The lungs go through 4 distinct histological phases of development and in late fetal development thyroid hormone, respiratory motions and amniotic fliud are thought to have a role in lung maturation. Branching is a key mechanism/process in lung development leading to alveolar saccules after about 23 branching generations (range of 18–30).
21 de jul. de 2023 · Phases of development Embryonic The embryonic phase takes place between the third and sixth week of gestation. The development of the lungs begins during the third week, with the appearance of a respiratory diverticulum (lung bud) as an outgrowth from the ventral wall of the foregut.
1 de feb. de 2014 · Overview of the stages of lung development. Lung endoderm specification begins at ∼E9.0 on the ventral side of the anterior foregut endoderm (yellow) where initiation of Nkx2.1 expression commences. By E9.5-E10.0, the formation of the trachea is observed and the embryonic stage of lung development begins and ends at E12.5.
Embryonic phase. Pseudoglandular phase. Canalicular phase. Saccular phase. Alveolar phase. Classification in the adult lung. Introduction. In comparison with the development of the other organs the prenatal development of the lungs occupies a special position. The lungs as breathing organs are unnecessary for intrauterine existence.
2 de oct. de 2020 · The lung development is subdivided into three main overlapping periods: the embryonic, the fetal and the postnatal period. Interestingly their functional maturation is not achieved at birth.
