Hello, my dear young biologist! I know that you are confused of how our body is made. What are inside our body and if we study it closely what’s inside? As a living organism, we are made up of different organ systems that work together to make them function. We need them to function well for us to survive. In order to maintain its function, we need to provide its basic needs. When we eat healthy foods our digestive system breaks them into simple substances which eventually are transported throughout the body by the circulatory system. But what is responsible in transporting these nutrients? Is it the circulatory system alone? Are these systems made up of smaller parts? Absolutely yes, it is made up of different organs to make it work as a system. Just like the mouth, esophagus, stomach and intestines are grouped together to form the digestive system. The arteries, heart and veins are also grouped together to form the circulatory system.
