Blood type O – and complete information about it. Certainly you should know that there are four known types of blood groups, which are A, B, AB and O. Blood groups differ from one person to another according to the genetic genes that a person obtains from his parents. Blood groups were first classified in the first decade of the twentieth century by the Austrian physician Karl Landsteiner.
It is important for each of us to know his blood type because of the importance of determining the blood type in emergency situations or in cases of blood donation. Because blood matching is critical to avoid the negative effects and reactions that may occur in the event of a mismatch.
And blood – that sticky fluid that supplies the body with everything it needs – consists of red blood cells, white blood cells, platelets and blood plasma. And each of them plays an important role in the human body. Red blood cells are responsible for transporting oxygen and nutrients to all cells and parts of the body. While white blood cells play a key role in the formation of the body’s immune system, which fights infections that the body may be exposed to, such as infection with bacteria or viruses. And the platelets work to form blood clots in the event of a cut or scratch on the surface of the skin.
There are four main blood groups, depending on the presence or absence of antigens, or what are known as “antigens” that appear on red blood cells. There are two types of antigens that are present or not present on the surface of red blood cells, A and B.
Blood type A is characterized by the presence of A antigens on the surface of red blood cells. This is in addition to the presence of antibodies to B antigens.
While blood type B is characterized by the presence of B antigens on the surface of red blood cells, in addition to the presence of antibodies to A antigens.
People with blood type AB are characterized by the presence of both A and B antigens, and this group does not have any antibodies.
While type O blood is characterized by the presence of antibodies to A and B antigens, and the absence of any antigens on the surface of red blood cells.
In addition to these antigens, another factor that determines blood type is the Rh factor. It is either positive, Or negative,
Type O blood is considered a rather rare blood group. Where research indicates that 1 out of every 7 people carries the blood type O-. And blood donation centers in the United States of America indicate that the percentage of blood donors who carry type O blood – represent about 13% of all blood donors. While the percentage of donors who carry type O + blood is about 35% of the donors. Which shows that it is a rather small species.
A holder of blood type O- is known as a general donor, or what is known as “universal donor” because of his ability to donate blood to any other blood type, and this makes him one of the best types of blood groups that you can rely on for transfusion of blood for anyone who needs a blood transfusion. Transfusion
What foods are suitable for people with blood type O – ?
There are some studies that suggest that a certain diet may help maintain a person’s health. They also advise people with different blood types to avoid some types of food, which may lead to some health problems.
And some health experts confirm that people with blood type O – are more likely to suffer from heartburn, so it is better for them to avoid some foods that cause stomach ulcers . While its owners are advised to eat useful proteins such as fish, beef, and others.
They can also eat nuts to get healthy fats and proteins. In addition, they recommend eating various vegetables and fruits that improve digestion. It also reduces stomach and digestive problems.
As we mentioned, there are 4 different blood types, which are A, B, AB, and O. Depending on the Rh factor or “Rh factor”, we will get 8 different types. And the blood type O – is one of the best blood types in terms of the blood donation process.
People with type O blood can donate to all different blood types, even if they have a different Rh factor. Whereas, when a person with type O needs blood, he can only get it from a person of the same blood type.
Knowing the blood type is one of the most important things that a person must know. This is because of its importance in the process of transfusion or blood donation. If you have type O blood – you should know that you can transfuse blood to anyone who needs blood of any blood type.
