Platelets are sometimes called . Platelets are continually produced in the by . Normally, the concentration of platelets in an adult ranges from , although the count may rise further during times of stress. Platelets can circulate in the blood for 8 to 10 days, unless they are needed earlier for blood clotting. An abnormally small number of platelets in circulating blood is termed .

The correct order of answers are: thrombocytes, red bone marrow, megakaryocytes, 150,000-400,000, thrombocytopenia.

Explanation:

Platelets are small blood cells that form clots to stop the body from bleeding. When a blood vessel gets damaged, signals are sent to the platelets. The platelets then rush to the site of damage. they form a plug (clot) to help fix the damage.

The process of platelets spreading across the surface of a damaged blood vessel to control bleeding is known as adhesion. This occurs because when platelets arrive at the site of the injury, they grow sticky tentacles that help them stick to each another. They also have the ability send out chemical signals to attract more platelets.
