How is Urea Formed and Excreted?
One of my students asked me recently if ammonia was a breakdown product of bile.
I was very confused.
Then I realized that she had been listening to a lecture on the various roles of the liver and had gotten a few things mixed up.
What she really meant was, "What's going on with ammonia, how is it related to the liver, and why is it a bad thing?"
Here's my answer:
Voilà. Hope that helps to clear things up and answer the question, "How is urea formed?".
One thing I didn't mention in the video is that a very small amount of ammonia (actually ammonium) travels in the blood under normal conditions.
That's it for now. Let me know if you've got any questions.
