so pigs can breathe.
When the lungs do not function the backup respiratory system takes over the function of the lungs. This is true in a fetal pig.
The main function of a pig's trachea is to breathe. It is part of system of passages that allow air into the lungs.
Yes, the diaphragm does function in fetal pigs. It helps facilitate breathing by separating the thoracic and abdominal cavities, allowing the piglet to inflate its lungs as it transitions to breathing air after birth.
Fetal lungs are not functioning; no organism can start to breathe while immersed in amniotic fluid. Lungs only begin to function at birth.
Pig lungs.
Lungs collect oxygen.
The placenta. Deoxygenated blood flows to the placenta where the carbon dioxide is removed and oxygen added. Oxygen rich blood returns to the fetus. Blood is carried to and from the fetus by the umbilical cord.
Yes, the diaphragm is an essential muscle involved in breathing in both mature pigs and pig fetuses. In a developing fetus, the diaphragm starts to form during early stages of development and continues to grow and strengthen throughout gestation to prepare for breathing after birth.

A fetal pig's lungs are collapsed because they are filled with fluid while in the uterus. This allows for easier passage through the birth canal and prevents the lungs from being damaged during development. Once the pig is born and takes its first breath, the lungs expand and fill with air.
