The Word Becomes Flesh

Lyrics for The Word Becomes Flesh

The head of the embryo grows forward and the gut elongates rearward The neural folds meet in the brain region, but fuse At this stage, four pairs of somites, blocks of mesodermal tissue, have formed As the head of the embryo grows forward The head fold further undercuts its anterior end The neural folds fuse to form new sets Anterior end develops into a three-part brain Early structures of the eye are now prominent Meanwhile The embryo develops in an equally exciting manner In its later stage, a small embryo is already visible As a light-colored disk Soon, blood vessels appear outside the embryo The heart develops and begins to beat The pattern of blood vessels over the egg expands Supplying the embryo with food and oxygen and removing waste As the embryo grows, the brain, eyes, and other structures develop Soon, a vigorously beating heart is pumping blood throughout the complex embryo, which is rapidly developing into a mature organism The blastoderm, the area pellucida is translucent because it is over a liquid And the white of the egg Vessels over the yolk expand Some of the albumen becomes thickened and twisted as the egg passes down the oviduct These rope-like strands, called the chalazae, help to hold the cell in position The blastoderm at this stage consists of many cells produced by repeated cell division While the egg is still within the organism
