10.3: Cardiovascular and Respiratory Systems Lab After this lab, you will be able to state the parts of the cardiovascular and respiratory systems and give the functions of each part, identify the parts of the cardiovascular and respiratory systems on the human torso model and other models, and explain how the respiratory and cardiovascular systems are interrelated.An incision was made on the side of the neck to enable the injections. The arteries have been filled with red latex and the veins with blue. Trace the abominal aorta (also called the dorsal aorta) to the lower part of the body, careful tweezing of the tissue will reveal several places where it branches, though some of the arteries may have been cut when you removed organs of the digestive system. The fetal pig that you will dissect has been injected with a colored latex (rubber) compound. Fetal Pig - Dissection of the Lower Arteries. Digestive System: The digestive system of the fetal pig includes the mouth, esophagus, stomach, small intestine, and large intestine. Lift the trachea and esophagus and cut the bottom connective tissue. The esophagus is one of the first sections of the digestive system and leads to the stomach. Usually a 10 in × 12 in (25 cm × 30 cm) or larger tray will do the trick. Limbs: Four limbs with hooves are present, and the skeletal structure is visible. Eyes and Ears: Fetal pigs have well-developed eyes and ears. Use a tray large enough to fit the fetal pig. Heres an overview of key anatomical features in a fetal pig: Size and Weight: Fetal pigs used in dissection are typically around 12-16 inches in length and weigh a few pounds. 10.2: Reading: Fetal Pig Dissection In this reading, you will find detailed instructions on fetal pig dissection as well as many images which locate and identify different organs found in fetal pigs. Put the fetal pig onto a separate dissection tray.During this lab, you will learn about the anatomy of the pig as an example of a vertebrate mammal, identify structures on the pig and know their functions, and identify structures that are a part of the digestive system, respiratory system, circulatory system, reproductive system, and excretory system. The diagram will help students identify and understand the role of. Digestive System: The digestive system of the fetal pig includes the mouth, esophagus, stomach, small intestine, and large intestine. 10.1: Fetal Pig Dissection Lab In this lab, you will perform a dissection of a fetal pig. A labeled diagram of the fetal pig dissection helps students identify and locate the different organs and systems within the pig’s body.
