They also allow for the study of fetal circulation, which differs from that of an adult. It extends along the length of the stomach from the left side of the body (your right) to the point where the stomach joins the small intestine. The kidneys' are a vital part in the process of removing urine from the body. The efficiency at which nutrients are transferred dictates the health and growth of the fetus. An incision was made on the side of the neck to enable the injections. The cecum is a blind pouch where the small intestine joins the large intestine. A similar cut is made on the other side. You will need to cut through the musculature and the joint that holds the lower jaw to the skull. Continue separating the tissue with a probe until the trachea and esophagus are exposed. 2014-06-13 22:17:22. Real pigs are not as .

Contraction of the diaphragm forces air into the lungs. The pulmonary artery is capable of delivering a large amount of blood to the lungs but the lungs are not needed to oxygenate the blood of a fetus, so most of the blood is diverted to the aorta. Use your pig and also a pig of the opposite sex to identify the structures in the photographs below. 70 0 obj <> endobj Each lung is located in a body cavity called a pleural cavity. The path that urine takes to exit the body is very specific. Use a scalpel to cut the sides of the mouth so that the bottom jaw can be opened for easier viewing (see figure 11). Although increasing placental fold width does increase the interaction between fetus and mother, nutrient exchange is not most efficient in smaller fetal pigs, as would be expected. 0000005624 00000 n Tie one front leg of the animal with a string that passes underneath the dissecting pan to the other leg. <<0A8475290F23494581369D9CD21F7021>]>> The male's internal reproductive system has two scrotal sacs, which depending on the age of the fetal pig may or may not have developed testes. The first branch of the aorta is the brachiocephalic artery. Abstract The high-prevalence blood group antigen, Sda, had been puzzling blood bankers and transfusionists for at least a decade when it was reported in 1967. Fetal Pig Programming - An Emerging Concept with Possible Implications for Swine Reproductive Performance. By this time, the liver and bone marrow are active and functional. The next system I dissected was the respiratory system. I found the trachea to be wider, stronger, and it had a bumpy surface. Fetal Pig Practice Quiz - ll in blanks and self check. Fourthly, fetal pigs are easy to dissect because of their soft tissue and incompletely developed bones that are still made of cartilage. Between the two folds of peritoneum onto the surface of the liver to the diaphragm is comprised bare surface of the liver, an area in which the peritoneum covering the liver capsule. The fetal pig urinary tract is relatively developed and easy to locate during dissection. However, clear urine production and discharge could not be confirmed, suggesting the possibility of urinary retention. Aorta, colon (large intestine), diaphragm, heart, kidney, lung, renal artery, posterior vena cava, renal vein, small intestine, spleen, stomach, ureter. . Fetal Pig - Urinary System . Urinalysis. Continue cutting from the anterior end of this cut so that it resembles an upside-down U. The calyces are the tube-like extensions from the renal pelvis. Pin the anterior and posterior end of the organism (earthworm, frogs, or fetal pig) to the dissecting tray. You should not remove these structures yet because you will need to identify the blood vessels later in the dissection. Using a probe, trace follow the esophagus to thestomach. The amount of floor space has been shown to impact the time it takes gilts to reach puberty. In the photograph below, the heart and blood vessels of the neck region have been removed so that the trachea can be seen more clearly. Figure 12. Using a scalpel, follow the directions in this step, making . Repeat this with the back leg. Reproductive System Anatomy. Instead, a more accurate way of determining fetus growth is through certain characteristics of the placental lining. 193, 105119.

The large hard structure attached to the trachea is the larynx. The following words will be used to help identify the location of structures. Likes. The pharynx is the space in the posterior portion of the mouth that both food and air pass through. Cut completely through the body wall in the abdominal area but keep the cut shallow in the neck region. Esophagus, larynx, trachea, bronchus, and lungs. Figure 26. It contains a lubricating fluid and isolates the heart from body movements such as the expansion and contraction of the nearby pleural (lung) cavity. The Urinary System. a) The by-product that causes the pigment of urine is urochrome. While pictures are useful for learning the anatomy of the fetal pig, be careful with only memorizing drawings. This lab centers on the dissection of the urinary system of the fetal pig. The foramen ovale normally closes up at birth, keeping blood flow of the two sides of the heart completely separate. The pulmonary artery is capable of delivering a large amount of blood to the lungs but the lungs are not needed to oxygenate the blood of a fetus, so most of the blood is diverted to the aorta. [13], The development of the lymphatic system and the formation of blood circulation occur at different stages of fetal pig development. These two cuts will enable you to spread open the abdominal cavity. The astounding part of the living organisms have led us some understanding of the awe-inspiring structure of every life from as small as 0.0000001 to over 0.1. Suburban Science. The pulmonary artery is capable of delivering a large amount of blood to the lungs but the lungs are not needed to oxygenate the blood of a fetus, so most of the blood is diverted to the aorta. the integumentary system and body membranes, plus coverage of the skeletal, muscular, nervous, endocrine, circulatory, respiratory, digestive, urinary and reproductive systems, development, heredity, surface anatomy, dissection exercises, PhysioEx Computer Simulations, PhysioEx Review .
