Which of the following statements is TRUE? A.
The thoracic duct receives lymph from only the left half of the body.
B.
The right lymphatic duct receives lymph from only the right half of the body.
C.
The thoracic duct receives the majority of the lymph from the body.
D.
The right lymphatic duct receives the majority of the lymph from the body.

C.  The thoracic duct receives the majority of the lymph from the body.

Explanation:

"Lymph" is considered the fluid that goes through the body's lymphatic system.

The "thoracic duct" receives majority of the lymph from the body–accounting to 75% of the total lymph. It doesn't only receive lymph from the left half of the body but from the entire body. So this makes choice A incorrect and choice D incorrect.

The right lymphatic duct doesn't only receive lymph from the right side of the body, it may also collect lymph from the lower lobe of the left lung. So this makes choice B incorrect.
