Acidosis - Alkalosis

An excess in acidity in the blood and other body fluids is called acidosis while excess in alkalinity is called alkalosis. The normal pH of the blood is 7.4 and acidosis occurs when the pH falls below 7.35 and will be called severe acidosis when the reading falls below 7.0. Alkalosis occurs when the pH rise above 7.45 and will be called severe alkalosis when reaches above 7.5.

Acidosis and Alkalosis are both symptoms of various diseases and disorders.





Calcium - Phosphorus


The functions of phosphorus in the body are the following: building and repair bones and teeth, help nerves function, and for muscle contraction.
Almost 85% of the phosphorus contained in phosphate is found in bones. The rest of it is stored in tissues throughout the body.

Calcium functions in the body are: catalyst for nerve transmission and conduction, muscle contraction, promotes coagulation of blood.

Calcium and phosphate in the body react in opposite ways: As blood calcium levels rise, phosphate levels fall. Diseases or infection may disrupt this relationship that is why phosphate and calcium levels are usually measured at the same time.

Hyperkalemia

Hyperkalemia means an abnormal high level of potassium in the blood. This condition is a medical emergency since it can cause cardiac arrest. Some management are: insulin (to increase cellular reuptake); a gluconate (antagonize cardiac effect); Na bicarbonate (reverse acidosis); kayexalate (K exchange resin); dialysis; and diuretics.
