When you get a cut in your skin, blood clotting is triggered by a complex series of reactions involving platelets and clotting factors. Platelets adhere to the exposed tissue at the injury site and release chemical signals that attract more platelets. This aggregation forms a temporary plug, while clotting factors activate a cascade that ultimately leads to the conversion of fibrinogen to fibrin, creating a stable mesh that solidifies the clot and helps seal the wound. This process is essential for preventing excessive blood loss and initiating healing.
Platelets.
When you get a cut or scratch, your body immediately sends blood to the area to stop bleeding. The body then forms a clot to seal the wound and begins to create new tissue to repair it. Over time, the wound will heal and new skin will grow over it, usually leaving a scar.
If blood wouldn't clot then when someone got a cut his blood would never stop leaking from it. Now that the blood does clot the hole will be filled up and the blood would stop.
the clot
When you have a cut on your body, blood oozes out due to the rupturing of blood vessels in the affected area. The body's natural response is to form a clot to stop the bleeding and begin the healing process. Platelets in the blood help to create a clot by sticking together and sealing the broken blood vessels.
The flow of blood to tissues beyond the clot may be cut off
The same process that creates problem blood clots leading to strokes are the same helpful processes that stops bleeding from a cut. The body sends platelets to the area. Platelets create a sticky cohesion between blood components and red blood cells. Macrophages rush to the area to begin cleaning up debris. The bleeding is stopped with the clot; healing begins. In a problem clot inside a blood vessel, the platelets' stickiness attacts more red blood cells. The blood components in the blood stream get caught against the clot, making it thicker. If the clot dislodges, it can travel to the heart or brain. Luckily, with a cut, the body reabsorbs the platelets and red blood cells that stuck together to make the clot. Soon, the clot is gone, the skin heals.
If a clot forms in a blood vessel it would be harmful as pressure would rise. Also, if the clot completely clogs an artery or vein blood cannot pass and you could die from lack of oxygen/circulation.

I think so
Vitamin K in the blood helps the blood to clot.
