The body loses water and satas in sweat explain why drinking large volumes of plain water after excersicing may affect the salta balance in the body

Sodium plays a critical role in balancing components of the body, and a lack of this element can become lethal if a large enough deficit is established. Losing salt through sweat reduces the concentration of Sodium in the body; however, drinking plain water dilutes what is left to a much larger degree (the loss of salt is accompanied by a loss of water, which keeps the concentration of Sodium in the body relatively constant), and this dilution causes consequences.

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.
