Answer:
Thoracic duct.
Explanation:
Thoracic duct is the larger of the two lymph ducts of the lymphatic system. It is also known as the left lymphatic duct, alimentary duct, chyliferous
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. A large portion of the body's lymph is collected by this duct and then drained into the bloodstream near the brachiocephalic vein between the internal jugular and the left subclavian veins.
The typical length of this duct in an adult averages between 38 and 45cm, while the diameter is about 5 to 7 mm. It originates from the second lumbar vertebra level and goes to the neck's root. The duct arises from the combination of the left and right lumbar trunks and the intestinal trunk in the abdomen.
It transports up to four liters of lymphatic fluid each day. This process is primarily caused by the breathing action and is assisted by the smooth muscle of the duct.

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation. The next generation will have the things they will need to survive and the longer the generation goes the more fetchers they will have.
