Name the two types of immune systems in a human body. Why are cell mediated and humoral immunities so called?

Two types of immune systems in a human body are acquired and innate.
Cell mediated immunity is called so because cells like T-lymphocytes provide immunity/T-cells kill or destroy the antigens.
Hum oral immunity is called so because it consists of antibodies that are present in humans or body fluids, whereas cell-mediated immunity is provided by B-cells and T-cells.
