Fluid & electrolyte

Fluid & electrolyte Med-Srug.

Fluid found inside the cells intracellular fluid
Fluid found outside the cell extracellular fluid
ECF is broken down into intersitial and intravascular fluid
positive charge cation
negative charge anion
Na+ range 136-145
K+ range 3.5-5.5
Ca++ range 8.5-10.5
Mg++ range 1.6-2.6
PO4-- range 3.0-4.5
Cl- range 98-106
HCO3- has a ratio of 1 part carbonic acid to hoe many parts of HCO3? 20
Main ICF cation K+
Regulates cell excitability K+
Permeates cell membranes and affects the cells electrical status K+
helps to control ICF osmolality & consequently ICF osmotic pressure K+
A leading ICF cation Mg++
contributes to many enzymatic & metabolic processes, particularly protein synthesis Mg++
modifies nerve impulse transmission & skeletal muscle reponse Mg++
main ICF anion PO4--
promotes energy storage & carbohydrate, protein, & fat metabolism PO4--
acts as a hydrogen buffer PO4--
main ECF cation Na+
helps govern normal ECF osmolality Na+
helps maitain acid base balance Na+
activates nerve and muscle cells Na+
Influences water distribution Na+
main ECF anion Cl-
helps maintain normal ECF osmolality Cl-
affects body pH Cl-
plays a vital role in maintaining acid base balance; combines w/hydrogen ions to produce hydrochloric acid Cl-
a major cation in teeth and bones; found in fairly = concentrations in ICF and ECF Ca++
found in cell membranes, where it helps cells adhere to one another and maintain their shape Ca++
acts as an enzyme activatior with in cells Ca++
aids in coagulation Ca++
affects cell membrane permeability and firing level Ca++
found in both organic and inorganic compounds, is necessary in metabolizing glucose and other chemical compounds into energy Oxygen
found in all organic compounds; necessary for cellular respiration Carbon
involved in pH; component of water; necessary for life Hydrogen
important in proteins, an energy source; and a compoonent of hormones Nitrogen
important in boneandteeth composition; involved in nerve conduction, muscle contraction, and blood clotting. Calcium
found in bones, teeth, the high energy carrying compound adenosine triphosphatase, some protiens, andnucleic acid. Phosphorus
major electrolyte in ICF important in muscle contraction and transmission of nerve impulses; activates enzymes; influences cellulsr osmotic pressure; invovled in kidney function and acidbase balance. Potassium
found in some proteins, nucleic acids, and some vitamins and hormones Sulfur
major electrolye in ECF; important in osmoregulation and acid base balance; necesssary for nerve transmission and muscle contraction Sodium
found in ECF; important in water balance, acid base balance and production of hydrochloric acidin the stomach chlorine
important in muscle and nerve function and bone formation and in some coenzymes Magnesium
important component of vitamin B12 Cobalt
necessary for formation of HgB and for bone development Copper
a cofactor involved with enzymes for fat, cholesteral, and glucose. Chromium
Gives hardness to teeth and bones Fluorine
necessary for synthesis of thyroid hormone Iodine
necessary for transportation of oxygen by HgB Iron
necessary in activating some enzymes Manganese
acts with vit. E as an antioxidant; component of teeth Selenium
found in some enzymes; needed for protein metabolism and carbon dioxide transport Zinc
Oxygen, hydrogen, nitrgen, and carbon make up how much of the total body weight of the elements 95%
Embryo body water 97%
infant body water 70%-80%
child body water 60%-77%
adult body water 60%
Older adult body water 45%-55%
Human life is suspended in a saline solution having a salt concentration of? 0.9%
released by the posterior pituitary gland; acts on the distal tubules of the kidneys to reabsorb water ADH
produced in the adrenal cortex; causes the reabsorption of sodium from the renal tubules, leading to water retention in the ECF, increaseing its volume. Aldosterone
released by the juxtaglomerular cells of the kidneys promotes vasoconstriction and the release of aldosterone Renin
oral liquid intake / day 1300 mL
water in food intake / day 1000 mL
