Short answer is collagen fibres.
Collagen is the most prevalent protein in the body. When tissue is torn, these collagen fibres are exposed. Platelets are attracted to the exposed fibres. Once a platelet has made contact with the fibres, the platelet becomes active, and other platelets can stick to it until a plug has been formed.

When the innermost wall of the vessel is damaged what begins to repair by attaching to the damaged site?
the platelets in the blood.
What is the function of platelets in circulatory system?
Platelets are blood cells that help stop bleeding. When we cut ourselves we have broken a blood vessel and the blood leaks out. In order to plug up the holes where the blood is leaking from the platelets start to stick to the opening of the damaged blood vessels. As the platelets stick to the opening of the damaged vessel they attract more platelets, fibers and other blood cells to help form a plug to seal the broken blood vessel. When the platelet plug is completely formed the wound stops bleeding. We call our platelet plugs scabs.
What is the tiny cell fragments in blood?
Platelets are tiny cell fragments in the blood that play a key role in blood clotting. They help to stop bleeding by clumping together at the site of a damaged blood vessel to form a plug.
The primary sealant that plugs leaks in blood vessels is?
When a blood vessel is damaged, tissue factor and von-Willebrand's factor are exposed, causing platelets to adhere to the area. These platelets are then activated, which causes more platelets to stick and fibrinogen to be converted to fibrin, which makes a solid seal over the damaged area.
When tissue lining a blood vessel is damaged the first thing that happens is?
When tissue lining a blood vessel is damaged, the platelets in the blood stick to the damaged area, forming a plug to stop bleeding. This is part of the initial response to injury known as hemostasis.
What is blood platelet plug formation?
Blood platelet plug formation is the process by which platelets in the blood adhere to the site of a damaged blood vessel, become activated, and aggregate to form a plug that helps stop bleeding. This plug is a temporary seal until more permanent blood clotting can occur to heal the damaged vessel.
How blood clotting prevent inside human body?
Normally the beginning of a blood clot, platelet plug formation, doesn't occur unless the platelets are exposed to the underlying collagen fibers. That doesn't happen unless the blood vessel has been damaged so clots usually only occur in response to a damaged blood vessel.
What cells are responible for clotting?
Platelets, also called thrombocytes, are responsible for blood clotting. When a blood vessel is damaged, platelets become activated and form a plug at the site of injury to stop bleeding. They also release chemicals to help in the clotting process.
What is required to help clot blood?
Platelets (thrombocytes) are not complete cells. Rather, they are fragments of giant cells present only in bone marrow. when a blood vessel is damaged, platelets form a plug that seals the vessel, and injured tissues release molecules that help the clotting process.
Platelets are used for what?
Platelets are the cells that circulate within our blood and bind together when they recognize damaged blood vessels.
What is the function of the blood platelets?
Platelets help close breaks in damaged blood vessels and initiate formation of blood clots.
What formed element is the first to play a role in sealing an injury to a blood vessel?
Platelets are the formed elements that have a role in blood clotting, and would seal an injury to a vessel walls. The platelets are cell fragments. Platelets are also known as thrombocytes.
