Final answer:
The large intestine harbors beneficial bacteria that play a significant role in our health, including the production of essential vitamins like vitamin B12 and K.
Step-by-step explanation:
The statement that the bacteria in the large intestine feed on the material passing through and make certain vitamins for the body is TRUE. Our large intestine hosts trillions of bacteria which play crucial roles in our health. Among their various functions, these bacteria are responsible for producing important vitamins such as vitamin B12 and vitamin K. They also aid in breaking down dietary fibers and some starches and sugars that our bodies cannot digest on their own. Additionally, these bacterial communities contribute to our immune system by controlling the growth of harmful bacteria and stimulating the production of protective antibodies.
