What is the difference between term and premature babies?

Full-term infants refer to babies born at 37 weeks of gestation and less than 42 weeks of gestation, while premature infants refer to babies born at 28 weeks of gestation and less than 37 weeks of gestation. The weight of full-term infants can reach more than 5000g. The weight of premature infants is generally within the range of 2500g-5000g. This is the main difference between the two.
