avoiding blood clots

The damaged platelets release a substance called thromboplastin. This sets in action, a series of reactions that result in the formation of clots. These clots block the site of the injury, avoiding excess loss of blood..

Excessive loss of blood is prevented from the cut blood vessels by the formation of clots. This process is also called coagulation. The steps involved in clotting of blood are: Damaged platelets secrete thromboplastin or thrombokinase . Thrombokinas..

The blood contains platelets that secrete substances called the thromboplastin on being damaged. This substance initiates reactions that result in the formation of blood clots. The blood clots prevent excessive flow of blood..

These are colourless, oval shaped and discoidal cytoplasmic fragments formed from the giant cells called megakaryocytes of bone marrow. The average life span of platelets is about 5-9 days. These play a major role in the process of blood clotting . At the site of injury, the pla..

It is caused by the deficiency of vitamin K. Vitamin K is necessary for clotting of blood. Thus in the absence of vitamin K there is delayed blood clotting that leads to profuse bleedin..

The deficiency of this vitamin effects blood clotting mechanism. The blood clotting time increases and the individual bleeds heavily even for minor injuries. Deficiency of vitamin K leads to lack of prothrombin. Excess administration of vitamin K causes jaun..

Endothelium is the inner wall of the blood vessels. The platelets stick to the damaged portion of the endothelium and prevent loss of blood. The platelets are not allowed to stick to healthy endothelium by the secretion of a substance called prostacyclin. Thrombosis is a condit..
