The Positive Impacts of Blood Donation in Saving Millions Of People

Powerful Impacts of Blood Donation Every year, millions of people are dying due to a deficiency of healthy blood cells. They are suffering from a variety of illnesses – sickle cell anemia, cancer, hemophilia (just to name a few) – and are in need of blood donations that could save their lives. However, such a small percentage of Americans choose to take the time to go to a blood drive once every 56 days and take an hour to answer some questions and get a quick pinch of a needle. Why? To ensure the safety of donors and recipients, there are a set of requirements for eligibility to donate blood. Typically, the donor must be in good health, be at least 17 years old age (although in some states 16-year-olds can donate blood with parental consent), and weigh at least 1...

4 major types of blood: A, B, AB, and O

There are 4 major types of blood A, B, AB, and O. What blood you have depends on what antigen is on red cells and what antibody in the plasma; more on that later. Blood type is hereditary and which one you have, depends on your parents. If both parents have A blood type, the child will most likely have an A blood type as well. Similarly, B and B-type parents will produce offspring with B-type blood. However, if one parent is A-type and the other B-type, the child will be AB-type. Okay that’s all quite simple, but things get trickier when we introduce the O blood type. A and B blood types are dominant genes, or “alleles” to be more precise. Whereas the allele responsible for O blood type in recessive. This means if one parent has an O blood type and the other parent has ...

Sickle cell disease -one of the most common inherited blood disorders

Genetic disorders are (usually) rare disease not caused by viruses or other pathogens, but rather from human genetics itself. These disorders are sometimes inherited, like cystic fibrosis, and other times caused by mutations, like Down’s syndrome. Sickle cell is a (inherited) genetic disorder and causes blood cells to shaped like sickles (hence the name), or crescent-shaped blades, to form and due to this, blood cells can’t carry oxygen as well as normal blood cells. Sickle cell disease is caused by mutations due to the deletion of parts of chromosome number 11. This trait is recessive and can be passed on from parent to child. Although the sickle cell disease is harmful mutation due to health complications such as anemia, damage to the spleen, etc., it is also a bene...

The ABO blood group system

In the ABO blood group system, the red blood cells in humans have molecular differences from individual to individual. The differences are systematic and can be characterized according to a system of four different hereditary types; A, B, AB and O. These types together form the blood grouping system, ABO. The differences in these four hereditary blood types are due to the four types having different variants or combinations of antigens. In the ABO group the antigens are carbohydrate chains in the membrane on the surface of the red blood cells. Each human individual has antibodies to the variants that it does not have. The carbohydrate chains are available in two main groups, A and B. Humans with blood type A, have type A carbohydrate chains. Humans with blood type B h...

Blood doping and athletes

It is illegal for athletes to take steroids or any other type of drugs, so they are relying on blood doping. Right before an event, an athlete will blood dope. By doing that they take a substance to enhance the red blood blood cell count. As the erythrocytes go up the oxygen is easily transported to the muscle making the performance of the athlete better. The main type of blood doping uses are synthetic oxygen carriers, blood transfusions, and erythropoietin (EPO). Purified proteins or chemicals having the ability to carry oxygen are known as synthetic oxygen carriers. Some examples of them are haemoglobin based oxygen carriers (HBOCs) or perfluorocarbons (PFCs). Doing this brings the risk of cardiovascular disease. Synthetic oxygen carriers are mainly used in emergency...

Blood circulation in the human body

Although the heart plays one of the biggest roles in the circulatory system, the rest of the system is also very important as it is what transports blood to and from the heart to keep the body alive. Blood is transported throughout the body by blood vessels. Blood vessels are complex structures but can be simplified quite significantly. The two main components of blood vessels are the arteries and the veins. Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood to the heart. Other blood vessels found in the circulatory system are arterioles and venules. Arterioles are blood vessel that branch off arteries and lead to capillaries. Venules are similar to arterioles but branch off veins and also lead to capillaries. Finally, capillaries ...
