Delaware Barbering Practice Exam

Lymph is the fluid that exchanges its nutritive materials with the cells. It is clear that blood is incorrect because it only carries oxygen and nutrients to the cells, but does not directly exchange them. Water and saliva may contain some nutrients, but they do not actively exchange them with the cells. Lymph, on the other hand, carries important nutrients and immune cells to the cells, while also picking up waste products to be eliminated by the body. Therefore, lymph is the most correct and specific answer to this question.
