MICROANATOMY

Detailed explanation-1: -The thoracic duct develops from lymphatic trunks on either side of the aorta that anastomoses to form a channel from the jugular lymph sacs to the cisterna chyli.

Detailed explanation-2: -The thoracic duct is the largest lymphatic vessel within the human body, and plays a key role in the lymphatic system. It is also called the left lymphatic duct or the alimentary duct.

Detailed explanation-3: -Some lymph nodes are clustered under the skin, particularly in the neck, armpits, and groin. Other lymph nodes are deep within the body, for example inside the abdomen. The lymphatic vessels drain into collecting ducts, which empty their contents into the two subclavian veins, located under the collarbones.
