Second graders in Mrs. Shelly Hendricks’ class began the year studying about the human body.

On Friday, they got a visit from Dr. Mark Hendricks, a local critical care pulmonologist, who gave a demonstration about the lungs and answered a lot of questions. He also happens to be Shelly’s husband.

“I think the response was good,” Shelly said of the visit. “They really liked the model of the lungs he brought and they asked a lot of interesting questions.”
