Exploration of lymphatic structures of gastrointestinal tract

Lymph nodes and vessels of lesser omentum and cardioesophagal junction

Lymphatics which are related to branches of the left gastric artery are visible in this close-up view of the cardiac part of the stomach. Some filaments of the left gastric plexus of nerves and of the anterior vagal trunk (4) are intermingled with the lymphatic vessels. Blood vessels and nerves in this area are shown in more detail in view 142-1, after the removal of the lymphatic tissue.

3. Cardiac part of stomach (pointer indicates cardioesophageal junction)
4. Anterior vagal trunk
5. Esophageal branch of left gastric artery
6. Left gastric artery
7. Lesser omentum
