Blood clumping, also known as agglutination, occurs when different blood types are mixed. This may prove fatal when it occurs inside the body.Know More
In humans, the blood is an essential component that functions in the transportation of vital substances to and from the body, regulation of internal mechanisms and defense against foreign particles that invade the body. The primary constituents of blood include plasma, red blood cells, white blood cells and platelets.
In 1901, the Austrian scientist Karl Landsteiner identified the ABO blood group. This discovery vastly improved the success of medical blood transfusions. The ABO blood group comprises four blood types: A, B, AB and O. Each blood type is determined by the presence or absence of antigens and antibodies. Antibodies are found in the blood plasma while antigens are attached to the surface of the red blood cells. When different blood types are combined, the antigens from one type bind to the antibodies of the other type, which results to clumping or agglutination. The clumped blood may constrict the blood vessels and prevent the proper circulation of blood. Agglutination may also trigger the red blood cells to rupture and spill their hemoglobin content, which becomes poisonous once outside the cell and may even cause the death of the individual.Learn more about Blood

People whose blood is too thin are prone to excessive bleeding that is potentially dangerous. Those with thin blood lack sufficient platelets, which are cell fragments that help the blood form clots. Health Guidance reports these people tend to experience nose bleeds, bleeding gums, frequent bruising all over their bodies and even blood in their urine.Full Answer >
When blood is too thick, it clots more easily, and the potential exists for blockage of the blood flow through the arteries and veins, according to the National Heart, Lung and Blood Institute. This may trigger a heart attack or stroke. Polycythemia vera is a condition in which the body produces too many red blood cells, causing thickening of the blood and increasing the possibility that clotting occurs.Full Answer >
Receiving the wrong blood type can lead to a severe reaction that is potentially life threatening, according to WebMD. Symptoms such as fever, hives, shortness of breath, chills, low blood pressure and pain are all reactions that can range from mild to severe that are linked to blood transfusions. This is a rare occurrence caused by human error that happens in just one out of every 14,000 transfusions performed.Full Answer >
