Blood Groups

Thirty-three major blood group systems (including the AB and Rh systems) were recognised by the International Society of Blood Transfusion (ISBT) in October 2012.^[1] In addition to the ABO antigens and Rhesus antigens, many other antigens are expressed on the red blood cell surface membrane. For example, an individual can be AB RhD positive, and at the same time M and N positive (MNS system), K positive (Kell system), and Le^a or Le^b positive (Lewis system). Many of the blood group systems were named after the patients in whom the corresponding antibodies were initially encountered.

Blood is composed of cells suspended in a liquid like substance. The liquid portion is the plasma. Suspended in the plasma are three types of cells:

• Red cells carry oxygen
• White cells fight infection
• Platelets stop bleeding in injuries

The most common type of grouping is the ABO grouping. The varieties of glycoprotein coating on red blood cells divides blood into four groups:

• A (A oligosaccharide is present)
• B (B oligosaccharide is present)
• AB (A and B oligosaccharides are present)
• O (neither A nor B, only their precursor H oligosaccharide present)

There are subtypes under this grouping (listed as A1, A2, A1B or A2B…) some of which are quite rare. Apart from this there is a protein which plays an important part in the grouping of blood. This is called the Rh factor. If this is present, the particular blood type is called positive. If it is absent, it is called negative. Thus we have the following broad categories:^[3]

• A1 Negative (A1 -ve)
• A1 Positive (A1 +ve)
• A1B Negative (A1B -ve)
• A1B Positive (A1B +ve)
• A2 Negative (A2 -ve)
• A2 Positive (A2 +ve)
• A2B Negative (A2B -ve)
• A2B Positive (A2B +ve)
• B Negative (B -ve)
• B Positive (B +ve)
• B1 Positive (B1 +ve)
• O Negative (O -ve)
• O Positive (O +ve)

Giraffe facts found from internet

The giraffe is the tallest mammal in the world, with even new-born babies being taller than most humans.

Baby Giraffes can stand within half an hour and after only 10 hours can actually run alongside their family.

Giraffes spend most of their lives standing up; they even sleep and give birth standing up.

Giraffes only spend between 10 minutes and two hours asleep per day. They have one of the shortest sleep requirements of any mammal.

Young giraffes hang out in nursery groups until they are around 5 months old, resting and playing together while their mothers forage in the distance.

Giraffes are sociable, peaceful animals which rarely fight. Males do perform a behaviour called ‘necking’ where they will hit necks; however these encounters rarely last more than a couple of minutes and seldom result in injury.

Just like snowflakes and human fingerprints, no two giraffes have the same spot pattern.

Even giraffes tongues are huge. They are up to 45cm long and are specially adapted to allow giraffes to forage on trees that other animals would avoid, such as acacias which are very thorny.

Life span in the wild: Around 25 years

Size: 4.3-5.8m high

Weight: Around 800 kg for females and 1250 kg for adults
