GENERAL HISTOLOGY

Detailed explanation-1: -The major lymphatic vessels are: 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.

Detailed explanation-2: -The lower extremities, left upper extremity, left head, left hemithorax, and subdiaphragmatic organs drain into the cisterna chyli and transit through the thoracic duct emptying into the left venous angle, near the junction of the left internal jugular and subclavian veins.

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.
