Script: razvija do svojega rojstva.

Pri dveh tednih in pol se iz epiblasta oblikujejo tri specializirana tkiva oziroma klične celice imenovane ektoderm, entoderm in mezoderm.

Iz ektoderma se razvijejo številna tkiva, kot so možgani, hrbtenica, živčevje, koža, nohti in lasje.

Iz entoderma pa se razvijejo dihalni in prebavni sistem ter tudi veliki organi, kot so jetra in trebušna slinavka.

Iz mezoderma se razvijejo srce, ledvice, kosti, hrustanec, mišice, krvne celice in druga tkiva.

All ages referenced to fertilization, not last menstrual period.
