In my science class with my teacher, Karen, we were learning about the human body. The human body is too complex so we need to learn about it step by step otherwise, we will get confused. So we started learning about one of the systems in our body which is called the circulatory system. Basically, we learn how our heart works and the blood. Everyone knows that when a person’s heart stops beating which means that he/she is no longer survive. Our heart has a significant job of pumping the blood (RBC) to our whole body. The reason that it’s important is because blood contains oxygen and nutrient that our cells need in order to function well. In the RBC, there are 250 million hemoglobin and each of those contain four iron that attracted to four oxygen. Is that amazing! It is important that everyone take care of their heart well especially don’t eat lots of food that contain too many lipids.
