-혈소판은 출혈과 세균이 상처를 통해 몸 안으로 들어오는 것을 방지하는 중요한 역할을 한다. 혈소판은 딱지와 혈전을 만드는데 딱지와 혈전은 피가 밖으로 새어나오는 것을 막아준다.이런걸 지혈 또는 응고라고 하며,이 기능을 혈소판이 해준다.

How to Increase Platelet Count? Ways to Increase Platelet Count
A normal platelet count is between 150,000 and 400,000 platelets per microliter of blood. A platelet count less than 150,000/mm is considered low (thrombocytopenia), and a count higher than 400,000/mm is considered high (thrombocytosis). A platelet count test, usually part of a complete blood count (CBC), measures the number of platelets in a blood sample.
Normal Platelet Count: 150,000 to 400,000 platelets per microliter of blood.
===
Low Platelet Count (Thrombocytopenia): Less than 150,000 platelets per microliter.
Symptoms can include easy bruising, petechiae (tiny red spots under the skin), and excessive bleeding.
Causes can be inherited or acquired, and sometimes the cause is unknown.
High Platelet Count (Thrombocytosis): More than 400,000 platelets per microliter.
===
Can be due to various factors, including iron deficiency, infections, surgery, cancer, certain medications, and bone marrow diseases.
Why Platelet Count Matters: Platelets are essential for blood clotting and stopping bleeding. Abnormal platelet counts can indicate underlying health issues or increase the risk of bleeding or clotting problems.

혈소판은 혈관 벽의 손상부위에 모여 혈관으로부터의 혈액 유출을 막는 지혈작용에 관여하여 혈관기능이 유지되도록 합니다. 골수에서 생성되며 비장과 간이 파괴 장소입니다. 말초혈액 내 혈소판은 부정형이며 크기는 1-5㎛이고 용적은 5-12㎛3입니다.
골수 내에서 조혈모세포가 분화해 직접 만들어지는 적혈구, 백혈구와 달리 골수 내에서 거대핵세포(megakaryocyte)의 세포질 일부가 쪼개져 혈액으로 방출되어 생성된다.
혈구의 일종. 혈관의 파괴 등으로 혈액이 유출될 때, 혈액의 유출을 막는 고형의 세포 조각. 크기는 0.5-2.5μm 정도로 혈액 1L당 150~370×10 9개 정도 존재한다.

Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a part of blood whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping to form a blood clot.[1] Platelets have no cell nucleus; they are fragments of cytoplasm from megakaryocytes which reside in bone marrow or lung tissue,[2] and then enter the circulation. Platelets are found only in mammals, whereas in other vertebrates (e.g. birds, amphibians), thrombocytes circulate as intact mononuclear cells.[3]: 3
The ligands, denoted by letter L, signal for platelets (P) to migrate towards the wound (Site A). As more platelets gather around the opening, they produce more ligands to amplify the response. The platelets congregate around the wound in order to create a cap to stop blood flow out of the tissue.
One major function of platelets is to contribute to hemostasis: the process of stopping bleeding at the site where the lining of vessels (endothelium) has been interrupted. Platelets gather at the site and, unless the interruption is physically too large, they plug the hole. First, platelets attach to substances outside the interrupted endothelium: adhesion. Second, they change shape, turn on receptors and secrete chemical messengers: activation. Third, they connect to each other through receptor bridges: aggregation.[4] Formation of this platelet plug (primary hemostasis) is associated with activation of the coagulation cascade, with resultant fibrin deposition and linking (secondary hemostasis). These processes may overlap: the spectrum is from a predominantly platelet plug, or "white clot" to a predominantly fibrin, or "red clot" or the more typical mixture. Berridge adds retraction and platelet inhibition as fourth and fifth steps,[5] while others would add a sixth step, wound repair.[citation needed] Platelets participate in both innate[6] and adaptive[7] intravascular immune responses.
In addition to facilitating the clotting process, platelets contain cytoki
