No. They are cells that help heal wounds on your skin. Blood vessels are arteries and veins.
Actually within blood vessels. Though megakaryocytes, the mothers of platelets grow in the bone marrow, but they send pseudopodia into the adjoining blood vessels and release the platelets, which are actually fragments of the pseudopodia. So, in the blood vessels.
Without platelets your blood vessels would not heal if they were torn and you would lose blood and die.
Platelets are the cells that circulate within our blood and bind together when they recognize damaged blood vessels.
Platelets are also known as thrombocytes. One of their main functions is blood coagulation. Formation of thrombocytes or platelets occure when the endothelium is damaged. The endothelium is the inner lining of blood vessels. Therefore, platelets are formed within and by damaged blood vessels.
Platelets help close breaks in damaged blood vessels and initiate formation of blood clots.
Platelets
Blood cells and platelets are suspended in blood plasma (mostly water) and moved through the body in blood vessels (arteries, veins & capillaries). The blood is forced through the blood vessels by the heart.
Platelets are nuclear cells rotates the blood and get rid of blood clots.they release protein , and close up the tear in the blood vessels..
The platelets inside of blood preform this function.
It's not a blood cell. It is platelets. They clot due to blood loss from damaged blood vessels
Megakaryocytes are the bone marrow cells that produce platelets.
