Why do platelets initialy stick to the wall of a damaged blood vessel?

Well, platelets create a micro fibril when they come in contact with the ruptured vein/capillary walls, this fibril is i guess you can say sticky, from there they build up and create a mesh that in time creates a scab so no more blood is lost.

∙ 12y agoShort 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.
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.
Which of the blood cells make the blood clot?
It's not a blood cell. It is platelets. They clot due to blood loss from damaged blood vessels
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 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.
When a blood vessel is injured there are tiny what in the blood that helps clot blood and seal the blood from a cut?
these are known as platelets they are platelets are u dumb or have some type of something
Cell fragments that climp together to form a plug that helps reduce blood loss?
Cell fragments that clump together to help reduce blood loss are called platelets. These platelets are found floating in the blood stream. When a capillary or any kind of blood vessel is cut/damaged, chemicals are released and it in a way, calls out to the platelets to come and to start help form a plug to reduce blood loss from the injured spot.
How does blood clot?
When an injury tears open a blood vessel, blood platelts stick to the broken vessel. Fibrinogen gathers on the platelets and changes into a tangled network of fine threads, which in turn catches more platelts and blood cells. The platelets and Fibrinogen cause the blood to clot.
