Study the definition.

consists of different organs that work together to carry out major body functions

Which correctly matches the definition?

lungs

respiratory system

blood vessels

blood cells

I would say it is respiratory system because none of the others are systems they are just single organs so that contradicts the answer

Plz mark as brainliest!

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

Hahaha good one. you ? & oop
