Dr. Neena comes in to teach us about the human body. She taught us about the brain, the heart, and the digestive system. Her previous visit was when she taught us about the digestive system. She taught us about the esophagus, the stomach, the liver, the small intestine, the large intestine, and the anus. The brain sends messages to the spinal cord back and forth. And last but not least, the heart. The heart pumps blood through the body and has 4 chambers. The right ventricle, the left ventricle, the right atrium, and the left atrium.
