The pulmonary development is extremely complex and highly ordered, a process involving several cell types, which are involved in different phases of development, beginning in the embryonic phase until the differentiation and specialization of cells forming specialized organs. The development of respiratory system (larynx, trachea, bronchi and lungs) begins in the fourth week of embryonic development, and remains incomplete until the last weeks of fetal development, becoming mature just before the birth.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
