The respiratory system helps you breathe. The main parts of the respiratory system are the lungs, the airways, and the muscles that enable breathing. The circulatory system, which is made up of the heart, veins, arteries, and capillaries, brings blood to and from the lungs and delivers nutrients and oxygen to tissues of the body while removing carbon dioxide and waste products. Other body systems that work with the respiratory system include the nervous system, lymph system, and immune system.

RDS is a type of neonatal respiratory disease that is caused most often by a lack of surfactant in the lungs. A fetus's lungs start making surfactant during the third trimester of pregnancy, or weeks 26 through labor and delivery. Surfactant coats the insides of the air sacs, or alveoli, in the lungs. This helps keep the lungs open so breathing can occur after birth.
