Which term refers to the fluid that aids in the transport of waste products from cells?

The term that specifically refers to the fluid that aids in the transport of waste products from cells is blood. Blood serves as the primary transport medium in the circulatory system, carrying not only oxygen and nutrients but also metabolic waste products such as carbon dioxide and urea away from tissues. These waste products are then delivered to organs such as the kidneys and lungs for excretion from the body.

In contrast, the other choices have different roles or characteristics. Intercellular fluid refers to the fluid found between cells, which helps in the exchange of substances between them but does not serve as a primary transport medium for waste as blood does. Lymph is a fluid that circulates in the lymphatic system and is primarily involved in immune functions as well as the transport of certain waste products, but its specific purpose differs from that of blood. Serum, a component of blood, is the liquid that remains after coagulation and does not include cells; while it can contain waste products, it is not the main transport fluid involved in waste removal from the body.
