Verified step by step guidance

Begin by identifying the primary function of each organ system listed in the problem. The respiratory system is primarily responsible for gas exchange, the endocrine system for hormone regulation, and the digestive system for nutrient absorption and waste elimination.

Consider the role of the lymphatic system, which is not listed among the options but is mentioned as the correct answer. The lymphatic system is crucial for immune function and maintaining fluid balance in the body.

Understand that the lymphatic system includes lymph nodes, lymph vessels, and lymph fluid. It plays a key role in filtering and removing foreign substances, such as pathogens and debris, from the blood.

Recognize that the lymphatic system works closely with the circulatory system to transport lymph fluid, which contains white blood cells that help fight infections and remove foreign substances.

Conclude that the lymphatic system is indeed responsible for removing foreign substances from the blood, as it filters lymph fluid through lymph nodes where immune responses can be initiated.
