14 weeks
The embryo of a human develops in the uterus of the female body. The uterus provides a protective and nourishing environment for the embryo to grow and develop into a fetus.
After the first eight weeks, the embryo is referred to as a fetus. At this stage, the major organs have formed and the fetus continues to grow and develop until birth.
During this time period, the embryo is known as a fetus. It continues to grow and develop, with its organs maturing and becoming more functional. By the time of birth, the fetus is fully developed and ready to survive outside the womb.
After a sperm fertilizes an egg its referred to as a zygote. Then it becomes a fetus, I believe after the first trimester.
The embryo grows and develops in the uterus of the female reproductive system. Once fertilization occurs, the embryo attaches itself to the uterine wall where it receives nourishment and continues to grow and develop into a fetus.
After fertilization, the embryo undergoes a series of cell divisions and differentiation to develop into a fetus. During this process, the embryo forms different organ systems and structures, such as the brain, heart, and limbs. By the end of the eighth week of development, the embryo is considered a fetus.
The job of an embryo is to develop and grow into a fetus. During this stage, the embryo undergoes cell division and differentiation to form the various tissues and organs of the body. The embryo is also dependent on the mother's body for nutrients and oxygen to support its growth.
Fetus
The first organ to develop in the embryo is the heart. In a fetus, there is a brain, but it isn't fully developed and can't understand signals from the nervous system. Therefore the first functional organ would be the heart. But the first thing to start developing in a fetus is the nervous system. ( no that isn't an organ )
It depends on what organism the embryo comes from.
lungs
No, an artificially implanted embryo cannot grow inside a male as the male body does not have the necessary biological structures, such as a uterus, needed for embryo implantation and growth. Embryos require a female reproductive system to develop and grow into a fetus.
