Question

Immune system is made up of

• A. Humoral system
• B. Humoral and fibrous systems
• C. Humoral and cell mediated systems
• D. Antigen induced antibodies

Answer 1

The correct option is C Humoral and cell mediated systems

• The immune system is a host defence system comprising many biological structures and processes within an organism that protects against disease. The immune system can be classified into subsystems such as the innate immune system and the adaptive immune system, or humoral immunity and cell-mediated immunity.
  
• Humoral immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides.
  
• Cell-mediated immunity is an immune response that does not involve antibodies, but rather involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.
  

So, the correct answer is 'Humoral and cell-mediated systems'.
