Unit 5 Vocab

the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy. Active transport
caused when different ions cross the neuron membrane. A stimulus first causes sodium channels to open. Because there are many more sodium ions on the outside, and the inside of the neuron is negative relative to the outside, sodium ions rush into the neur action potential
hormone that helps your kidneys manage the amount of water in your body. released from pituitary gland based on signals from hypothalamus; take in water ADH antidiuretic
Detects the water levels of blood hypothalamus
causes sodium conservation and water retention and excretes potassium; produced in adrenal gland Aldosterone
negatively charged ion anion
positively charged ion cation
a receptor sensitive to changes in pressure baroreceptors
a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. does not diffuse easily calloid
pull water into the circulatory system. calloid osmotic pressure
process that out body makes during shock, these are short term, long term and last term compensatory mechanisms
spreading evenly; high to low concentration diffusion
is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution osmosis
compounds that separate into ions when in a solution electrolyte
outside the cell extracellular
passage of a solution through a semipermeable membrane from high to low filtration
excreting more that what you take in fluid volume deficit
decreased blood volume, more specifically plasma Hypovolemia
too much fluid in the blood fluid volume excess
the net driving force which pushes fluid into tissue spaces and out of vascular sites filtration pressure
greater concentration than body fluids hypertonic
lower concentration than body fluids hypotonic
water that passes through the skin and is lost by evaporation insensible fluid loss
between the cells interstitial
fluid inside the cells intracellular
osmotic concentration equal to the fluid of the body isotonic
occurs when the body produces excessive quantities of acid or when the kidneys are not removing enough acid from the body metabolic acidosis
When the PH in your body gets to low Acidosis
unit used to give concentration of an electrolyte solution milliequivalent
a hormone system that regulates blood pressure and fluid balance RAA system
a condition that occurs when the lungs can't remove enough of the carbon dioxide (CO2) produced by the body respiratory acidosis
it can be seen, felt, and measured sensible fluid loss
It is the most abundant protein in human blood plasm serum albumin
The process of moving sodium and potassium ions across the cell membrane sodium potassium pump
occurs when too much fluid moves from the intravascular space (blood vessels) into the interstitial or "third" space-the nonfunctional area between cells third spacing
the resistance that must be overcome to push blood through the circulatory system and create flow vascular resistance

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
