Welcome back. Here's our next question. It says the human body regulates the ph levels of several body parts, including the vagina. Why is it important to maintain its slightly acidic ph? So let's work through our answer choices here, Choice A. Says to ensure fertility. Well the ph of the vagina does not have anything to do with fertility. Um So that would be not be our answer here, Choice B says to protect the ovum inside the reproductive system. Um That's not our answer here. The album is back in the ovaries and not near the vagina choice C says to prevent the growth of harmful yeast and bacteria. That is our answer here. That slightly acidic ph discourages the growth of yeast and bacteria that cause illnesses. And then finally, Choice D to stimulate the production of estrogen. The vaginal ph doesn't have any effect on the production of estrogen. So that's not our answer here. So again, why is it important to maintain the slightly acidic ph of the vagina choice C to prevent the growth of harmful yeast and bacteria. See you in the next video
