Ten interested Quizzes : Prizes for Correct Answers -Episode 2 (Human body related )

Quiz is my favorite. During schooling, we used to do a lot of quiz contests among ourselves in the class. I can proudly say that I was the winner of the maximum contest. Science, nature and animal world were more favorite subjects of my quiz contest. I knew a little less about sports. And I could not do much in geography and history. However, there were enviable skills in math and intelligence quizzes.
