An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
[3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3] Its anticoagulant properties make it useful to prevent blood clotting in blood specimen test tubes and kidney dialysis ...
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but which contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. [1] It is the intravascular part of extracellular fluid (all body fluid outside cells).
Protein C is a major physiological anticoagulant. It is a vitamin K-dependent serine protease enzyme that is activated by thrombin into activated protein C (APC). Protein C is activated in a sequence that starts with Protein C and thrombin binding to a cell surface protein thrombomodulin. Thrombomodulin binds these proteins in such a way that ...
Blood accounts for 7% of the human body weight, [9] [10] with an average density around 1060 kg/m 3, very close to pure water's density of 1000 kg/m 3. [11] The average adult has a blood volume of roughly 5 litres (11 US pt) or 1.3 gallons, [ 10 ] which is composed of plasma and formed elements .
Human blood after separation by centrifugation. Plasma (upper layer), buffy coat (middle, white-colored layer) and erythrocyte (red blood cell) layer (bottom) can be seen. The buffy coat is commonly used for DNA extraction, [ 4 ] with leukocytes providing approximately 10 times more concentrated sources of nucleated cells. [ 5 ]
Acid-citrate-dextrose or acid-citrate-dextrose solution, also known as anticoagulant-citrate-dextrose or anticoagulant-citrate-dextrose solution (and often styled without the hyphens between the coordinate terms, thus acid citrate dextrose or ACD) is any solution of citric acid, sodium citrate, and dextrose in water.
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
