what is the function of a thrombocyte
Answers
Explanation:
Platelets, also called thrombocytes (from Greek θρόμβος, "clot" and κύτος, "cell"), are a component of blood whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot.
Answer:
(1) Thrombocytes or platelets are non- nucleated, round and biconvex blood corpuscles.
(2) They are smallest corpuscles measuring about 2.5 to 5 mm in diameter with a count of about 2.5 lakhs/cu mm of blood.
(3) Their life span is about 5 to 10 days.
(4) Thrombocytes are formed from megakaryocytes of bone marrow. They break from these cells as fragments during the process of thrombopoiesis.
(5) Thrombocytosis is the increcase in platelet count while thrombocytopenia is decrease in platelet count.
(6) Thrombocytes possess thromboplastin which helps in clotting of blood.
(7) Therefore, at the sile of injury platelets aggregate and form a platelet plug
