is a place where blood is collected from donors, typed, separated into components, stored, and prepared for transfusion to recipients. A blood bank may be a separate free-standing facility or part of a larger laboratory in a hospital.

Separation of blood

Typically, each donated unit of blood (whole blood) is separated into multiple components, such as red blood cells, plasma and platelets. Each component is generally transfused to a different individual, each with different needs.

An increasingly common blood bank procedure is apheresis, or the process of removing a specific component of the blood, such as platelets, and returning the remaining components, such as red blood cells and plasma, to the donor. This process allows more of one particular part of the blood to be collected than could be separated from a unit of whole blood. Apheresis is also performed to collect plasma (the liquid part of the blood) and granulocytes (white blood cells).

Who receives blood: Accident victims, people undergoing surgery and patients receiving treatment for leukemia, cancer or other diseases, such as sickle cell disease and thalassemia, all utilize blood.

Giving blood to yourself: Patients scheduled for surgery may be eligible to donate blood for themselves, a process known as autologous blood donation. In the weeks before non-emergency surgery, an autologous donor may be able to donate blood that will be stored until the surgical procedure.

Typing and testing blood: After blood is drawn, it is tested for the ABO Blood Group type and the Rh type (positive or negative), as well as for any unexpected red blood cell antibodies that may cause problems in the recipient. Screening tests are also performed for evidence of donor infection with hepatitis viruses B and C, human immunodeficiency viruses (HIV) 1 and 2, human T-lymphotropic viruses (HTLV) I and II and syphilis.

Storage of blood: Each unit of whole blood is normally separated into several components. Red blood cells may be stored under refrigeration for a maximum of 42 days, or they may be frozen for up to 10 years. Red cells carry Oxygen and are used to treat anemia. Platelets are important in the control of bleeding and are generally used in patients with leukemia and other forms of cancer. Platelets are stored at room temperature and may be kept for a maximum of five days. Fresh frozen plasma, used to control bleeding due to low levels of some clotting factors, is usually kept in the frozen state for up to one year. Cryoprecipitated AHF, which contains only a few specific clotting factors, is made from fresh frozen plasma and may be stored frozen for up to one year. Granulocytes are sometimes used to fight infections, although their efficacy is not well-established. They must be transfused within 24 hours of donation.

Functions of lymph system

The lymphatic system has three primary functions:

Fluid balance

The lymphatic system helps maintain fluid balance. It returns excess fluid and proteins from the Tissues that cannot be returned through the blood vessels. The fluid is found in tissue spaces and cavities, in the tiny spaces surrounding cells, known as the interstitial spaces. These are reached by the smallest blood and lymph capillaries.

Around 90 percent of the plasma that reaches tissues from the arterial blood capillaries is returned by the venous capillaries and back along veins. The remaining 10 percent is drained back by the lymphatics.

Each day, around 2-3 liters is returned. This fluid includes proteins that are too large to be transported via the blood vessels. Loss of the lymphatic system would be fatal within a day. Without the lymphatic system draining excess fluid, our tissues would swell, blood volume would be lost and pressure would increase.

Absorption

Most of the fats absorbed from the gastrointestinal tract are taken up in a part of the gut membrane in the small intestine that is specially adapted by the lymphatic system.

The lymphatic system has tiny lacteals in this part of the intestine that form part of the villi. These finger-like protruding structures are produced by the tiny folds in the absorptive surface of the gut. Lacteals absorb fats and fat-soluble VITAMINS to form a milky white fluid called chyle.

This fluid contains lymph and emulsified fats, or free fatty acids. It delivers nutrients indirectly when it reaches the venous blood circulation. Blood capillaries take up other nutrients directly.

The immune system

The third function is to defend the body against unwanted organisms. Without it, we would die very soon from an infection.

Our bodies are constantly exposed to potentially hazardous micro-organisms, such as infections.

The body's first line of defense involves:

physical barriers, such as the skin
toxic barriers, such as the acidic contents of the stomach
"friendly" bacteria in the body

However, pathogens often do succeed in entering the body despite these defenses. In this case, the lymphatic system enables our immune system to respond appropriately. If the immune system is not able to fight off these micro-organisms, or pathogens, they can be harmful and even fatal. A number of different immune cells and special Molecules work together to fight off the unwanted pathogens.

Blood banks are facilities that collect, store, and transfuse blood and blood products. They play a vital role in the healthcare system, providing blood to patients who need it for surgery, trauma, and other medical conditions.

Blood donation is the process of donating blood to a blood bank. Blood donors are typically healthy adults who meet certain eligibility requirements. The donation process is safe and relatively painless, and it can save lives.

Blood transfusion is the process of transferring blood or blood products from one person to another. Blood transfusions are used to treat a variety of medical conditions, including anemia, hemorrhage, and cancer.

Blood typing is the process of determining a person’s blood type. Blood type is determined by the presence or absence of certain antigens on the surface of red blood cells. There are four main blood types: A, B, AB, and O.

Blood components are the different parts of blood that can be transfused. Blood components include red blood cells, plasma, platelets, and white blood cells.

Blood storage is the process of keeping blood and blood products safe and viable for transfusion. Blood is typically stored in a blood bank at a temperature of 4 degrees Celsius.

Blood Banking equipment is the equipment used in blood banks to collect, store, and transfuse blood and blood products. Blood banking equipment includes blood collection bags, blood storage refrigerators, and blood transfusion pumps.

Blood banking Software is the software used in blood banks to manage blood donation, blood inventory, and blood transfusion. Blood banking software helps blood banks to track blood donations, blood inventory levels, and blood transfusions.

Blood banking regulations are the regulations that govern the collection, storage, and transfusion of blood and blood products. Blood banking regulations are designed to ensure the safety and quality of blood and blood products.

Blood banking ethics are the ethical principles that guide the practice of blood banking. Blood banking ethics are designed to protect the rights of blood donors and blood recipients.

Blood banking research is the research that is conducted to improve the safety and quality of blood and blood products. Blood banking research is also conducted to develop new blood products and treatments.

Blood banking history is the history of the development of blood banks and blood transfusion. Blood banking began in the early 20th century, and it has evolved significantly since then.

Blood banking organizations are the organizations that represent blood banks and blood bankers. Blood banking organizations work to improve the practice of blood banking and to promote the safety and quality of blood and blood products.

Blood banking statistics are the statistics that are collected on blood donation, blood inventory, and blood transfusion. Blood banking statistics are used to track the blood supply and to identify areas where blood donation is needed.

Blood banking controversies are the controversies that surround blood donation, blood storage, and blood transfusion. Blood banking controversies include the issue of blood donation compensation, the issue of blood product safety, and the issue of blood supply shortages.

Blood banking future is the future of blood banking and blood transfusion. Blood banking is facing a number of challenges, including the aging Population, the rise of chronic diseases, and the shortage of blood donors. Blood banking is also facing a number of opportunities, including the development of new blood products and treatments, the use of new technologies, and the expansion of international blood donation.
