Gastrulation is defined as a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a trilaminar structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and endoderm. These develop into the respiratory and digestive organs.
The brain is the last to develop fully, which is around 24 in males.
Young are developed in the uterus (womb).
one cell can become one baby becuase it is in a seperate egg and it starts to grow and develop its organs
When organs are viewed according to their shared functions they form organ systems. Organ Systems are formed from Organs, and from Tissues, which ultimately are formed from living units called cells. These organ systems usually develop as an adaptation or natural selection calls for some sort of function, and continues to develop with the evolutionary timeline.
