What Are Red Cells? Essay

1906 words - 8 pages

Introduction
Every adult has around five litres of blood inside them, accounting for around 8% of their total body weight. Usage of donated blood by transfusion was a 20th century phenomenon and has become a long established therapeutic necessity. Around 2,000,000 units are transfused each year in UK, red cells remaining by far the most commonly transfused blood productL.
There are many areas in which blood transfusions come useful – such as serious injuries, illnesses, operations, childbirth – and in the case of red cells, often in the case of severe anaemia and blood loss.
With an ageing population and increased number of therapeutic interventions, comes many consequences. More elderly people now present with illnesses and for surgery – which have become more elaborate and extensive, increasing the need for supply and risk of complications. Unfortunately, demand outstrips supply, especially with the increase cardiac surgery and coronary heart disease, and changes in practice, especially involving chemotherapy and stem-cell transplant regimens.
As one’s own body loses own capacity to make adequate red cells – with our own genetics prevent their formation – the implications of not transfusing are otherwise catastrophic, with no viable alternative to improve oxygen-carrying capacity of the blood.
The increasing demand for supply requires the need for new approaches to recruitment and retentiont of future generations of donors.1 Spirally costs due to safety procedures in place make sure that that allogeneic red cells must be restricted as an asset. (SS) Despite such measures, there remains the risk of transmitting infectious diseases and developing an immune reaction to donated blood.
The NHS spends about £500 million on producing blood components for transfusing each year, involving the processing of around 2.5 million blood donationsSS. However, many challenges are met in the supply and usage of such products to meet the increasing and potentially unsustainable demand.

Challenges in supply
Before application of science do work their medical wonders, there is the reliance for the donors to provide the supply, of which is a huge shortage. Around 1.6 million donate blood each year, which is only 4% of the eligible population, as reported by NHSB, with supplies plummeting during holiday periodsD,
Public from the age of 17 onwards are eligible to donate, yet the younger population is consistently declining. In addition, current and past donors constant age towards the division where they are more likely to become recipients, contributing to the unsustainability.
Thus the need to recruit donors for the present and future is vital – to enlist and retain.
With modern technology, donors and blood services can now interact in new ways. Awareness can be increased via leaflets given out in person, by post, email and text message. Social media networks such as Facebook and Twitter are social norms for blood services to use to. Websites have become more...

Sickle Cell Anemia and Red Blood Cell Physiology, Annotated Bibliography

1027 words - 5 pages hemoglobin due to a mutation in the hemoglobin chain. This type of hemoglobin is known as sickle hemoglobin or hemoglobin S. Sickle hemoglobin is what distorts red blood cells into a sickle shape. Sickle cells are sticky and less elastic than normal red blood cells. They are not able to pass through the blood as easily so in result they tend to block blood flow in blood vessels. Blocked blood flow causes pain, organ damage, and increases the risk for

Stem cell research offers the hope of transplants being done without the sacrifice of another person losing an organ. There are many different pros and cons when it comes to discussing the use of stem cells. In order to develop an opinion of whether or not stem cells should be used, one must first understand what they are and how they are used

Red Blood Cells

Hemoglobin contains iron, which is what is used to make the oxygen and molecule attach to me. If the hemoglobin were not in the cells, all of your blood would be yellow-colored. Once I pass through the body tissue, the hemoglobin releases all of the oxygen and molecules out to all of the cells. The

What makes these cells different from others is that they are capable of renewing themselves through cell division. As well, under certain conditions, they can develop into tissue or organ specific cells with unique functions. Stem cells, in organs such as the gut or in bone marrow, are capable of regularly dividing and repairing or replacing damaged, worn out cells (U.S. Department

In a developing embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult

Hemoglobin is the main part of the red blood cells, and it’s what helps bind the the oxygen to the blood. If your blood cells or hemoglobin isn’t normal, then your body cells will not get enough oxygen like they should. They’re are also multiple types of Anemia, such as Sickle cell Anemia. Sickle cell is one that only affects african Americans. Iron deficiency is

The million dollar question is “What is hereditary spherocytosis and is there a cure?” Hereditary spherocytosis is a disorder in the membrane of a red blood cell that causes the red blood cell to be shaped like spheres, instead of flat discs (Wint Carmella).
