Biology Artificial Blood Essay

654 words - 3 pages

MAB 2.3.4 and 2.3.5Analyse information from secondary sources to identify the products extracted from donated blood and discuss the uses of these products.
Products

Uses of these products

Red Blood Cells (RBC)

RBCs help to carry more oxygen. RBCs may also be used to help replace cells lost following significant bleeding.

Platelet Concentrate

Platelets are essential for the coagulation of blood and are used to treat bleeding caused by conditions or diseases where the platelets are not functioning properly.

Fresh Frozen Plasma (FFP)

FFP is mostly used to provide blood components that coagulate the blood. FFP contains all coagulation elements in normal amounts and is also free of red cells, white blood cells and platelets. It is used is used in treatments such as warfarin therapy (blood thinning) or when massive transfusions have taken place to provide a clotting effect.

Cryoprecipitate Anti-Haemophilic Factor

Cryoprecipitate AHF is a concentrate of clotting proteins and is used for the treatment of von Willebrand disease (similar to haemophilia), replacement of the clotting proteins, fibrinogen, Factor XIII and Factor VIII when no other option is successful.

Analyse and present information from secondary sources to report on progress in the production of artificial blood and use available evidence to propose reasons why such research is needed.Investigate the following substances before answering the questions below.

What is artificial blood?Artificial blood is a product made to mimic or act like a substitute for red blood cells which could be transfused into patients to temporarily provide some of the essential life-giving functions of blood until the patient's bone marrow could make enough blood to replenish their normal supply.How close are we to developing artificial blood? What has been achieved so far?Society is...

The artificial heart can keep patients stable for 1 to 4 years, the longest a patient had the SynCardia was 1,374 days (syncardia). The SynCardia is very reliable and has a failure rate of less than 1%. The bioprosthetic is the only device that provides immediate blood flow when a heart fails. The artificial heart combines synthetic

Organisms that have been created by this process of genetic engineering are considered to be genetically modified organisms (Biology-Online, 2014). Today, gene manipulation is impacting nursing and the healthcare field in many ways. The advancements contributed to gene manipulation will enable the human

Additionally, transfusing of young blood can maintain aging for mice. Although we still do not know whether all aspects of Huxley’s brave new world can be achievable or not, a biologist Needham argued that “the book very accurately predicted how biology and psychology could

What is Molecular Biology?

1868 words - 8 pages MOLECULAR BIOLOGY INTRODUCTION AND BACKGROUND INFORMATION Molecular biology is to characterize the structure, function and relationships between two types of macromolecules, DNA and proteins. This relatively limited definition will suffice to allow us to establish a date for the so-called "molecular revolution", or at least to establish a chronology of its most fundamental developments (Walker, 2009) .At the heart of this definition is the idea

Are We Now Living in Aldous Huxley’s Brave New World?

1253 words - 6 pages article written by Fackelmann, “the word "clone" comes from a Greek word that means "twig" and suggests the practice of slicing off a piece of a plant and rooting it” (Fackelmann 92). Thus, cloning has a strong association with plants historically. In addition to artificial clones, there are clones which are naturally produced. For instance, monozygotic twins are treated as clones because they are produced from a single embryo, so that they
