What is the Role of the Immune System in the Body?
The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens, such as bacteria, viruses, fungi, and parasites. It also plays a crucial role in identifying and eliminating abnormal cells, such as those that may develop into cancer. In histology, studying the immune system involves examining the structure and function of various immune cells and tissues under the microscope.
