Complement system of Human body 1

-

 Human body daily encounter numerous pathogens and foreign bodies. To cope up with its harmful effect our body has defence mechanism i.e. Immune system.To assist immune system there is complementary system in our body which serves as 2nd line of defence. This is basic definition of complementary system of human body. 

Complementary system consists of various protein primarily synthesised in liver and they are present in our blood stream in an inactivated form. As soon as our body encounter pathogens or foreign antigen they become active and start their function in series of steps. Complementary protein 1 further activates other protein in series of step which will be discussed in other blog and they develop a system which by following ways kills the foreign body (Antigen, Bacteria, Fungi etc.. )

1) By making pore in cell membrane of foreign body 

2) By activating Neutrophil  

3) By activating Mast cells which secrete histamine and other lysosomal products 


This was the basic information about complementary system of Human Body for more blogs Stay tuned.

Thank you for reading blog patiently.
