'Having a healthy lifestyle and regular exercise will help your blood pressure stay at a normal range.' Awareness behind the numbers 'These two numbers together show your provider a picture of how well the blood and oxygen are moving through the heart and can even help predict possible health complications,' Hodges said. That is the pressure in your arteries between heartbeats. The second, or bottom, the number is diastolic. That's the amount of pressure inside your arteries when your heart muscle contracts. Hodges said the first, or top, the number represents systolic pressure. 'Blood pressure numbers represent your heart's health,' said Hanna Hodges, BS, NCMA, MA/MOA Program Director at Concorde's campus in San Antonio, Texas. It is also important to note that, in general, Rh-negative blood is given to Rh-negative patients, while Rh-positive blood or Rh-negative blood may be given to Rh-positive patients. However, they can only receive from other O donors. Group O is the universal donor, able to donate to all other groups.However, they can only donate to other AB recipients. Group AB is the universal recipient, able to receive blood from all groups.Group B can donate red blood cells to groups B and AB.Group A can donate red blood cells to groups A and AB.The list below explains which blood types are capable of cross-matching with other types. It probably goes without saying, but physicians must be extremely careful when finding compatible blood types for transfusions. BLOOD GROUP COMPATIBILITY AND UNIVERSAL DONORS/RECIPIENTS For example, this is why our blood is classified as A+ (A positive) or O- (O negative). In addition to the A and B antigens, a third antigen called the Rh factor can be present (+) or absent (-) and also contributes to blood type. Group O contains neither A nor B antigens on red blood cells but does contain both A and B antibodies in the plasma.Group AB contains both A and B antigens on red blood cells with neither A nor B antibodies in the plasma.

Group B contains only the B antigen on red blood cells with the A antibody in the plasma.Group A contains only the A antigen on red blood cells with the B antibody in the plasma.

It identifies four different common blood types that are determined by the presence or absence of certain antigens. This system is the most important blood group system used in human blood transfusion. In 19, Karl Landsteiner at the University of Vienna was attempting to uncover the cause of these failed transfusions and ended up discovering the common blood types we know today - a discovery that eventually earned him the Nobel Prize. If the blood of different groups mix (during transfusions or otherwise), these antigens can trigger a person's immune system to attack and reject the new 'invading' blood, causing sickness or even death. Each blood type or 'group' has a specific set of inherited antigenic substances, such as proteins, glycoproteins, carbohydrates, and glycolipids, which make it unique. We've all got blood running through our veins, and while it might look the same to the naked eye, it's actually different from person to person.
