Clotting begins when a?
blood vessel is torn.
What are platelets and what do they have to with heart problem?
Platelets are a component of blood which are involved in blood clotting which stops bleeding and stops infection. However, if clotting occurs during the normal circulation of the blood, the clot might lodge in some blood vessel, cutting of the blood supply to vital organs, such as the heart.
What is the final result of the clotting process?
Blood clotting is also known as coagulation. On average, it occurs within 3 to 6 minutes of a blood vessel being damaged. There are two main ways for blood clotting to occur: the intrinsic pathway, and the rapid extrinsic pathway. Whichever pathway occurs the final result is always that blood plasma turns into a gel as a result of being combined with fibrin, and this forms a blood clot.
Why does blood clot in a wound but not while flowing through blood vessels?
Coagulation begins almost instantly after an injury to the blood vessel has damaged the endothelium (lining of the vessel). Exposure of the blood to proteins such as tissue factor initiates changes to blood platelets and the plasma protein fibrinogen, a clotting factor. Platelets immediately form a plug at the site of injury; this is called primary hemostasis. Secondary hemostasis occurs simultaneously: Proteins in the blood plasma, called coagulation factors or clotting factors, respond in a complex cascade to form fibrin strands, which strengthen the platelet plug
Blood cell required for the clotting process?
The healing effect of blood clotting of surface wounds comes as a result of blood chemistry and its solids. The solids themselves are cell fragments known as platelets. The clotting action is aided by plasma clotting factors.
What helps seal a cut in a blood vessel?
Handy dandy PLATELETS :p Scientifically called Thrombocytes.
Which is best suited to the clotting process that occurs when blood vessels are ruptured?
Platelets
A stroke occurs in the?
Heart, neck, or brain. It can also be a blood vessel
Why does the blood not clot inside uninjured vessels?
The tissue beyond may have a lower blood flow or no blood flow. This can result in the death of the tissue. Strokes in the brain are the results of some of these actions.
Is plavix an anti-coagulant medication?
Plavix keeps the platelets in your blood from coagulating (clotting) to prevent unwanted blood clots that can occur with certain heart or blood vessel conditions.
What are the Buffering effect of blood plasma?
This occurs because there is no clotting factor or blood cell in the serum. The blood serum would only contain the blood plasma.
What starts the clotting process?
Coagulation of the blood begins with the activation of platelets - protoplasmic bodies that aid in the clotting of blood. These particles are part of blood composition at all times, but only coagulate when a blood vessel is injured. The injury triggers chemical signals which in turn draw collagen and platelets to the site of the wound and eventually build a structure to prevent blood loss.
