Parts of the bloodBlood is the fluid circulating in the body that carries nutrients and oxygen, removes waste products and fights infection.
• Red Blood Cells
• Plasma
• White Cells
• Platelets
Red blood cellsRed blood cells carry oxygen to the body’s organs and tissues.The inside of the red blood cell is filled with the protein haemoglobin.
PlasmaBlood cells float in a straw-coloured liquid called plasma
Plasma consist of water, waste, and hormones.
White blood cellsWhite blood cells attack invading
microbes that cause disease
They do this in two ways:1. One type of white blood cell produces
chemicals called antibodies. These antibodies lock on to proteins
called antigens on the surface of the microbes.
2. Another type of white blood cell digests any microbes the antibodies lock on to.
Platelets
Platelets are• bits of cell broken off
large cells
They • help blood to clot • and stop bleeding at cuts.
If wound is too large, your blood doesn’t clot. You need a blood
transfusion• Blood transfusion-transfer of blood from one person to next
• Replaces lost blood
• Regularly treat serious blood diseases.
Blood groups• There are four blood groups – A, B, AB and O• Your parents’ blood groups affect what group you
belong to. One gene from mother one gene from father• Your genes cause proteins to exist on surface of all
red blood cells
Clumping Proteins
• These proteins recognize foreign blood and then clump– Ex: if you have blood type A, your blood
will clump when mixed with B
• Clumping= failed transfusion. Clogs capillaries and leads to death
