Introduction Blood platelets, or thrombocytes, are cells in the blood that play an important role in blood clotting, i.e. stopping bleeding. Along with red blood cells and immune cells (leukocytes), they are one of the main components of the blood. The technical term thrombocyte for blood platelets is derived from the Greek von thrombos for … Platelets
Blood platelet count too high If the platelets in the blood are elevated (>500. 000/μl), this is called thrombocytosis. These can be either primary (congenital, genetic) or secondary (acquired, caused by another disease). Secondary thrombocytosis is usually caused by infections, chronic inflammatory diseases, tissue injuries or certain forms of anaemia. Infections in which elevated platelet … Blood platelet count too high | Platelets
Therapy of platelet diseases A thrombocyte deficiency of less than 50,000 platelets per microlitre of blood is dangerous in most cases and should be treated. Depending on the cause of the deficiency, a number of treatment methods are available. In cases of pure platelet loss after heavy bleeding, for example after a traffic accident, platelet … Therapy of platelet diseases | Platelets
Platelet donation The donation of blood platelets (thrombocyte donation) is a procedure similar to plasma donation, in which 5 to 6 times more thrombocytes can be obtained than in a normal blood donation. In the donation process, only the platelets are removed from the donor’s blood via a “cell separator” and the remaining blood components … Platelet donation | Platelets

Manufacturer Boeringer Ingelheim Application areas Aggrenox® is used to prevent further strokes in patients who have already suffered a stroke. Mode of operation … Aggrenox®
Influence of medication on blood coagulation Blood clotting can be influenced by various drugs. First of all, there are two large groups of drugs that are used specifically to influence coagulation. On the one hand there are anticoagulant drugs. They are also called anticoagulants. These include vitamin K antagonists (Marcumar®), aspirin and heparins. They delay … Influence of medication on blood coagulation | Blood Coagulation
Introduction Blood is responsible in our body for, among other things, the exchange and transport of oxygen, the supply of nutrients to the tissues and organs and the transfer of heat. It circulates constantly through the body. Since it is liquid, there must be a way to stop the blood flow at the site of … Blood Coagulation
Blood coagulation disorders Like every system in our body, the coagulation system can also have various disorders. Since coagulation depends on many factors and substances in the tissue or blood, it is particularly important that no irregularities occur. At the same time, this makes the coagulation cascade very susceptible to errors. Depending on which factor … Blood coagulation disorders | Blood Coagulation
Introduction Every person has about 4-6 litres of blood flowing through his veins. This corresponds to about 8% of the body weight. The blood consists of different proportions, which all take on different tasks in the body. For example, the components play an important role in the transport of nutrients and oxygen, but also for … Functions of the blood
Tasks of the white blood cells The white blood cells (leukocytes) serve the immune defence. They are important in the defence against pathogens and also in the development of allergies and autoimmune diseases. There are many subgroups of leukocytes. The first subgroup is the neutrophilic granulocytes with about 60%. They are able to recognize and … Tasks of the white blood cells | Functions of the blood
Tasks of the electrolytes Various electrolytes are dissolved in the blood. One of them is sodium. Sodium is much more concentrated in the extracellular space, which includes the blood plasma, than within the body cells. It is this difference in concentration that makes special signal transmissions in the cell possible. Sodium is also important for … Tasks of the electrolytes | Functions of the blood
Blood formation Hematopoiesis, also known as haematopoiesis, refers to the formation of blood cells from haematopoietic stem cells. This is necessary because the blood cells have a limited life span. Thus erythrocytes live for up to 120 days and thrombocytes for up to 10 days, after which renewal is necessary. The 1st place of blood … Blood formation | Functions of the blood
