Medical visualization taken from human scanned data showing a fetus at 24 weeks. At this stage of development, the circulatory system of the fetus is expanding, especially in the lungs. The blood vessels can be seen through the skin, as it is still transparent. The lungs have begun to produce surfactant, a substance that keeps the air sacs in the lungs from collapsing and sticking together when exhaling and allows for easier inflation when we inhale. Lack of sufficient surfactant (along with incomplete structural development) is responsible for infant respiratory distress syndrome in premature babies. | |
