UI	MeSH Term	Description	Entries
D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D005936	Glucans	Polysaccharides composed of repeating glucose units. They can consist of branched or unbranched chains in any linkages.	Glucan,Polyglucose,Polyglucoses,Glucan (BO),Glucose Polymer,Polycose,Polymer, Glucose
D006321	Heart	The hollow, muscular organ that maintains the circulation of the blood.	Hearts
D006327	Heart Block	Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
