It contains a lubricating fluid and isolates the heart from body movements such as the expansion and contraction of the nearby pleural (lung) cavity. [14], Studies have shown that litter size, the amount of floor space during the growing period, and the number of pigs the gilt, or female pig, is placed with while growing affect the reproduction rates of the gilts. You have already seen how the esophagus leads from the pharynx through the neck region. Your finished cut will be anterior to the navel and along each side of the navel. The kidney is made up of three different regions internally: the outer cortex, the middle medulla (with the renal pyramids) and the inner-most renal pelvis. Accumulated urine will pass out of the bladder via the urethra, which in female pigs will fuse with the vagina. This diagram shows that the ductus arteriosus connects the pulmonary artery to the aorta and diverts blood that would otherwise go to the lungs. On the 84th day, Periarteriolar lymphoid sheaths appear in the fetal pig. Then, The oral cavity of the fetal pig begins developing before birth. Find the bile duct that leads to the small intestine.

An adequate amount of floor space allowed the higher percentage of gilts to reach puberty sooner than those gilts who had less floor space. Figure 36. By this time, the liver and bone marrow are active and functional. xref
Next, two or more types of tissues make an organ. In order for digestion to occur, the fetal pig would have to ingest food. Several peer-reviewed comparative studies have concluded that the educational outcomes of students who are taught basic and advanced biomedical concepts and skills using non-animal methods are equivalent or superior to those of their peers who use animal-based laboratories such as animal dissection. Figure 47. The cecum is a blind pouch where the small intestine joins the large intestine. When breathing, air passes through the nasal passages to the nasopharynx. This procedure generally happens reasonably slowly and gets worse with time, hence why it is so imperative to catch it timely. Biology @ Davidson.
