Lungs

An introduction to the lungs...

On this page, we will be exploring the development of the lungs through the stages of embryonic growth.


Developmental origin overview

Developmental timeline

Year
Historical Development
1600s
Marcello Malpighi (1628-1694) pioneered the use of the first microscope which paved the way for many discoveries in his fields of embryology and botany. One of his many significant discoveries included identifying pulmonary capillaries in frogs; published in 1661 in De pulonibis [1]
1810-1820s
Christian Pander, Karl Ernst von Baer, and Heinrich Rathke were among the first to use a new wave of technology in embryology; involving the use of new staining techniques and improved microscopy. Their findings together identified the presence of primary germ layers (ectoderm, endoderm and mesoderm) and the development of early organs. [2]
1817
Christian Pander furthered his research by studying chick embryos. Through this, he determined that the germ layers all worked together to form organs that gave significant evidence towards the notion of epigenesis. [3]
