What Are Platelets? Function & Anatomy - Cleveland Clinic
网页2024年8月26日 — Platelets, also called thrombocytes, are tiny cell fragments in your blood that help with clotting. Platelets are your body’s natural bandage to stop bleeding if you’re injured. Just a single drop of your blood contains tens of thousands of platelets. It’s important that you have enough (but not too many) of them.
What Are Platelets and Why Are They Important?
网页Platelets, the smallest of our blood cells, can only be seen under a microscope. They’re literally shaped like small plates in their non-active form. A blood vessel will send out a signal when it becomes damaged. When platelets receive that signal, they’ll respond by traveling to the area and transforming into their “active” formation.
Platelet - Wikipedia
网页Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a blood component whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot. [1] Platelets have no cell nucleus; they are fragments of ...
Thrombocytopenia (low platelet count) - Symptoms and causes
网页2022年4月19日 — Platelets (thrombocytes) are colorless blood cells that help blood clot. Platelets stop bleeding by clumping and forming plugs in blood vessel injuries. Thrombocytopenia might occur as a result of a bone marrow disorder such as leukemia or an immune system problem.
Platelets (Thrombocytes): Function, Normal Values, and More
网页2024年9月9日 — Platelets, also known as thrombocytes, are special blood cells with an important function. Platelets control blood clotting, which means they are critical for healing wounds and stopping bleeding. A normal platelet count is 150,000–450,000 platelets per microliter. A low platelet count can put you at risk for uncontrolled bleeding.
