Fluids and Lytes_08
Fluid and lytes
| Question | Answer |
|---|---|
| The most abundant electrolytes in ICF | are:Potassium, Phosphorus, Magnesium |
| Major electrolytes In ECF are? | Sodium Chloride |
| What solution raises serum osmolarity and pulls fluids and electrolytes from interstitial compartments into intravascular compartment? | Hypertonic |
| Isotonic solutions what type of osmolarity? | The osmolarity as serum and other body fluids; no movement occurs |
| what doe Hypotonic sollution cause ? | Causes: fluids and electrolytes to shift out of the intravascular compartment, into the cells and interstitial spaces. |
| what type of transport is sodium potassium pump? | sodium-potassium pump requires the expenditure of energy;therefore it's an example of active transport. |
| Passive transport mechanisms are which types that require energy use? | diffusion osmosis |
| a pH below 7.35 reflects | acidosis or hydrogen ion excess |
| A pH above 7.45 reflects | alkalosis, or hydrogen ion deficit. |
| Osmosis is ? | movement of water through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration |
| Diffusion? | movement of solutes from an area of higher solute concentration to an area of lower solute concentration is diffusion. |
| Filtration? | the movement of water and some solutes by hydrostatic pressure is filtation. |
| Active transport? | the movement of solutes using energy is active transport. |
| Sodiurm is a cation? | sodium is a cation or positively chaged electrolyte |
| What are anions? | Chloride and phosphorus |
| an example of nonelectrolyte ? | Glucose. |
| volume imbalances involve? | sodium and water increasing or decreasing together ways:interstitial fluid volumeintrvascular voluem third space ex ascities, pleural or pericardial effussion |
| ascites | an abnormal accumulation of serous fluid within the peritoneal cavity |
| Effusions | ecape of fluid into part |
| Fluid shifts what ways? | decreased vascular colloid osmotic pressureincreased capillary hydrostatic pressre increased capillary permeabilitylymph obstruction |
| colloid osmotic pressure called oncotic pressure | pressure created by plasma protieings. Pulls flid back into blood vesesels at venous end of the capillary bed,, Also called oncotic pressure. |
| hydrostatic pressure | a pussing pressure at the arterial end of the capillary bed. forces water oxygen and nutrients through capillary walls into interstial spaces. |
| Lymph | body fluid collected from tissure in all parts of the body and returned to the blood via the lymphatic system. found in lymph vessesls. |
| decreased colloid osmotic/oncotic pressure | a decrease in serum protein result in low colloid osmotic pressure as In:malntrtionburns nephrosisliver disease |
| What would be the result of low colloid osmotic (oncotic) pressure? | ess water pulled into the blood vessel from the interstitiial spaces Colloid oncotic pressure puls fluid back into blood vessels at the venous end of the capillary bed. |
| If less water is pulled back into the lood vessel from he interstitial space, total blood volume will: | ecreased More water would rmain in the interstitial spaces, and total blod volume would be lower. |
| Increased venous hydrostatic pressure examples | such:heart failure cirrhoisis Prevents wter from moving fom the intersttial space into the vascular space. |
| hydrostatic pressure is higher at the venous end of the capillary than th colloid oncotic pressure, so water is not pulled back into the vascular bed. | Tissure edema |
