Answer:
Platelet enters the blood by its activation and followed by its sticking together with proteins in the blood. Inside each platelet are storage spaces called granules. When the platelet changes shape, chemicals (serotonin, epinephrine, histamine, and thromboxane) inside the granules are pushed out into the bloodstream.
Explanation:
Platelets:- They are tiny blood cells which helps in clot formation, hence preventing bleeding. They are produced from very large bone marrow cells called megakaryocytes. A normal count ranges from 150,000 to 450,000 platelets per micro liter of blood. if a blood vessel is damaged, it sends the signal to the platelet cells in the body, which then sense the signal and rush towards the site of damage to forma plug or clot. The clot formation fix the damage which in turn prevents blood clot.
Chemicals present in platelet:- Platelets store and transport several chemicals or factors, including serotonin, epinephrine, histamine, and thromboxane upon activation these molecules are released and helps in local blood vessel constriction, which initiates clot formation.
How Platelets enter the blood?
This is also known as platelet activation. Activated platelets can stick to each other and to clotting proteins in the blood. Inside each platelet are storage spaces called granules. When the platelet changes shape, chemicals (serotonin, epinephrine, histamine, and thromboxane) inside the granules are pushed out into the bloodstream.
Answer:
Platelets are the thread like component of the formed elements of the blood. Platelets are important for the blood clot formation and stops bleeding naturally after any injury.
The platelet activation process helps in the entrance of the platelets in the blood. The platelet must pass through the bone marrow wall of the capillary and reaches at the site of injury that helps in the platelet plug and clot formation.
