Hint:
The immune system is a complex network of cells, organs, and proteins that defends the body against infection, without affecting the body's cells. There are two types of immune systems in the body, the innate immune system, and the adaptive immune system. Innate immunity is the defence system with which we are born and protect against all antigens. Adaptive immunity is the immunity acquired by the body in response to vaccination or exposure to pathogens.
Complete step by step answer:
Many cells play a major role in innate immunity like phagocytes (neutrophils and macrophages), mast cells, dendritic cells, basophils, natural killer cells, innate lymphoid cells, and eosinophils. Phagocytes are further categorized into two main cell types: macrophages and neutrophils.
Both cells function by engulfing microbes and killing them through multiple microbicidal pathways. In addition to this property, neutrophils contain granules and enzyme pathways that help in the elimination of pathogens. Macrophages are large amoeboid cells present in areolar tissue. Unlike neutrophils which are short-living, macrophages are long-living and they carry out phagocytosis and antigen presentation.
Adipocytes are the fat cells that help in the composition of adipose tissues. Fibroblasts are the cells that help in the formation of connective tissues. Even though mast cells are part of the immune system, they are not amoeboid cells.
Option ‘C’ is correct
Note:
Innate immunity controls infections during the first seven days after infection. Many of the cells in the innate immune system as macrophages, dendritic cells, mast cells, neutrophils, eosinophils, and basophils produce cytokines or interact directly with other cells to activate the adaptive immune system.
