Trimester 1 Month 1: Gastrulation happens where blastocytes is implanted into the uterine lining to receive nutrients and cells divide into three cell layers called the gastrula. The gastrula includes the ectoderm, mesoderm, and endoderm. The ectoderm develops the skin and nervous system, the mesoderm develops the muscles, bone, heart, kidneys, blood vessels and reproductive system, and the endoderm develops the liver, lungs, certain glands, and digestive system. Month 2: Progress of neurulation starts which develops the nervous system. The ectoderm thickens and folds to develop the brain and spinal cord. The amniotic sac and placenta forms so protection and nutrients are given to the embryo. Month 3: Embryo is now a fetus, and the organs are fully formed but not fully functioning. Trimester 3 The fetus grows, doubling its mass. Its lungs and other organs prepare for life outside the uterus. The eyelids finally open and the body is able to store nutrients and minerals. By month 9, the fetus is ready to live outside the womb. Trimester 2 A heartbeat can be heard, and cartilage is replaced by bone. The fetus' intestines use the umbilical cord to return to the abdomen and urine begins to form and discharge. The fetus develops its liver and pancreas function, brain function, and control of body functions. The fetus' ovarian follicles or prostate gland begin forming depending on gender and fingerprints, eyebrows and eyelashes grow in.
