Final answer:
Lymphocytes, including B-cells and T-cells, are the cell types that carry lymph, being integral components of the adaptive immune system.
Step-by-step explanation:
The cell type that carries lymph is the lymphocyte. Lymphocytes are white blood cells characterized by a large nucleus and small rim of cytoplasm. They circulate in the bloodstream and lymph, and are primarily found in secondary lymphoid organs, such as the spleen and lymph nodes. The two main types of lymphocytes are B-lymphocytes (B-cells) and T-lymphocytes (T-cells). These cells play a significant role in the adaptive immune response.
