Found Potassium 15 times.

Displaying results 1 to 10.

1. Action potential
A reversal of the electrical potential in the plasma membrane of a neuron that occurs when a nerve cell is stimulated; caused by rapid changes in membrane permeability to sodium and potassium.

2. Acute tubular necrosis (ATN)
This is renal failure characterized by sudden drop in urinary output and the steady increase of serum urea nitrogen and creatinine levels. Common causes of ATN are hypotension, sepsis, burns, and eclampsia. The urine specific gravity is 1.010 or less (loss of ability to concentrate). In the recovery phase, high output failure (low specific gravity, large volume, and lack of ability to excrete nitrogen or potassium) is often the case.

3. Adrenal cortex
This is the outer portion of the adrenal gland ; it secretes hormone s such as hydrocortisone (a glucocortoid) and aldosterone (a mineralocorticoid). Glucocortoids help cells synthesize glucose , catabolize protein s, mobilize free fatty acid s, and inhibit inflammation in allergic responses. Mineralocortoids regulate the levels of minerals such as sodium and potassium in the blood.

4. Aldosterone (aldocortin)
A steroid hormone that is produced by the adrenal cortex and mainly functions to regulate chloride, potassium, and sodium metabolism . Abnormally high levels of this hormone cause symptoms such as sodium retention, high blood pressure, heartbeat irregularities and possibly paralysis.

5. Alkali metal
Any of the highly reactive metals (such as sodium or potassium) found in the first column of the periodic table; these metals act as base s.

6. Channels
Transport proteins that act as gates to control the movement of sodium and potassium ions across the plasma membrane of a nerve cell.

7. Electrolyte
"Electrolyte" refers to ionized salts in the body fluids. The major electrolytes are made from sodium, potassium, magnesium, calcium, chloride, bicarbonate, phosphate and protein.

8. Eosin
* A red, fluorescent , bromine-containing, water-insoluble dye used mainly in toner and cosmetics. * A red or brown potassium or sodium salt of the above dye; it is used as a biological stain and in pharmaceuticals.

9. Hemodialysis
Hemodialysis is performed by extracorporeal circulation of the patient's blood such that the dialysate solution and the blood is separated only by a thin membrane which allows water soluble molecules to exchange. Since the dialysate contains low concentration of many of the toxic metabolite s and potassium , this method effectively lowers the concentration such molecules in blood.

10. Kidneys
Two organs in the lower back that clean waste and poisons from the blood. The kidneys are shaped like two large beans, and they act as the body's filter. They also control the level of some chemicals in the blood such as hydrogen, sodium, potassium, and phosphate.
