Fluid Balance
Fluid and Electrolyte balance
| Question | Answer |
|---|---|
| Water moves toward higher region? | Osmotic pressure |
| Renin-angiotensin-aldosterone | Maintains normal blood volume at expense of IF Volume. |
| Intake must = ... | Output |
| How does water leave the body? | Breath, Urine, Feces, Skin |
| How does water enter the body? | Intake (Swallow)and Cell Metabolism. |
| Chemical Structure of Plasma, IF and ICF helps ______ and _______ create homeostasis. | Water and Electrolytes. |
| Primary Mechanics (6) | Vomiting, diarrhea, Low BP, Sweating, Hyper Ventilation, Renin released. |
| Hydrostatic Pressure | Forces fluid out of IF into the capillaries (Starling Law) |
| Blood Colloid Osmotic Pressure | Draws blood from IF to capillaries. (starling Law) |
| Blood Hydrostatic Pressure | Forces fluid out of capillaries into IF. |
| Starlings Law of Capillaries | The physical laws of filtration and osmosis control mechanisms for water exchange between plasma. |
