preserved pig 2 dissecting trays hand lens forceps probe organ chart damp towel plastic wrap Part 1: External Anatomy 1. Place your pig in a dissecting tray. Using a ruler, measure the length of the pig from the snout to the tail. Use the graph in Figure 1 to estimate the age of your fetal pig: _____ SAFETY CONCERNS

Saliva: The saliva is found all throughout the pigs digestive system but mainly in the mouth.… pancreas/duodenum homeobox protein 1, homeodomain protein PDX-1. GeneRIFs: Gene References Into Functions. It is a gene that is crucial for pancreas development during the fetal period and whose monoallelic disruption impairs insulin secretion. Report pancreatic expression of Pdx-1 in pancreas. Fetal Pig Dissection Unit Objectives: Identify important external structures of the fetal pig. Identify major structures associated with a fetal pig's integumentary, skeletal, digestive, respiratory, circulatory, urogenital, & nervous systems. Compare the functions of certain organs in a fetal mammal with those of an adult mammal.

The gall bladder sends bile to the duodenum through the bile duct. The gall bladder can be found on the dorsal side of the right lobe of the liver. SBI 3U ANIMALS : STRUCTURE AND FUNCTION STRAND Fetal Pig Dissection Animals used for scientific research and dissection help us to understand our own bodies and how they function in health and disease. The fetal pig will be used as a representative mammal. As a fetus, the pig receives nutrients and oxygen from its mother through the umbilical cord.

Why is the liver large in a fetal pig? The fetus also uses the umbilical cord to dispose of any wastes left in his/her body. State the function of the following organs: Liver : The liver is the largest organ in the body and produces many enzymes and bile, which is stored in the gall bladder and contains bile salts that break down fat globules.

Duodenum - The beginning portion of the small intestine; it is C-shaped and runs from the stomach to the jejunum. Epiglottis - The thin elastic cartilaginous structure located at the root of the tongue that folds over the glottis to prevent food and liquid from entering the trachea during the act of swallowing. Produces digestive enzymes and delivers them through the pancreatic duct and duodenum jejunum Responsible for the majority of nutrient absorption and reabsorption of water. Internal anatomy of fetal pig: Description: The liver is the largest organ of the abdominal cavity, one of its many functions is to secrete bile which helps carry away waste and break down fats in the small intestine.

Small intestine: Absorbs 90% of the nutrients from the food we eat. Very long, but SMALL in diameter Duodenum: receives chyme (Partially digested food) from stomach. Enzymes form the pancreas, liver, and gallbladder mix here for chemical digestion Jejunum: middle section Ileum: where remaining nutrients are absorbed Large intestine:

Description: The small intestine is divided intro three regions: the duodenum, jejunum, and the ileum. 90% of the digestion and absorption of food occurs here. Its primary purpose is to absorb nutrients and minerals from food. The large intestine is where the other 10% of digestion occurs; its primary purpose is to absorb water from the remaining food. The duodenum is approximately 12 inches long and is the portion of the small intestine that ducts from the pancreas and the liver (gall bladder).

a blind pouch which forms at the junction of the small and large intestine. The main functions of it are to absorb fluids and salts that remain after completion of intestinal digestion and absorption and to mix its contents with a lubricating substance, mucus Internal anatomy of fetal pig: Description: The liver is the largest organ of the abdominal cavity, one of its many functions is to secrete bile which helps carry away waste and break down fats in the small intestine.

Examine organs in the abdominal cavity with the fetal pig positioned with its ventral side up. You might wish to remove some of the side walls of the body cavity to make observations easier. Figure 50.1 Salivary glands of a fetal pig, lateral view.

The majority are placental mammals in which the developing young, or fetus, grows inside the female's uterus while attached to a membrane called the placenta. 2009-02-03 2015-11-01 2014-04-25 Wiki User.
