Q:

How many lung lobes does a fetal pig have?

A:

According to the State University of New York, a fetal pig has a total of seven lung lobes. The right lung is larger and is divided into four lobes: the apical, cardiac, diaphragmatic and intermediate. The left lung has three lobes because it does not have an intermediate lobe.

Each lung is located in a separate pleural cavity, which is the space between the lung and the thoracic body wall. A fetal pig's lungs have pleural membranes. One pleural membrane lines the inner surface of the pleural cavity, and the other covers the outer surface of the lung. The lungs of a fetal pig are almost solid because they have never been inflated. Once inflation occurs, the lungs have a spongy appearance.
