|---|---|---|---|---|---|
| electrolytes | compounds which dissociate in solution to form ions
🗑
|
||||
| non-electrolytes | molecules that remain intact in body water e.g. glucose, BUN, creatinine
🗑
|
||||
| renin-angiotensin-aldosterone | system which aids in regulation of blood volume
🗑
|
||||
| renin | enzyme from kidney, converts angiotensinogen to angiotensin I
🗑
|
||||
| angiotensin II | 3 functions - vasoconstriction, acts on hypothalamus to initiate ADH secretion, acts on adrenals to secrete aldosterone
🗑
|
||||
| aldosterone | adrenal hormone which acts on kidney to retain sodium (& water) and excrete potassium
🗑
|
||||
| natriuretic peptides | ANP, BNP hormones which promote sodium (and water) excretion from the kidney
🗑
|
||||
| osmolality | physical property of a solution based on the concentration of solutes per kilogram of solvent
🗑
|
||||
| colligative properties | describes the behavior of solutions that can change based solely on the concentration of particles present
🗑
|
||||
| ADH-thirst sensation | regulatory mechanisms of the hypothalamus stimulated by plasma osmolality
🗑
|
||||
| bone minerals | calcium, phosphorus, magnesium
🗑
|
||||
| lactate | by-product of anaerobic metabolism
🗑
|
||||
| anion gap | estimation of the difference between the unmeasured anions and unmeasured cations
🗑
|
||||
| ionized calcium | physiologically active form of calcium
🗑
|
||||
| total calcium | total of all forms of calcium in plasma (protein-bound, anion-bound, free)
🗑
|
||||
| sodium | major extracellular cation
🗑
|
||||
| potassium | major intracellular cation
🗑
|
||||
| chloride | major extracellular anion
🗑
|
||||
| bicarbonate | extracellular anion
🗑
|
||||
| ISE | ion selective electrode - measures the voltage (potential) differences between the measuring electrode and the reference electrode
🗑
|
||||
| mmol/L | units for electrolyte measurements
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
