* Embryo: This refers to the developing human organism from the moment of fertilization (when the sperm and egg meet) until the end of the 8th week of pregnancy. During this period, the embryo undergoes rapid growth and development, forming major organs and systems.
* Fetus: From the 9th week of pregnancy until birth, the developing human organism is referred to as a fetus. During this stage, the fetus continues to grow and mature, preparing for life outside the womb.
Therefore, "embryo human" is redundant because "embryo" already refers to the developing human organism.
Important Note: There are ethical and philosophical considerations surrounding the use of terms like "embryo" and "fetus," and different individuals may have different views on when human life begins. These are complex discussions that are beyond the scope of a simple definition.
