In what context have you heard about immune system in your everyday life? I heard about immune system from various TV shows and from the Internet.

 

p. 167

1) Why do we need an immune system? We need ian immune system because it protects our organism from genetically heterogenous cells or substances that come from outside or form in our organism.

2) Nowadays we have many supplements (БАД) on the market. Can all they replace our immune system? Supplements can’t replace our immune system because they are used as an additional source of food and biologically active substances, to normalize and improve the functional state of organs and systems, reduce the risk of diseases and others. Supplements aren’t medicines.

4) Look at the picture and say if you know all parts of the immune system. Consult the dictionary if necessary. I know all parts of the immune system.

1) What is the immune system? What is the basic function of the immune system?

 It is an amazing protection mechanism. The immune system defends against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade the body.
