Hey, everyone. Let's take a look at this question together. The following include the different parts of the urinary system, except which is it answer choice. A, the urethra, answer choice B, the anus answer choice C the bladder or answer choice D the kidneys, let's work this problem out together to try to figure out which of the following answer choices is not included in the parts of the urinary system. So in order to solve this question, we have to recall the different parts of the urinary system to determine which of the following is not included. And we can recall that the urinary system consists of the kidneys, the ureters, the urinary bladder and the urethra. So looking at our answer choices, we see we have the kidneys, we have the bladder and we have the urethra. However, answer choice B which says the anus, we know that the anus is not part of the urinary system and instead is part of the digestive system. So answer choice B is the correct answer as it is not included in the urinary system. And all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.

You order blood work and find that the concentration of this medication in his plasma is much higher than normal. How does his decreased GFR explain the elevated level of medication in his plasma?
