A text in Czech: Zygota se přetváří na shluk buněk zvaný morula, který se pod mikroskopem podobá plodu moruše. Morula se pomalu přesunuje vejcovodem do dělohy, kam dorazí asi za tři dny.
What's the text in English? It transforms the zygote into a cluster of cells called a morula which, seen through a microscope, resembles a mulberry. The morula slowly moves down the Fallopian tubes toward the uterus, where it arrives after about three days.
