5 Μαρ 2019 · Platelets are small cells that stop bleeding by forming clots; they are essential for those fighting cancer, disease and traumatic injuries. Cancer, trauma, transplant and burn patients all use platelets in order to survive.
One major function of platelets is to contribute to hemostasis: the process of stopping bleeding at the site of interrupted endothelium. They gather at the site and, unless the interruption is physically too large, they plug the hole. First, platelets attach to substances outside the interrupted endothelium: adhesion.
Platelets are special blood cells tasked with preventing too much blood loss. These small and colorless structures are also known as thrombocytes and resemble cell fragments.
7 Αυγ 2023 · Platelets play an important role in the formation of blood clots. They are commonly described as cellular fragments – they are not true cells as they do not contain a nucleus or carry nuclear DNA, although they do contain mitochondria. Platelets have a life span of 7-10 days.
