Platelets are blood cells that help our body to form clots to stop bleeding. If our blood vessels gets damaged, it sends out signals that are picked up by platelets. The platelets rush to the site of damage and form a plug, or clot, to repair the damage.
Adhesion is the process of spreading across the surface of a damaged blood vessel to stop bleeding. When platelets get to the site of the injury, they grow sticky tentacles that help them adhere. Aggregation is the sending out of chemical signals to attract more platelets to pile onto the clot that helps in stopping the bleeding.
Platelets along with your white and red blood cells are made in your bone marrow. Bone marrow is the spongy center inside your bones. Platelets is also called thrombocytes.

Bleeding can occur under the skin as bruising, inside the body as internal bleeding, or outside the body through a cut that won't stop bleeding or from a nosebleed if platelet count gets too low.

• Thrombocythemia- is a condition in contrast with thrombocytopenia, our bone marrow makes too many platelets. Blood clots that form and block blood supply to the brain or the heart is one of the symptoms. The cause of thrombocythemia is unknown.

• Thrombocytosis- a condition caused by too many platelets, but platelet counts do not get as high as in thrombocythemia. More common and is not caused by abnormal bone marrow. The cause is another disease or condition in the body that stimulates the bone marrow to make more platelets. When the underlying condition gets better, the platelet count goes back to normal.

Platelets are tiny but important cells in your blood that help your body control bleeding. If you have symptoms such as easy bruising, a cut that keeps bleeding, or frequent nosebleeds, let your healthcare provider know. A simple blood test is all you need to find out if your platelet count is
