Dr. Woody Visits 4H!

     We have been studying the human body in science.  We’ve learned some fascinating facts about several body systems, including the skeletal, muscular, circulatory, and respiratory systems. 
     Recently, Dr. Ray Woody, retired veterinarian, visited our class and spoke to us about the cardiovascular system.  He brought along a deer heart and dissected it to show each of the 4 chambers of the heart.  Our students learned about the left and right ventricles, the left and right atrium, the aorta, and how the blood needs to go to the lungs from the heart to get oxygen. He even drew a picture of the heart on the board and explained about the valves of the heart. Fourth graders were able to see first hand the thickness of the left ventricle, how the aorta takes the blood to the rest of the body, and how amazing and important the heart is in our bodies.  We thank Dr. Woody for coming in to our class and teaching us all about the heart.
