Today (Friday), I would like you to use the computer to view various animations and tutorials on urine formation. Try to understand the various processes involved and learn the names of the parts of the nephron. Here are some good animations and tutorials:
Animation 1
Animation 2
Animation 3
Also try searching youtube.com for other videos on urine formation and nephrons....there's lots!

Have a nice weekend. Be sure to keep up with textbook reading and homework questions....only 6 weeks left!
