Baby submerged, instinctively holding his breath underwater. Infant swimming is the phenomenon of human babies and toddlers reflexively moving themselves through water and changing their rate of respiration and heart rate in response to being submerged. The slowing of heart rate and breathing is called the bradycardic response. [1]
Birth. Lambing: the mother licks the first lamb while giving birth to the second. Birth is the act or process of bearing or bringing forth offspring, [ 1] also referred to in technical contexts as parturition. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a ...
Human growthand development. A fetus or foetus ( / ˈfiːtəs /; pl.: fetuses, foetuses, rarely feti or foeti) is the unborn offspring that develops from a mammal embryo. [1] Following embryonic development, the fetal stage of development takes place.
Learning language as an infant also requires fetal memory. It is now known that the mother's voice is clearly heard from inside the womb and that the fetus can differentiate speech sounds, particularly the phonemes (a single segment of sound) in speech. This is evident in the baby when born, showing many signs of early language comprehension.

Wade, the 1973 landmark case that legalized abortion in the United States and was essentially overturned in 2022. [2] [3] The concept of fetal rights has ...
Fetal movement refers to motion of a fetus caused by its own muscle activity. Locomotor activity begins during the late embryological stage and changes in nature throughout development. Muscles begin to move as soon as they are innervated. These first movements are not reflexive, but arise from self-generated nerve impulses originating in the ...
Human embryonic development or human embryogenesis is the development and formation of the human embryo. It is characterised by the processes of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled ...
