MICROANATOMY

Detailed explanation-1: -Small lymphatic vessels join to form larger tributaries, called lymphatic trunks, which drain large regions. Lymphatic trunks merge until the lymph enters the two lymphatic ducts. The right lymphatic duct drains lymph from the upper right quadrant of the body. The thoracic duct drains all the rest.

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 collects most of the lymph in the body other than from the right thorax, arm, head, and neck. These are drained by the right lymphatic duct.
