However, increasing FPR does not prove to increase litter size. The arteries have been filled with red latex and the veins with blue. The study suggests stress plays a role in impacting the reproduction. In this particular dissection a fetal pig was used because the organs present in a pig, and their position in the body are similar to those of humans which provides insight on how human organs systems work overall and why they are essential to life. 21. Note that you will need to remove some of the pyramids to see the remaining structures, which lie underneath. Extend a single cut along the midline of the ventral surface of the animal to about 2 cm. Anatomy of the Urinary System. Both rejection control and urinary excretion system establishment are required to develop fetal kidneys into more mature kidneys in recipients [14]. Continue separating the tissue with a probe until the trachea and esophagus are exposed. Remove one kidney from the fetal pig by severing the ureter.
