First Trimester
The first trimester of pregnancy is a crucial time for the development of your baby’s organs. By week four, the neural tube has formed, which will later become the brain and spinal cord. By week five, the heart begins to beat and pump blood. The liver, kidneys, and intestines also start to form around this time.By the end of the first trimester, your baby’s major organs have formed, although they are not yet fully functional. This is also the time when the placenta fully develops, taking over the job of providing your baby with oxygen and nutrients.
Second Trimester
During the second trimester, your baby’s organs continue to mature and become more functional. The lungs start to produce surfactant, a substance that helps them expand and contract properly. The digestive system becomes more efficient, and the liver begins to process waste products.By the end of the second trimester, your baby’s senses are also developing. They can hear your voice and may even react to noises outside the womb. Their eyes can detect light, although their vision is not yet fully developed.
Third Trimester
The third trimester is a time of rapid growth and development for your baby. They gain weight and start to fill out, preparing for life outside the womb. During this time, their brain also undergoes significant growth and development.By week 32, most of your baby’s major organs are fully functional, although their lungs may not be fully mature until closer to 39 weeks. The digestive system is also fully functional, and your baby is practicing swallowing and passing stool.
