Question

A fully developed foetus initiates its delivery from the mother’s womb. Justify

the statement.​

Answer 1

Answer:

In humans, the fetal stage starts nine weeks after fertilization.[9] At the start of the fetal stage, the fetus is typically about 30 millimetres (1.2 in) in length from crown-rump, and weighs about 8 grams.[9] The head makes up nearly half of the size of the fetus.[10] Breathing-like movements of the fetus are necessary for the stimulation of lung development, rather than for obtaining oxygen.[11] The heart, hands, feet, brain and other organs are present, but are only at the beginning of development and have minimal operation.[12][13] The genitalia of the fetus starts to form and placenta becomes fully functional during week 9.[14]

At this point in development, uncontrolled movements and twitches occur as muscles, the brain, and pathways begin to develop.[15]

Answer 2

Answer:

The process of giving birth to a fully developed foetus is called PARTURITION, which is initiated by a hormone named OXYTOCIN

Explanation:

The process of birth of the fetus is called PARTURITION. PARTURITION is the act of expelling the full-term fetus from the mother's womb at the end of pregnancy. In this process, the fully developed fetus produces a fetal ejection reflex that stimulates the pituitary to release the hormone OXYTOCIN. This hormone causes strong uterine contraction that leads to the birth of the fetus. This process is also known as the delivery of the fetus when the pregnancy period is over. The significance of birth is that the event results in the fetus emerging from the womb. The process is accompanied by the onset of Lactation.
