Question

what is the job of white blood cells? act as chemical messengers in the body attack germs that dont belong in the body regulate body temperature eliminate waste from the body

Explanation:

White blood cells are part of the immune system. Their main function is to defend the body against pathogens (germs like bacteria, viruses, etc.). Chemical messengers are typically hormones (e.g., insulin, adrenaline). Body temperature regulation is mainly through processes like sweating (evaporative cooling) and shivering (heat generation) involving the skin, hypothalamus, etc. Waste elimination is done by organs like the kidneys (filtering blood to produce urine), liver (processing toxins), and intestines (removing undigested food).

Answer:

Attack germs that don't belong in the body
