The Heart and Lungs
Students commonly struggle to envision the structure and function of the heart and lungs, particularly when it comes to the situation in a developing baby. This multitouch book was created to help students understand the anatomy of the heart and lungs, what occurs in each organ, and how they work together to keep the body functioning. The last part of the book was designed to help students understand what happens to the baby’s heart before and after birth.
Unable to interact with images in iPhone
I am unable to interact with your images in “The heart and lungs”; swiping on images like 2.2 does not reveal intended detail. This is on my iPhone 7+ running iOS 11.4.1. I must admit this is the latest iOS update; which might explain your interaction working on my iPad running 11.4.
