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.Learn More
The small intestine of a fetal pig can be as long as 12 feet long when it is separated from the mesentery. Within the small intestine, food is digested and absorbed.Full Answer >
According to Goshen College's Fetal Pig Dissection Guide, a fetal pig's anatomy is similar to the anatomy of a human because both animals are mammals, and both contain the same vital organs. Pigs have the same muscles as humans in almost every case; however, since pigs are quadrupedal and humans are bipedal, there are small variations between size and location of some muscles.Full Answer >
A fetal pig's approximate age is determined by measuring its body length from the base of its tail to the tip of its snout, according to Massengale's Biology Junction. Unless the fetal pig is underdeveloped, this is a fairly accurate and easy way to determine how many weeks it developed prior to its death.Full Answer >
In quadruped animals such as pigs, the sartorius muscle acts to adduct the hind leg, meaning it pulls the leg inward toward the center of the body. The sartorius muscle is located in the thigh and runs from the hip joint along the inside of the thigh to the knee.Full Answer >
