FETUS Meaning and
Definition
-
A fetus is a stage in the development of a mammal, including humans, starting from the end of the embryonic period until birth. It represents the advanced or mature phase of gestation where the unborn offspring has formed recognizable features and organs. During this stage, the fetus primarily grows in size and experiences substantial structural changes as it transitions into a fully formed individual.
Typically, the development of a fetus involves a complex and intricate process that encompasses various stages. After conception and the initial formation of an embryo, the fertilized egg undergoes significant cell division, differentiation, and organogenesis to transform into a fetus. As it develops, the fetus develops characteristics such as limbs, a head, facial features, and internal organs. The circulatory, respiratory, digestive, and nervous systems progressively develop and become functional during this phase.
The fetus is nurtured and protected within the uterus of its mother through the placenta, which enables the exchange of nutrients, oxygen, and waste materials between the mother and the fetus. It is only after reaching a specific level of development and maturation that the fetus is deemed capable of surviving outside the mother's womb, at which point it is considered ready for birth.
Understanding the fetal stage is crucial in the field of obstetrics and prenatal medicine. Healthcare professionals monitor fetal development through various imaging techniques and tests to ensure the wellbeing of both the fetus and the mother during pregnancy. Studying the fetus also aids in identifying any potential abnormalities or complications that may require medical intervention.

Etymology of FETUS
The word "fetus" comes from the Latin word "fetus", which means "offspring" or "bearing young". This term originated in the late 14th century and was mainly used to refer to the young of animals or humans before they were born. The Latin word, in turn, is believed to have evolved from the Indo-European root "*dhe(i)-", meaning "suck, suckle" or "nourish". The usage of the term "fetus" to specifically refer to the developing unborn child in the womb began in the late 18th century.
