Organs
An organ is a group of tissues that work together to perform specific functions in the body. These functions can be related to a particular system, such as the digestive system, respiratory system, or circulatory system. Each organ has a specific structure and function that allows it to contribute to the overall health and well-being of the organism.

There are several types of organs in the human body, each with its own unique function:
- Vital Organs: These are essential for survival and include the heart, lungs, liver, and brain.
