Final answer:
The left upper, left lower, and right lower quadrants of the body, along with the left side of the head, thorax, and 2. left upper limb, drain into the left lymphatic system via the thoracic duct.
Step-by-step explanation:
The quadrants of the body that drain into the left lymphatic system, specifically via the thoracic duct, are the left upper quadrant, the left lower quadrant, the right lower quadrant, and the left side of the head, thorax, and left upper limb. The right upper quadrant of the body, including the right side of the head, thorax, and right upper limb, drains into the right lymphatic duct, which empties into the right subclavian vein. This drainage pattern demonstrates the asymmetry in the body’s lymphatic drainage system, with the right lymphatic duct serving a smaller portion of the body compared to the thoracic duct.
The left lymph is fed by the left upper quadrant and the left lower quadrant of the body. The lymphatic system is responsible for draining fluid and waste products from tissues, and it plays a critical role in immune function. On the left side of the body, lymph fluid from the remaining portions of the body enters the bloodstream through the larger thoracic duct, which drains into the left subclavian vein. This includes lymph from the left upper quadrant and the left lower quadrant.
