Natural acquired active immunity: Artificial acquired active immunity:

 

Natural acquired passive immunity: Artificial acquired passive immunity:

 

Innate immunity:  

Weakened germs given so the body can create resistance to a certain disease. (e.g. Measles, Mumps and Rubella vaccine)

 

When you become immune by actually having the infection and the body is able to recognise the same infection and kill it without you experiencing any symptoms. (e.g. chicken pox)

When antibodies are passed from mother to baby during pregnancy. (Not an everlasting immunity)

 

Not a specific immunity, such as the skin, tears, stomach acid.

Short-term immunization by and injection of antibodies into the system, which will not give lasting immunity (e.g. Tetanus)

Bacteria can get through the barriers and enter the body through cuts & scratches or in the food

we eat and the air we breathe.

Bacteria reproduce quickly, threaten cells and can block vital organs.

If the bacterial invasion can't be stopped, more phagocytes from other

parts of the body travel in the blood vessels to

help.

B cells multiply into billions of cells, which bind to the invader and destroy it. T Cells identify and destroy any human cells which may

have died or changed or those which it recognises as non-human.

Some B & T cells produced live on after the first attack and help the body fight against a second attack should it occur. You are therefore immune to these bacteria

Skin is waterproof and airtight; it excretes oil, which contains chemicals. Tears wash away micro organisms, hairs in the nose filter air and coughing and sneezing expel micro organisms. Stomach digestive juices can kill some organisms that enter through the mouth.

Phagocytes are a group of white blood cells found in

bone marrow that can move and ingest invaders until they themselves burst and die.

B cells are one kind of lymphocyte, (white blood cells) covered with chemical feelers called antibodies, which seek out and investigate invaders.
