What two substances are found in the blood during clotting?
This is for any annoyed students that can't find the answer. The two parts of the blood that are involved in blood clotting is Plasma Platelets
List two components of blood that make clotting possible?
Platelets and proteins.
What are Proteins C and S?
Proteins C and S are two of the clotting factors that are present in the plasma to help regulate or activate parts of the clotting process
What is blood clotting?
There are the intrinsic and extrinsic pathways in clotting. The intrinsic pathway is initiated when blood comes in contact with damaged endothelium or collagen, and involves clotting factors XII, XI, IX, and VIII. The extrinsic pathway is activated when being exposed to tissue factor from tissue injury or the addition of thromboplastin to blood, and involves clotting factor VII. The two pathways meet at the point of clotting factor X activation to lead the final common pathway. From here, factor X is converted to prothrombin, prothrombin to thrombin, thrombin to fibrinogen, fibrinogen to fibrin, and finally fibrin to fibrin clot. Platelets, activated by thrombin, adhere to the damaged endothelium wall or collagen to form a plug. At the same time, they activate clotting factors VII and X. More platelets are stimulated by fibrin clots, resulting in reinforcing the formed clots.
Does ice directly over an open wound inhibit clotting?
No. Ice on an open wound actually HELPS clotting. Lowering the local temperature, ice stimulates a heat-loss reflex that significantly reduces blood flow by constricting arterioles. (This causes the cold tissue to appear light in color. And it's also why ice is helpful in first aid for closed injuries, to prevent swelling.) The reduced blood flow allows the clot to form and stick without washing away. You might guess ice would inhibit clotting, because low temperature decreases two processes important in clotting: release of clotting factors by blood platelets, and the enzyme reactions that actually convert liquid blood into a clot. However, these two reactions are only slightly affected by cold, while local blood flow is dramatically reduced by cold. In contrast to ice, mild heat inhibits clotting by increasing local blood flow.
How does tannic acid stop bleeding?
The Tannic acid helps to form a blood clot by contracting blood vessels. Amr ^_^Actually, blood clotting is the result of a "cascade" effect of different factors in the blood. Once activated they "domino" -- one activates the next in the chain -- until the blood clots. There are two pathways to blood clotting (coagulation) -- an intrinsic pathway and an extrinsic (external) pathway. Tannic acid acts to activate the extrinsic pathway and set the factor "cascade" in motion to clot the blood.
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.
What two factors make gravity stronger or weaker?
The amount of mass involved and the distance between the two objects involved.
How does styptic powder work?
I would submit that it is a result of one of two mechanisms or possibly a combination of the two.....namely........potent vasoconstriction of cutaneous blood vessels and /or it promotes blood clotting or coagulation of the blood. Allen Duplantis MD
What is the difference between Hemophilia A and Hemophilia B?
There are two types of hemophilia: hemophilia A (sometimes called classical hemophilia) and hemophilia B (sometimes called Christmas disease). Both are caused by a low level or absence of one of the proteins in the blood (called factors) that control bleeding. Hemophilia A is caused by a deficiency of factor VIII, and hemophilia B is caused by a deficiency of factor IX. There is no difference between the two types of hemophilia, except that hemophilia B is about five times less common than hemophilia A.
What is plasma used for?
There are two types of Plasma.Matter Plasma is a form of ionized matter stripped of electrons. This is what is found in the core of the sun.A plasma cutter is used in welding, and superheats gasses to create plasma. See the article on "How Stuff Works".http://home.howstuffworks.com/plasma-cutter.htmHowever, another term for Plasma is the liquid component in the blood. It includes minerals, proteins, and clotting factors.Perhaps the most useful part would be the clotting factors which can be useful for surgery or certain types of traumatic injury, or for the treatment of hemophilia, a disease that is characterized by a deficiency of clotting factors causing excess bleeding.
Why does liver diseases cause blood clotting disorders?
The liver produces the factors that initiate clotting of the blood ( actually,it produces all the plasma proteins except gamma globulins). If the liver is compromised, it will not be able to produce these factors. Liver cancer or hepatitis are two conditions that will impair/ compromise the liver andits functions. Therefore, even a simple injury may be extremely dangerous for an individual who may have either one of these conditions, since the bleeding will not be stopping as easily as it should. Remember, we bleed all the time for a variety of reasons: Scrapes, cuts, hemorrhages, and even when you brush your teeth :)Also research : HemophiliaThank youSelcuk Ipek BMCC
