What are platelets and what do they do?
Platelets, or thrombocytes, are tiny blood cells that bud from cells in the bone marrow (megakaryocytes). Platelets form clots when there’s damage to a blood vessel. For example, if you cut your finger, platelets mix with clotting factors (proteins in the blood). Together, they form a “glue” that stops the bleeding.

What two functions are platelets used for?
Platelets function in the control of bleeding by clogging and clumping in response to blood vessel that has been injured. The blood component perform the role during the blood clotting process with the help of other coagulation factors within the blood system.
How and where are blood platelets produced in the body?
Platelets, or thrombocytes, are produced in the bone marrow by giant cells called megakaryocytes. When megakaryocytes reach their full size, they start to fall apart and release hundreds of small platelets. The hormone thrombopoeitin (TPO) controls the growth of megakaryocytes and platelet production.

How are platelets formed?
Platelets are produced from very large bone marrow cells called megakaryocytes. As megakaryocytes develop into giant cells, they undergo a process of fragmentation that results in the release of over 1,000 platelets per megakaryocyte.
What is the function of platelets and how are they formed?
Platelets originate in bone marrow and circulate in our blood. Their primary function is to prevent and stop bleeding. If a blood vessel is damaged, the body sends signals to platelets which cause them to travel to the injured area.
What is an platelet?
(PLAYT-let) A tiny, disc-shaped piece of cell that is found in the blood and spleen. Platelets are pieces of very large cells in the bone marrow called megakaryocytes. They help form blood clots to slow or stop bleeding and to help wounds heal.
When are platelets formed?
Platelets are produced during hematopoiesis in a sub-process called thromopoiesis, or production of thrombocytes. Thrombopoiesis occurs from common myeloid progenitor cells in the bone marrow, which differentiate into promegakaryocytes and then into megakaryocytes.
What causes platelets to drop?
Conditions that cause blood clots, such as thrombotic thrombocytopenic purpura (TTP) and disseminated intravascular coagulation (DIC), can cause your body to use up all your platelets. This leads to a low platelet count. Infections from bacteria and viruses can lower your platelet count for a while.
What happens when platelets are too low?
Dangerous internal bleeding can occur when your platelet count falls below 10,000 platelets per microliter. Though rare, severe thrombocytopenia can cause bleeding into the brain, which can be fatal.

What is the function of platelets short answer?
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.
Which cells platelets are formed from?
Platelets come from larger progenitor cells called megakaryocytes, and platelet production represents the final stage of megakaryocyte development (Fig.
10 Causes of High Platelet Count - Thrombocyte.com
Platelets are small, oval/spherical component of the blood that don’t have its own nucleus. These small fragments are produced in the bone marrow and plays a very important part in blood clotting. Normal levels of platelets in the blood is about 150-450×10 9 / L of blood. There are several factors that influence platelet life span but normally goes for only 7-10 days.
Platelets: Definition, Functions and Importance - Healthtian
Platelets can also be known as thrombocytes which is part of the components of blood. It also forms the element of blood which includes erythrocytes ( red blood cells), leucocyte (white blood cells), and thrombocytes (platelets itself). Platelets have a peculiar function of initiating blood clotting. Blood clotting is the process by which blood loses its liquid state or fluidity.
What is platelet count?
A platelet count is a quick, common test that measures how many platelets are in your blood. Platelets, or thrombocytes, are tiny blood cells that bud from cells in the bone marrow (megakaryocytes). Platelets form clots when there’s damage to a blood vessel. For example, if you cut your finger, platelets mix with clotting factors (proteins in the blood). Together, they form a “glue” that stops the bleeding. There are tens of thousands of platelets in a single drop of blood.
What does a low platelet count mean?
Platelets are cells that help your blood clot. A low platelet count might be a sign of certain cancers or infections. A high platelet count can put you at risk for harmful blood clots or stroke.

Does chemotherapy cause low platelet count?
Low platelet count is a major side effect of cancer treatment. Some types of chemotherapy can damage bone marrow, reducing platelet production. ( This damage is usually temporary.) Other times, the cancer itself causes the problem. Leukemia and lymphoma can invade the bone marrow and prevent the patient’s body from producing the platelets it needs.
What is a healthy platelet count?
A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia. You get your platelet number from a routine blood test called a complete blood count (CBC).
What causes platelets to increase?
The medical term for having too many platelets is thrombocytosis, and there are two types: 1 Primary or essential thrombocytosis – Abnormal cells in the bone marrow cause an increase in platelets, but the reason is unknown. 2 Secondary thrombocytosis – The same condition as primary thrombocytosis, but may be caused by an ongoing condition or disease such as anemia, cancer, inflammation, or infection.
