In the last trimester, the fetus undergoes significant growth and development, gaining weight and accumulating body fat to prepare for life outside the womb. It also develops essential organs, including the lungs and brain, and begins to practice breathing movements. The fetus becomes more active, with increased movements and responses to external stimuli, such as sounds and light. Additionally, the brain undergoes rapid maturation, laying the groundwork for postnatal functioning.
