GENERAL HISTOLOGY

Detailed explanation-1: -The thoracic duct conveys the lymph from the entire body back to the venous circulation, except lymph from the right part of the head, neck and heart, right upper limb, parts of the left and right lung and part of the convex surface of the liver.

Detailed explanation-2: -Lymphatics are a network of endothelial tubes that merge to form two large systems that enter the veins. Lymph from the right side of the head, right trunk, and right arm drains into the right lymphatic duct. Lymph from the remainder of the body drains into the thoracic duct, which empties into the thoracic vena cava.

Detailed explanation-3: -The thoracic duct is the main lymphatic vessel for the return of chyle/lymph to the systemic venous system. It drains lymph from both lower limbs, abdomen (except the convex area of the liver), left hemithorax, left upper limb and left side of face and neck.

Detailed explanation-4: -the thoracic duct: It begins near the lower part of the spine and collects lymph from the pelvis, abdomen, and lower chest. The thoracic duct runs up through the chest and empties into the blood through a large vein near the left side of the neck.
