Nutrition and Metabolism - Essay Examplethe plasma sodium concentration), is about one hundred forty mmol/L. Sodium maintains the osmotic pressure of the extra cellular fluid and helps in retaining water in the extra cellular compartment. Along with other cations it is also majorly twisty in neuromuscular irritability, acid base balance, maintenance of blood viscosity and resting membrane potential.A high plasma sodium concentration (more than 145 mmol/L) is referred to as hypernatremia. This can occur out-of-pocket to simple dehydration, excess sodium intake, steroid therapy and diabetic insipidus. Hyponatremia (plasma sodium concentration less than 130 mmol/L), can occur due to diuretic medication, kidney disease, excessive sweating, congestive heart failure or gastrointestinal disorder.chiliad is one of the most important intracellular cation. It is widely distributed in the be in muscle tissue, nerve tissue, blood cells and plasma. It is filtered in the glomerulus, absorbed in the proximal tubule and finally excreted by exchange for sodium in the distal tubule. Potassium influences muscular activity, cardiac function and nerve conduction process.In hyperkalemia the plasma jet concentration exceeds 5.5 mmol/L. Acute hyperkalemia is a medical emergency. In hypokalemia the plasma potassium level will be less than 3.5 mmol/L. This can occur due to excessive loss in gastrointestinal secretions and urine, and also in renal tubular acidosis.Hyponatremia (lowered plasma Na+) and hypernatremia (raised plasma Na+) are associated with a variety of diseases and illnesses and the accurate measurement of Na+ in body fluids is an important diagnostic aid.Potassium is the major intracellular cation. The modal(a) cell has 140 mM K+ inside but only about 10 mM Na+. K+ slowly diffuses out of cells so a membrane pump (the Na+/K+-ATPase) continually transports K+ into cells against a concentration gradient. The human body requires about 50-150 mmol/day.Hypokalemia (lowered
