Omentum: Learn about the omentum

Learn about the omentum, including its structure and function, plus why it is important in metastatic malignancies, such as ovarian cancer. The omentum appears to be a primary site of B-lymphocyte development [19, 20]. In experimental animals, the omentum is a source of unique B-lymphocytes that demonstrate specific surface markers. These B-lymphocytes are predominantly CD5+ (Lyl+), and are common in not only the omentum but also the peritoneum. Understanding Omentum in Human Anatomy The omentum is a complex and multifaceted structure within the human body, playing a crucial role in various physiological processes and pathological conditions. This article aims to provide a comprehensive overview of the omentum, exploring its anatomy, functions, and clinical significance. What is Omentum?
