Human organs are specialized structures in the body that perform specific functions essential for survival. For example, the heart pumps blood, delivering oxygen and nutrients to cells, while the lungs allow us to breathe in oxygen and expel carbon dioxide. Each organ plays a vital role in maintaining our overall health and well-being. The liver processes nutrients and detoxifies harmful substances, while the kidneys filter waste from the blood and regulate fluid balance. Together, these organs work in harmony, forming complex systems that support life. Understanding how these organs function helps us appreciate the intricacies of the human body.
