What is the developing human organism from 9 weeks after conception to birth?

• A. Endometrium
• B. Oocyte
• C. Placenta
• D. Fetus

Answer: (D)

From nine weeks after conception to birth, the developing human is called a fetus. This stage starts after the embryo-forming period, when most major organs have already formed and the body now grows and the organs mature to function outside the womb. So, the term fetus specifically refers to the developing organism during this later phase, not to the placenta, the uterine lining, or an egg cell. The placenta stays as the lifeline that nourishes and supports the fetus, while the endometrium is the uterine lining, and an oocyte is an egg cell.
