The 'breech' refers to the rear part of a firearm barrel, where the cartridge is loaded. Think of it as the gun's loading dock. It's crucial for sealing the explosion that propels the bullet. In biology, 'breech' can describe an abnormal birth position where the baby emerges feet or buttocks first. It's like entering a building through the back door instead of the front. For guns, the breech needs to be strong; for babies, the position requires extra care.
