How Do Baby Birds Breathe Inside Their Eggs?
The two membranes pull apart a little
and create a small pocket or sack of air. As the developing bird grows, it
breathes in oxygen from the air sack and exhales carbon dioxide. Several
thousand microscopic pores all over the surface of the egg allow the CO2 to
escape and fresh air to get in.
The chalazae stabilize the yolk and embryo in the canter of the egg within the albumen layers. The chalazae become twisted as the egg is turned during incubation. The hard outer surface of a bird egg is the shell. Just like humans, animal babies that grow inside their mothers receive everything they need to develop within the safe confines of the womb through an umbilical cord that collects some of the oxygen that the mother breathes, along with other forms of nourishment.
However, when it comes to animals (like chickens) that grow inside an egg, the process obviously can’t be as straight forward, right? Since an egg is completely devoid of any visible holes or openings, it is entirely shut out from the outside world, so how does the little one nestle inside to get the all-important the oxygen it needs to perform vital biochemical functions?
