Question

The next time autumn leaves drift by Maddie's window, she may just let them lie. During the last week of September, city workers sprayed chemicals on the trees along the street in front of her house. In October, when the leaves from those trees began to fall, Maddie raked them up and stuffed them into several large garbage bags. The next day, her hands were red and itchy, and by the day after that, the itching had necome intense. In addition, Maddie's hands were covered with blisterlike lesions and so swollen that she could hardly move her fingers. Maddie suspected she was having an allergic reaction. Was she right? After reading about the lymphatic system and immunity in this chapter and connecting that information with what you learned about the peripheral circulation in chapter 21, explain the probable cause of Maddie's symptoms?
