• They are fragments of protoplasm.

• They are derived from Megakaryocyte cells of bone marrow.

• They are oval or bi-convex in shape.

• They can be stained by methylene blue.

• Life span of platelets is 2-5 days.

• They repair endothelium of blood vascular system by the formation of platelet plug.

$\huge\mathbb{\underline{\underline{ANS} \red {\underline{ \underline{WER:}}}}}$

• 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.

$\huge→$Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.
