Question

when some bacterial diseases enter the body, what specifically do the bacteria do that make them harmful to the body? they make the organs swell until they are unable to perform their proper function. they produce harmful chemicals in or around cells. they cause the immune system to stop working. they slow down the flow of blood.

Explanation:

Pathogenic bacteria that cause disease often secrete or produce toxic (harmful) chemicals called toxins, which damage host cells or interfere with normal bodily functions. The other options are not the specific, direct mechanism of most bacterial pathogens: organ swelling is a secondary immune response, bacteria do not directly stop the immune system entirely, and slowing blood flow is not a primary harmful action of bacteria.

Answer:

They produce harmful chemicals in or around cells.
