Blood is the red liquid that is present throughout the human body without exception. It is called blood (the fluid of life) because of its great and important function within the body and for its tremendous ability to reach all the cells and tissues because it can supply oxygen to breathe and the food necessary for it to remain healthy. It excludes carbon dioxide, and later excretions. Blood functions also transfer hormones from the glands to other parts of the body to complete many of the vital processes that occur within it. Blood consists of four main components: red blood cells, white blood cells, plasma, and platelets, which we will discuss in this article.
Platelets are the main components of blood. They are flat segments of the cytoplasm with irregular and irregular shapes that are estimated to be 3 nanometers in diameter. They do not contain a nucleus or any organ, so they can never be considered cells and live in blood at a Between 7 and 10 days, and is the second most common components of blood, as the number of plates per cubic meter is about 150000 to 400000, and the platelets are produced from the bone marrow.
The importance of platelets in their ability to form the so-called clots or blood clots in the event of bleeding, when the occurrence of any bleeding direct signs of induction of thrombosis to the platelets to stick and bonding between them to stop bleeding.
Platelets must be present in the blood at normal rates. Any decrease in human exposure can lead to several health problems, and platelet insufficiency is a breakage of these platelets directly from the bone marrow, or passing through the vessels. The immune system does not distinguish between platelets and other foreign bodies so it attacks and destroys them, or there may be a lack of production of bone marrow originally, due to the lack of platelets to:
- Infection with certain viruses, such as smallpox and colds.
- The incidence of lupus erythematosus.
- Defective immune system.
- Take certain medications without medical advice.
The symptoms of platelet insufficiency are the appearance of blue bruises on the patient’s body, and persistent suffering from chronic bleeding in the gums, nose, or digestive tract. The most serious hemorrhage is brain hemorrhage, but it is rare.
