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. Trunks continue to anastomose and enlarge, forming embryonic right and left thoracic ducts.

Detailed explanation-2: -The right lymphatic duct drains most of the right upper quadrant of the body, including the right upper trunk, right upper extremity, and right head and neck. The right lymphatic trunk is a visible channel in the right cervical region just anterior to the anterior scalene muscle.

Detailed explanation-3: -The thoracic duct drains into to the left subclavian vein while the right duct drains into the right subclavian vein, both at the junction between the respective vein and the jugular vein. The two subclavian veins then merge into the vena cava, the large vein that brings deoxygenated blood to the heart.
