platelets
Platelets are cell fragments that lack a nucleus and are key players in the blood clotting process. They help to seal off leaks in damaged blood vessels by sticking to the injured area and releasing chemicals that promote clotting.
Platelets, or thrombocytes, are the smallest formed element in the blood. Made of cell fragments, platelets are part of the blood clotting process. Non-formed clotting factors also are critical to blood clotting.thrombocytes
Platelets are cell fragments that clump together to form a plug that helps reduce blood loss by sealing off small breaks in blood vessels.
The function of platelets is in clotting. Without them the blood would not clot. They are cell fragments and not cells. They live only 5-9 days. Too many platelets can cause clots that then can travel and cause blockages in vessels. Too few can cause uncontrolled bleeding.
If this clotting occurs in the larger arteries, it results in major tissue damage.
Also known as disseminated intravascular coagulation, this type of cardiovascular disease is a condition wherein there is excessive clotting and hemorrhage throughout the body and can lead to organ failure or worst, death
Blood clotting does occur for blood in uninjured blood vessels due to its insulation from air. Our bodies produce what is called heparin that prevents clotting of blood in vessels. Heparin allows our lungs to transfer oxygen to our blood. When blood is exposed to air it clots so heparin allows the blood to come in direct contact with the air we breath without clotting.
Clotting factors will be activated.
The organism not only damages the blood vessels by causing them to leak, but also causes clotting inside the vessels.

No, bones do not bleed when they are injured. Bones are made up of living tissue, but they do not have blood vessels like other parts of the body. When a bone is injured, the blood vessels surrounding the bone may bleed, but the bone itself does not.
