In order to make my biology studies far more interesting, I decided to Google up blood group.
First of all, lets see what determines our blood group: I found a really easy explanation..
What is blood made up of?
- Plasma, the liquid part of blood, makes up about 60% of the blood's volume. Plasma is mainly made from water, but contains many different proteins and other chemicals such as hormones, antibodies, enzymes, glucose, fat particles, salts, etc.
- Blood cells, which can be seen under a microscope, make up about 40% of the blood's volume. Blood cells are made in the bone marrow by blood 'stem' cells. Blood cells are divided into three main types:
- Red cells (erythrocytes). These make blood a red colour. One drop of blood contains about five million red cells. A constant new supply of red blood cells is needed to replace old cells that break down. Millions are released into the bloodstream from the bone marrow each day. Red cells contain a chemical called haemoglobin. This binds to oxygen, and takes oxygen from the lungs to all parts of the body.
- White cells (leucocytes). There are different types such as neutrophils (polymorphs), lymphocytes, eosinophils, monocytes, basophils. They are a part of the immune system and are mainly involved in combating infection.
- Platelets. These are tiny and help the blood to clot if we cut ourselves.
What is a blood group?
Red blood cells have certain proteins on their surface, called antigens. Also, your plasma contains antibodies which will attack certain antigens if they are present. There are various types of red blood cell antigens - the ABO and rhesus types are the most important.
These were the first type discovered.
- If you have type A antigens on the surface of your red blood cells, you also have anti-B antibodies in your plasma.
- If you have type B antigens on the surface of your red blood cells, you also have anti-A antibodies in your plasma.
- If you have type A and type B antigens on the surface of your red blood cells, you do not have antibodies to A or B antigens in your plasma.
- If you have neither type A nor type B antigens on the surface of your red blood cells, you have anti-A and anti-B antibodies in your plasma.
Most people are 'rhesus positive' as they have rhesus antigens on their red blood cells. But, about 3 in 20 people do not have rhesus antibodies and are said to be 'rhesus negative'.
Blood group names
Your blood group depends on which antigens occur on the surface of your red blood cells. Your genetic make-up which you inherit from your parents determines which antigens occur on your red blood cells. Because of this fact a blood group test is sometimes used to help settle disputes about who is the father of a child. Your blood group is said to be:
- A+ (A positive) if you have A and rhesus antigens.
- A– (A negative) if you have A antigens, but not rhesus antigens.
- B+ (B positive) if you have B and rhesus antigens.
- B– (B negative) if you have B antigens, but not rhesus antigens.
- AB+ (AB positive) if you have A, B and rhesus antigens.
- AB– (AB negative) if you have A and B antigens, but not rhesus antigens.
- O+ (O positive) if you have neither A nor B antigens, but you have rhesus antigens.
- O– (O negative) if you have do not have A, B or rhesus antigens
Now, I'm sure most of you already are aware of the fact that you're supposed to be eating according to your blood group. If you want to lose or gain weight that are certain foods you should consume/avoid.
What you probably didn't know is that apparently your blood group has something to do with you personality..Check the links, they include the diet stuff as well

So tell me, any 'That is so me!' ?
