The newborn lungs are located primarily in the chest, one on each side. The lungs of newborns are mainly located in the highest position of the human lungs, i.e. the chest, one on each side. Lungs have a very important role in human respiration, but since newborns are just born, if they are not well cared for they are likely to cause pneumonia, so usually try not to let newborns catch a cold, fever and so on. If the above symptoms are more serious, lung infection may occur. Usually the fetus will slowly develop and mature its lungs around 37 weeks and will breathe on its own after birth. If preterm labor occurs, severe cases may require ventilator-assisted therapy.
