Organs are specialized structures in our bodies that perform specific functions essential for survival. For example, the heart pumps blood, delivering oxygen and nutrients to all parts of the body. Other organs, like the lungs, help us breathe by taking in oxygen and releasing carbon dioxide. Each organ works together with others to keep our body functioning properly. In addition to human organs, many animals have organs that serve similar purposes. For instance, the liver helps filter toxins from the blood in both humans and animals. Understanding how organs work can help us appreciate the complexity of life and the importance of taking care of our bodies.
