Viscera refers to the internal organs of the body, particularly those within the abdominal cavity. These organs include the stomach, liver, intestines, and kidneys, among others. Viscera play crucial roles in digestion, metabolism, and waste elimination, contributing to overall bodily function. In medical contexts, the term "visceral" can also describe sensations or emotions that are deeply felt, often linked to gut reactions. Understanding the viscera is important in fields like anatomy, physiology, and medicine, as they are vital for maintaining health and diagnosing diseases.
