Dr. Fong was a quest speaker for Mr. Olson's Biology class. Dr. Fong explained to the class about the functions and parts of the eye. She told us that the eye is very complex, that even Mr. Charles Darwin was stuck on how the eye had evolved. Dr. Fong also told the class that, looking at the eye, and its veins and arteries, a expert can tell if the person has high blood pressure, if the person was blond hair, young or old, if a person had diabetes, and even high cholesterol. Another interesting fact is that no one has the same Retina as you. Not even twins have the same Retina. When dissecting the sheep eye, the Retina was a opaque color, and Dr. Fong pointed out that, the older the eye, the more of an opaque color. A younger is clearer then the older eye. Dr. Fong was a great presenter, even though I didn't know much, if not anything about the eye before, Dr. Fong explained the basics and the functions of the eye clearly. She explained the "hard to understand" terms in simple terms, so that everyone can understand, which think really help the class to listen to. I really enjoyed the guest speaker, and I am now looking forward to learn more about the eye!
