What is a fetus

A fetus is a stage in the development of a mammal, particularly in the human species, from the embryonic stage to birth. It is a developing offspring in the uterus of a pregnant female, from the ninth week of gestation until birth.

During this stage, the major organs and body systems continue to develop and mature. The fetus receives oxygen and nutrients from the mother's bloodstream via the placenta and umbilical cord. The fetus's growth and development are influenced by the mother's health, lifestyle, and nutrition, making prenatal care crucial.

In biological terms, the fetus is characterized by the formation of major organs, the development of senses, and the improvement of motor skills. Although the fetus is still dependent on the mother, it is a separate individual with its own unique set of DNA.

While I didn't find any specific products or services related to the definition of a fetus, if you're looking for resources on fetal development or pregnancy, I recommend consulting reputable sources such as the American Pregnancy Association or the Centers for Disease Control and Prevention (CDC).
