It’s contained in the body as phosphate. (The two words—p Ebook Fluids and electrolytes made incredibly easy (6/E): Part 2hosphorus and phosphate—are commonly used interchangeably.) About 85% of phosphorus exists in bone and teeth, combined in a 1:2 ratio with calcium. AbEbook Fluids and electrolytes made incredibly easy (6/E): Part 2

Phosphorus is a primary ingredient in 2,3-diphosphoglycerate (2,3-DPG), a compound in red blood cells (RBCs) that promotes oxyg Ebook Fluids and electrolytes made incredibly easy (6/E): Part 2en delivery from RBCs to the tissues.Phosphorus also helps buffer acids and bases.

y-storing substances such as adenosine triphosphate (ATP). It’s also important for white blood cell (WBC) pliagocytosis and for platelet function.

In comparison, die normal phosphorus level in the cells is 100 mEq/L. Because phosphorus is located primarily within the cells, serum levels may not always reflect the total amount of phosphorus in the body. For example, it’s important to distinguish Ebook Fluids and electrolytes made incredibly easy (6/E): Part 2 between a decrease in the level of serum phosphate (hypophosphatemia) and a decrease in total body storage of phosphate (phosphate deficiency).How thEbook Fluids and electrolytes made incredibly easy (6/E): Part 2

(See PTII and phosphorus.) Changes in calcium levels, rather than changes in phosphorus levels, affect the release of P i H. You may recall that phos Ebook Fluids and electrolytes made incredibly easy (6/E): Part 2phorus balance is closely related to calcium balance.Chapter 9When phosphorus tips the balanceJust the factsIn this chapter, you’ll learn:♦the role that phosphorus plays in the body♦the body’s mechanismsChapter 9When phosphorus tips the balanceJust the factsIn this chapter, you’ll learn:♦the role that phosphorus plays in the body♦the body’s mechanismsGọi ngay
