting from impaired vilation
respiratory alkalosis
alkalinity caused by excessive elimination of carbon dioxide resulting from increased respirations
potassium
most abundant intercellular cation
what are the mechanisms that maintain hydration
pituatory gland, salivary flow, kidneys, shifts between spaces, increase thirst
metabolic acidosis
acidity caused by an increased in acid often because of increased production of acids durring metabolism or from causes such as vomiting , diarreah, diabetes, or medacation
what are the s/s of dehydration
decreased skin turgor increased thirst increased pulse decreased pulse dry skin and membranes
calcium
extracellular cation, blood coagulation, muscle contraction, neuromuscular transmission-depolarization
metabolic alkalosis
alkalinity caused by an increase in plasma bicarbonate resulting from causes including diuresis, vomiting, or injestion of too much sodium bicarbonate
chloride
extracellular, follows sodium, role on kidney function
normal ph
7.35 - 7.45
bicarbonate
extracellular, weak base, buffer, 20 bicarbonate ions to evry 1 carbonic acid
normal pao2
80 - 100 torr
normal hco3
22 +/- 4 meq
phosphate
intracellular, structural component of bone/teeth, role in renal function
normal sao2
97 - 100 torr
isotonic solution
tonicity similar to blood, no fluid or electrolyte shift, lactated ringers, normal saline
hypertonic solution
solute tonicity higher than cells, fluid in/solutes out, d50w, hco3(bicarb), manitol
hypertinic solution
solute tonicity lower than cells, fluid in/solutes out, d5w
edema
accumulation of water in the interstitial space, decreased in plasma oncotic force, increase in hydrostatic pressure, increased capillary permiability, lymphatic chanel
