What is the function platelets?
- AIt binds to oxygen
- BIt binds to carbon dioxide
- CIt forms cyanide in body
- Correct answerDIt leads to coagulation of blood
Solution
Platelets, also known as thrombocytes, are cell fragments found in the blood that play a crucial role in the process of hemostasis.
When a blood vessel is injured, platelets adhere to the site of the injury and aggregate to form a platelet plug.
They release various chemical factors that activate the clotting cascade, which leads to the conversion of fibrinogen into fibrin threads, thereby forming a stable clot.
This process is known as the coagulation of blood, which prevents excessive bleeding.
