Answer:
The correct answer is it causes immediate pathogen lysis.
Explanation:
The complement system is a part of innate immune system which is called first line of defense mechanism of our body.
complement system along with various proteins and enzymes stimulate the phagocytic cells to attack the plasma membrane of foreign pathogen,Which ultimately result in the lysis of foreign pathogen by phagocytosis mechanism.
Answer:
The complement system of defense is composed of proteins that are always present in the blood.
(A) It causes immediate pathogen lysis.
This statement describes the importance of this system in early pathogen defense.
Explanation:
The "complement system" is the protein series found in blood plasma. They are not a part of induced immune response which is early.
"Barrier defenses" are part of defense mechanism of the body. It is like body continuously protects itself against the pathogens.
The complement system is very important because it destroys the pathogens and eliminate the infection. The phagocytic cells and antibodies help in clearing the damaged cells present in an organism with this way.
