Quizplus · Accepted Answer

The thymus gland is located anteriorly to the heart and is responsible for the development and maturation of T-cells, an important type of immune cell. The spleen is located on the left side of the body and filters blood, removing old or damaged red blood cells as well as pathogens. The right lymphatic duct is a lymphatic vessel that drains lymphatic fluid from the right arm, right side of the chest and head into the bloodstream. Axillary lymph nodes are located in the armpit and filter lymphatic fluid from the arms and chest. None of these organs are primarily responsible for the development of the immune system, making choice A the correct answer.
