Join Corpy on an adventure to the liver! Corpy is a red blood cell with a very important job – delivering oxygen and removing carbon dioxide inside the human body. With the help of his friend Lucy, a white blood cell, Corpy makes his first trip to the Liver! There, he learns about the specific functions of this vital organ. He meets many of the cells that make up the liver including Endy, an endothelial cell, and Cholly, a cholangiocyte who makes bile. Children (and parents!) get the chance to learn about human anatomy in a fun and engaging way. Written by board-certified cardiologist Dr. Romel C. Wrenn and his daughter Danielle C. Wrenn, Corpy Visits the liver is an exciting and educational story for children 6 years and up.
