APPLIED RADIOLOGICAL ANATOMY

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 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-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.
