the third line of defence work as a Primary Responce and a Secondary Responce the Primary Responce occurs when first a pathagen enter the body and secondly lymphocytes (b-cell) produce antibodies and finally antibodies have a speific shape which bind to antigens on surface of pathagen and then the dead pathagen is digested is eaten by phagocytes The Second Responce is the vaccination that contain live pathagen treated to make them harmless and it contain harmless fragment of the pathagen and dead phagen or toxins produced by pathagen and while vaccine is given we will gel active immunity because that vaccine will produce antibodies for ever

Is circulatory system the last body and most complicated line of defense against infection?

No, the circulatory system is not the last line of defense against infection. The immune system plays the primary role in defending the body against infections. The circulatory system helps in distributing immune cells and antibodies throughout the body to fight off infections, but it is not the final line of defense.


What system is the body's first line of defense?

The body's first line of defense is the innate immune system, which includes physical and chemical barriers like skin, mucous membranes, and stomach acid that help prevent pathogens from entering the body. If pathogens breach these barriers, the immune system responds with inflammation and activates other immune cells to fight off the infection.


Are phagocytes part of the second line of defense against microorganisms?

Yes, phagocytes are part of the second line of defense in the immune system. They help to engulf and destroy pathogens that have breached the first line of defense such as the skin and mucous membranes. Examples of phagocytes include macrophages and neutrophils.


The skin and mucous membranes are examples of?

The skin and mucous membranes are examples of physical barriers that serve as the first line of defense for the immune system. They help to prevent pathogens from entering the body and causing infection.


What is the main line of defense?

The main line of defense in the human body is the immune system, which helps to protect against pathogens such as bacteria, viruses, and parasites. This includes physical barriers like the skin, as well as specialized cells and proteins that work together to identify and neutralize harmful invaders.

Is memory cells part of third line of body defence?

Yes, memory cells are part of the adaptive immune response, which is considered the third line of defense in the immune system. Memory cells are responsible for remembering previous encounters with specific pathogens and mounting a quicker and more efficient immune response upon re-exposure.
