Often expressed in cm/s. This value is inversely related to the total cross-sectional area of the blood vessel and also differs per cross-section, because in normal condition the blood flow has laminar characteristics. For this reason, the blood flow velocity is the fastest in the middle of the vessel and slowest at the vessel wall.
A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.
Hyponatremia. Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. [4] It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. [3][8] Symptoms can be absent, mild or severe. [2][9] Mild symptoms include a decreased ability to think, headaches ...
A higher fluid flow rate in the TAL allows less time for dilution of the tubular fluid so that MD chloride concentration increases. [5] Glomerular flow is decreased if the chloride concentration is above the target value. Constricting the smooth muscle cells in the afferent arteriole, results in a reduced concentration of chloride at the MD.
v. t. e. Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry ...
Hemorheology, also spelled haemorheology (haemo from Greek ‘αἷμα, haima ' blood '; and rheology, from Greek ῥέω rhéō, ' flow ' and -λoγία, -logia 'study of'), or blood rheology, is the study of flow properties of blood and its elements of plasma and cells. Proper tissue perfusion can occur only when blood's rheological ...
In cell biology, extracellular fluid (ECF) denotes all body fluid outside the cells of any multicellular organism. Total body water in healthy adults is about 50–60% (range 45 to 75%) of total body weight; [1] women and the obese typically have a lower percentage than lean men. [2] Extracellular fluid makes up about one-third of body fluid ...
Electrolyte imbalance, or water-electrolyte imbalance, is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological function, fluid balance , oxygen delivery , acid–base balance and much more.
