Platelets are non-nuclear units. In blood, most of the platelets has a characteristic discoid shape. Discoid shape is supported at the platelet circular microtubular ring. The platelet has 4 main functional areas. The first peripheral area, is a phospholipid bilayer membrane and the space adjacent to it on both sides. The Sol-gel zone is a viscous matrix of the platelet cytoplasm, adhering to submembranous area. Area organelles, includes organelles located throughout the cytoplasm in an inactive platelets. The area of the membrane, consists of channels dense tubular system, resembling the structure miltenovasarcoplasmatic reticulum. Platelets are the basis of all primary hemostasis due to their ability by aggregation trombirovania damage in the blood vessels. Forming a dynamic aggregates, platelets affect the rheological properties of blood and thus on the state of the trophism of tissues throughout the body. 107 108
