Platelets, also known as thrombocytes, are tiny, colorless cell fragments found in our blood. They are essential for blood clotting and play a crucial role in preventing bleeding. When a blood vessel is damaged, platelets rush to the site of the injury and stick together to form a plug that helps stop the bleeding.
Here are some key points about platelets:
- Small & Colorless: They are the smallest component of our blood, and they lack a nucleus.
- Important for Clotting: Their primary function is to stop bleeding by forming clots.
- Activated by Injury: When a blood vessel is damaged, it releases signals that activate platelets.
- Forming a Plug: Activated platelets stick together at the injury site, forming a plug to seal the blood vessel.
Platelets are vital for our health. They help us survive surgeries, fight infections, and prevent excessive bleeding. When someone has a low platelet count, they are at risk of bleeding easily.
