Immunology & Cell Biology
Immunology (pronounced: /ˌɪm.jʊˈnɒl.ə.dʒi/) is a branch of biology that covers the study of immune systems in all organisms. The term is derived from the Latin immunis, meaning "exempt" or "free", and the Greek -λογία (-logia), meaning "study of".
Immunology has applications in numerous disciplines of medicine and science, and is the key to understanding the causes of most diseases. It involves studying the complex network of cells, tissues, and organs that work together to defend the body against harmful invaders.
Related terms include antigen, antibody, immune response, immune system, immunity, inflammation, leukocyte, lymphocyte, macrophage, pathogen, and phagocytosis.
Cell Biology (pronounced: /sɛl baɪˈɒlədʒi/) is a scientific discipline that studies cells – the fundamental units of structure and function in living organisms. The term is derived from the Latin cella, meaning "small room", and the Greek -λογία (-logia), meaning "study of".
Cell Biology encompasses both prokaryotic and eukaryotic cells and can focus on cell morphology and function, cell life cycle, the organization of cells in tissues, and the role of cells in disease.
Related terms include cell membrane, cytoplasm, endoplasmic reticulum, golgi apparatus, mitochondria, nucleus, organelle, ribosome, and vesicle.
