Ramya is studying one interesting organ of the body, its size of about a clenched fist. It is the body's engine room, responsible for pumping life-sustaining blood via a 60,000 mile-long network of vessels. In vertebrates, this organ can be classified based on the number of chambers present. For instance, most fish have two chambers, reptiles and amphibians have three chambers. Avian and mammalian consist of four chambers. In humans, it is made up of four chambers, two uppers, and two lowers. Ramya wants to know more about its functioning. Her teacher explains its structure and how it works. She also prepares a list of questions to confirm the understanding of Ramya regarding this organ.
