What is the fundus of a hollow organ?

The fundus of a hollow organ is defined as the part that is farthest from the opening of that organ. This anatomical term is commonly used in reference to various hollow structures in the body, such as the stomach, where the fundus is the uppermost portion that lies above the opening of the esophagus into the stomach. Understanding the term "fundus" is crucial for medical professionals as it helps in identifying specific areas of organs for diagnosis or treatment.

For example, in the case of the stomach, knowing that the fundus is positioned farthest from the pylorus (the opening to the small intestine) allows veterinary professionals to precisely locate issues related to gastric function or pathology. This understanding of organ anatomy is critical in veterinary medicine, where various species may have different organ shapes and functions.
