po·tas·si·um

 (pə-tăs′ē-əm)
n. Symbol K
A soft, silver-white, extremely reactive element that is an alkali metal, is essential to plant and animal cell functions, and occurs in nature only in compounds. It can be obtained by electrolysis of its hydroxide and is found in, or converted to, a wide variety of salts used especially in fertilizers and soaps. Atomic number 19; atomic weight 39.098; melting point 63.5°C; boiling point 759°C; specific gravity 0.86; valence 1. See Periodic Table.

[From earlier potass, potash (from which it was first obtained), from French potasse, from Dutch potas : pot, pot (from Middle Dutch; akin to Old English pott) + as, ash (from Middle Dutch asche; see as- in Indo-European roots).]

po·tas′sic adj.

potassium

(pəˈtæsɪəm)
n
(Elements & Compounds) a light silvery element of the alkali metal group that is highly reactive and rapidly oxidizes in air; occurs principally in carnallite and sylvite. It is used when alloyed with sodium as a cooling medium in nuclear reactors and its compounds are widely used, esp in fertilizers. Symbol: K; atomic no: 19; atomic wt: 39.0983; valency: 1; relative density: 0.862; melting pt: 63.71°C; boiling pt: 759°C
[C19: New Latin potassa potash]
poˈtassic adj

po•tas•si•um

ISLAMABAD -- Eating foods rich in potassium, such as bananas and avocados, daily may prevent hardening of the arteries that can result in heart disease and death, researchers claim.
Both may prevent hardening and narrowing of the arteries, a condition known as atherosclerosis, because they are rich in potassium, scientists believe.
Researcher Professor Paul Sanders, from the University of Alabama at Birmingham, US, said: "The findings have important translational potential since they demonstrate the benefit of adequate potassium supplementation on prevention of vascular calcification in atherosclerosis-prone mice, and the adverse effect of low potassium intake.
A study in mice found for the first time reducing dietary potassium promoted arterial stiffness, which in humans can lead to heart attacks and strokes.

A banana a day will keep your potassium at a healthy level and will help to keep a normal water balance in your body and prevent high blood pressure.
