Blood Products
Blood products (/blʌd 'prɒdʌkts/) are components of blood used in transfusions, which are typically obtained through blood donation. They are used to replace lost components of the blood.
Etymology
The term "blood products" is derived from the English words "blood" and "product". "Blood" comes from the Old English blōd, which is of Germanic origin. "Product" comes from the Latin productum, which is the past participle of producere meaning 'to bring forth'.
Types of Blood Products
There are several types of blood products, including:
- Whole blood: This is blood that has not been separated into its component parts. It is rarely used in transfusions today.
- Red blood cells (RBCs): These are the most commonly used blood product. They carry oxygen from the lungs to the rest of the body.
- Platelets: These are small cell fragments that help the blood to clot. They are often used in treatments for cancer and other diseases that affect the blood's ability to clot.
- Plasma: This is the liquid part of the blood. It carries the blood cells and platelets, as well as nutrients, hormones, and waste products.
- Cryoprecipitate: This is a type of frozen plasma that is rich in clotting factors. It is often used to treat bleeding disorders.
- Granulocytes: These are a type of white blood cell that help fight infection. They are rarely used in transfusions.
