BLOOD TYPES One of the most important things in human biology and one that is relevant to all human beings is blood. Blood is divided into types, and although these blood types are not so much an issue in diagnosis of...read more
There are actually 29 different human blood type groups. The groups are determined by the protein found on the surface of the blood cell. Some of these protein antigens can cause serious problems in blood transfusions beca...read more
Unfortunately, our world is not as safe as most people would like it to be. Although it may not be best to imagine that danger lurks around every corner, it is important to recognize the reasonable (and probable) risks in...read more

Human blood is grouped into four main categories, A, B, AB, and O. Each letter symbolizes a different antigen or protein found on the surface of red blood cells. For example blood group B will have the antigen known as th...read more
There are four types of blood in the ABO system: A, B, AB, and O. Your blood type is determined by one gene from your mother and one from your father that combine to establish your blood type. These two genes determine you...read more
Understanding the difference between the blood types can be of major importance for issues including, but not limited to: blood transfusions, cancer treatments, donating organs and even to giving birth. There are four ...read more
Unless you're a doctor, knowing about the different blood types may be pretty useless. However, it does help to know what you have and what can go with you. According to my Biology of Sex professor (yes, I took that cla...read more

Different blood types are relatively simple. The types are A, B, AB and O. If you mix A with B they will "clump" as viewed microscopically so you can see they are incompatible in the bloodstream. The "R" factor, discove...read more
Every day thousands of pints of blood are donated across the U.S. for the purpose of transfusion in surgeries where a loss of blood is expected as well as injuries that cause significant blood loss. Although this may se...read more

Three different types of alleles determine an individual's blood type: A, B, and O. Alleles are one of the many genetic information found in the chromosomes of our DNA and by extension, in our blood. Each one of us inh...read more

Blood type is defined by the antigens (proteins that are coded to stimulate an immune response when a foreign substance is found) located on the surface of the red blood cells. There are two different antigens available t...read more
