FUNCTIONAL ANATOMY OF THE LYMPHATIC AND IMMUNE SYSTEMS

3. LYMPHATIC VESSELS AND NODES OF THE ABDOMINAL CAVITY

Lymph from the upper PARTS OF THE anterior abdominal wall drains into the axillary nodes, and from the lower parts, into the inguinal nodes.

In the Abdominal cavity, there are parietal nodes located around the aorta and INFERIOR VENA CAVA, and visceral nodes situated along the Branches of the celiac trunk and mesenteric Arteries, within the mesentery of the small and large intestines.

The Small Intestine features a specialized system of Lymphatic vessels known as lacteals, so named because they transport absorbed fat, which gives the lymph the appearance of a milky emulsion (chyle).

From the mesenteric nodes, lymph flows to the lumbar nodes, and from there into the left lumbar trunk and, ultimately, into the Thoracic duct.

Lymph drainage from the Large Intestine occurs into the ileocecal, right and left colic, medial, and inferior mesenteric Lymph Nodes (Fig. 5.48).
