Mrs. Tretow's Health 9 students welcomed Dr. Angelie Singh, a resident at UW Family Medicine, into their class today. This year, they have discussed how their choices impact their health. Dr. Singh talked with the students and was able to show the students the impact their choices have on their organs. She had examples of a smoker's lung, liver, heart, and brain, as well as a spleen and spinal cord. This lesson was the culmination of many of the class's discussions this year.
