Solution

Humoral immunity Cell-mediated immunity
It is so called as it is generated by components circulating in the body fluids. It is so called as cells are directly involved in killing or destroying the infected cells.
It is generated by B cells that secrete antibodies in response to the infection. It is generated by T-cells. Some other cells such as dendritic cells may also be involved.
Interaction of B-cells with their receptors need to occur. Interaction of T-cells with their receptors need to occur.
Memory response in response to the pathogen may be seen. This results in the generation of heightened response on the second infection. No memory response is seen.
The two types of immunity that a baby is born with are the humoral immune system and the cell mediated immune system.
