fetus
the developing human organism from 9 weeks after conception to birth ○ During sixth month, organs such as stomach have developed enough to give the fetus a good chance of survival if born prematurely ○ Fetus is responsive to sound and exposed to the sound of its mother -20-24 weeks: sense of taste and smell
A fetus is the stage of prenatal development between the 9th week after fertilization and birth. At this stage, the developing embryo has undergone significant morphological changes and has all organ systems in place. The fetus is typically about 3 inches long and weighs approximately 1 ounce at the end of the first trimester.
During the second trimester, the fetus experiences rapid growth in size and weight, and its organ systems become more mature, including the lungs, digestive system, and nervous system. In the third trimester, the fetus continues to grow and develop, and the brain undergoes important changes as it prepares for life outside the womb. It is during this stage that the fetus also gains the ability to regulate its body temperature.
Overall, the fetus is a crucial stage in the development of a human being, and it is during this time that many important developmental milestones occur.
