Ventral
The term "ventral" refers to the underside or belly side of an organism. In anatomy, it is used to describe structures that are located toward the front or lower part of the body. For example, in humans, the abdomen is considered ventral, while the back is referred to as dorsal.
In animals, the ventral side can vary in appearance and function. For instance, in fish, the ventral fin is located on the underside and helps with stability and movement. Understanding the ventral aspect is important in fields like biology and medicine, as it aids in the study of anatomy and physiology.
