These are organs where maturation and proliferation of lymphocytes takes place. Lymphoid organs where T and B lymphocytes mature and acquire their antigen - specific receptors are called Primary Lymphoid organs. Bone marrow (site of B cell maturation) and Th..

Chemical evolution resulted in the formation of life on earth about 3.8 billion years ago. The primitive cells that resulted from this process gradually gave rise to primitive forms of organisms such as bacteria, algae, fungi and protozoan. These organisms in tur..
