Definition
| Fluid moves in and out of capillaries |
|
|
Term
|
Definition
| Force of fluid pushig out against a surface |
|
|
Term
Blood colliod osmotic pressure
or
oncotic pressure |
|
Definition
| inward pulling force caused by blood proteins that help move fluid from the intersitial are back into capillaries |
|
|
Term
|
Definition
Moves electrolytes across cell membrane againt concetrauion gradient.
NEEDS ATP
ex: sodium postassium pump |
|
|
Term
|
Definition
- Passive movement of electrolytes down a concetration gradient from higher to lower.
|
|
|
Term
|
Definition
- Water moves moves through a membrane that seperates fluids with different particle concentrations.
- passive movement of fluid from an area of lower solute concentration to higher concentrtion
- Osmotic pressure.

|
|
Term
|
Definition
| inward pulling force caused by particles in the fluid |
|
|
Term
|
Definition
| enzyme increases the amount of angiotensinogen in the blood, which eventually increases blood pressure. It increases the release of aldosterone, a hormone that helps control the body's salt and water balance. |
|
|
Term
|
Definition
- Causes resorptionof sodium and water in isotonic porportion in distal rental tubulues
- Sodium and water returns to blood, increaseing ECF volume
- Contributes to electrolyte and acid-base balance by increaseing urinary excretion of postassium and hydrogens ions.
- more renin is released with decreased blood flow to kidneys
|

|
Term
ANP
Atrial natriurertic Peptide |
|
Definition
- Stops ADH by by increasing the loss of sodium and water in urine
- Influences how much sodium and water are excreted in urine.
- Cells in atria of heart release ANP when stretched (increased ECV)
- ANP has opposite of effect as aldosterone

Definition
| what decreases vascular volume? |
|
|
Term
|
Definition
- This is a Extracellular volume deficit and hypernatremia
- EVC is too low and body fluids too concentrated
- Body fluids have decreased volume and hypertonic
