Embrióa

Embrióa is a term used in some contexts to refer to the early stage of development of a multicellular organism. This stage typically begins after fertilization, when a zygote starts to divide and differentiate. The period of embryonic development is characterized by rapid cell division, growth, and the formation of specialized tissues and organs. The specific characteristics and duration of the embryonic stage vary significantly between different species. In humans and other mammals, this stage is often referred to as the embryonic period, which lasts for the first eight weeks of gestation. During this time, the fundamental body plan is established, and major organ systems begin to form. Following the embryonic stage, the developing organism is usually termed a fetus, and further growth and maturation of existing organs occur. The study of embryonic development is a crucial aspect of biology and developmental biology, providing insights into fundamental life processes and the origins of congenital abnormalities.
