body fluid chemistry

The pericardium or around the heart is known as pericardial fluid. The tonicity of body fluids is reflected by the serum sodium concentration which is a function of the bodys content of sodium and potassium more precisely the portion that is free in solution and not bound to proteoglycans in bone cartilage and connective tissue divided by its content of waterSerumsodiumconcentrationTotalbodyNaKTotalbodywater.

Interestingly the ionic composition of plasma is.

. COMPOSITION OF BODY FLUIDS INORGANIC SUBSTANCES. The cerebral spinal fluid CSF is a clear bodily fluid that occupies the space between the arachnoid mater meninges and the pia mater. Most body fluids are neutral in charge.

It all comes down to differences in chemical structure and conjugation. Total body water is divided into three fluid compartments. We can compute the concentration of any solution using the following equation.

Humans are approximately 75 water by mass as infants and 50 to 60 water by mass as adults. Any fluid in the body including blood urine saliva sputum tears semen milk or vaginal secretions. The blood transports nutrients wastes and gases throughout the body.

They are not derived from blood or urine and include cerebrospinal fluid CSF serous fluids pleural peritoneal and pericardial synovial fluid and drainage and dialysis fluids among others. The fluid is formed predominantly at the choroid plexus deep within the brain and by the ependymal cells lining the ventricles. Blood comprises plasma white blood cells red blood cells and platelets.

It is the essence of life and the aqueous base solution in which all essential biochemical processes occur that produce life. Electrolyte concentrations of body fluids are usually expressed in milliequivalents per liter mEqL a measure of the number of electrical charges in one liter of solution. Individual registration codes as followed.

The methods to measure these substances are carefully designed to provide accurate assessments of their concentration. MEqL ion concentration mgL divided by the atomic weight of the ion mgmmol X the number of. Laboratory testing can be performed on many types of fluids from the body other than blood.

Blood and lymph are the two main body fluids in the human body. Hussong JW and Kjeldsberg CR Eds. The CSF is involved in the distribution of hypophyseal hormones within the brain and the clearance of hormones from the brain to the blood.

2 extravascular interstitial fluid or lymph. Bile The red blood cells. And 3 intracellular fluid fluid inside cells.

Human beings are creatures that are primarily composed of water. It constitutes the content of all intra-cerebral ventricles cisterns and sulci as well as the central canal of the spinal cord. However understanding the clinical utility of these analytes is critical because laboratories must address the analytic and clinical validation requirements while educating clinicians on.

Chloride Cl Glucose Lactate Dehydrogenase LDH Lipase Potassium K Protein Total Rheumatoid Factor RF Sodium Na Triglycerides Uric Acid Suggested References Additional Resources and Clinical Information Kjeldsbergs Body Fluid Analysis. Fetal Fibronectin fFN Amniotic Fluid Analysis. Basic knowledge on different types of body fluids are crucial as these fluids are part of the vehicles that involve in the causes and manifestation of life threatening-diseases such as heart failure and cancers.

Thus cations or positively charged ions and anions or negatively charged ions are balanced in fluids. This also has a role to play in the colours of other bodily fluids and the haem structures in blood are the point of origin for all of them. Body Fluid Chemistry Return Test Information Test Name.

Intracellular fluid contains large quantities of potassium magnesium phosphates sulphates and proteins. Furthermore fluid is always in flux through a variety of regulatory mechanisms. Often these fluids are tested instead of blood because they can give more direct answers to what may be going on in a particular part of the body.

Body fluid testing for a number of analytes has been reported in the literature. It is formed in the choroid plexus by both filtration and active transport. Extracellular fluid contains large quantity of sodium chlorides bicarbonate glucose fatty acids and oxygen.

PH of ECF is 74 PH of ICF is 7 12. Clinical chemistry is a quantitative science that is concerned with measurement of amounts of biologically important substances called analytes in body fluids. There are many types of body fluids including cerebrospinal fluid pleural fluid pericardial fluid peritoneal or ascitic fluid amniotic fluid synovial fluid and saliva.

For most of the body fluids biochemistry analysis it is recommended to run paired samples fluid together with blood samples in order to confirm the diagnosis of diseases. Body fluids defined as specimens other than plasma serum or urine include cerebrospinal fluid CSF dialysate postsurgical drain fluid wound fluid and other fluids often obtained using. Group code FLUI consists of Fluid ProteinGlucoseAmylase.

The cerebrospinal fluid is a clear body fluid that occupies the space between the. The pathological accumulation of these body fluids occurs due either to increased production or reduced rate of absorption. The total CSF volume is about 150 mL or about 8 of the total CNS cavity volume.

Some body fluids that may be tested include. As seen in the previous graph sodium Na ions and chloride Cl ions are concentrated in the ECF of the body whereas potassium K ions are concentrated inside cells. BF is often used with specific reference to those fluids to which health care workers might reasonably be exposed including blood urine saliva and semen.

The peritoneum or around the abdominal cavity is known as. Plasma is also made of 1 ions or salts mostly sodium chloride and bicarbonate. The pleura or around the lung is known as pleural fluid.

90758 SummaryBody Fluids from a Geochemical Perspective. As summarized in Table 4 and Figures 47 various human body fluids with which Earth materials may come into contact exhibit a wide range of compositions including their pH and Eh electrolyte content and concentrations of organic species such as amino acids organic acids and proteins. FLAM Fluid Amylase.
