TODAY:

- diseases

Antigens:

• Antigens are like the passport of a cell. This how your body knows if a cell does or does not belong in your body.
  
• Antigens are proteins that sit on the cell wall/cell membrane of all cells in nature.

Antibodies:

• Your cells produce these to fit the antigens and so attack the pathogens. These are produced by the B-cells.
• stick to antigens
• make pathogens stick together
• stop reproduction 
• work as a gps

Phagocytes:

• The stupid soldiers
• They attack anything with foreign antigens.
• The also attack anything with antibodies attached
• They can track antibodies.

Lymphocytes:

• B-cells
  

     - stick the antibodies together

     - produce the antibodies

     - make memory cells

• T-Helper cells
  

     - identify enemies

     - activate B-cells

• T- Killers cells
  

    - if need be produce toxins to kill the pathogens the phagocytes can't kill

    - produce toxins to neutralise those of the pathogens

Diabetes:

• A person who is a diabetic cannot make the hormone insuline.
  
• Insuline is needed to change glucose into a chemical that is stored in the liver.

Heamophelia

• A heamopheliac does not produce platelets or fibrine.
• They can bleed to death from even the smallest wounds.

heart attack

• One or more bloodvessels around the heart muscle (coronary arteries) is blocked.
• Parts of the heart stop beating or start beating irregularly.

Stroke

• One or more bloodvessels to the brain are blocked.
• Parts of the brain get starved of Oxygen and can be damaged permanently.
•
