![]() License: Public domainAnatomical Directions. Muscles: Muscles facilitate movement and contribute to the overall structure of the body.Bones: The skeleton provides support and protection for internal organs.Nerves: Extend throughout the body, transmitting signals.Brain and Spinal Cord: Control and coordinate various body functions. ![]() On males, the opening is located near the umbilical cord. On females, this opening is located near the anus. Determine the sex of your pig by looking for the urogenital opening. Uterine horns are present internally in females Fetal Pig Dissection: External Anatomy External Anatomy 1.In females, the urogenital opening is ventral to anus, and has genital papilla.In males, the scrotal sac is ventral to anus and contains the testes.Testes or Ovaries: Depending on gender, fetal pigs have either testes (male) or ovaries (female).Initial Inspection: Examine the external anatomy of the fetal pig, noting key features such as size, shape, and fur texture (if applicable). Ensure all dissecting tools are sterilized and ready for use. Set up the dissection tray in a well-ventilated area. Urinary Bladder: Stores urine before excretion. Preparation: Put on disposable gloves and protective apron.Kidneys: Filter blood and produce urine.Blood Vessels: Arteries carry oxygenated blood away from the heart, while veins return deoxygenated blood to the heart.Vena cava: Located next to the aorta, returns blood to the heart.Aorta: Large artery that leaves the heart and supplies blood to the body.Heart: The heart is a four-chambered organ (two atria, two ventricles) that pumps blood.Lungs: Responsible for gas exchange (oxygen in, carbon dioxide out).Epiglottis: flap that closes during swallowing to prevent food from entering airway.Nose and Trachea: Air enters through the nose and travels down the trachea.Pancreas: located below the stomach, secretes insulin.Gallbladder is underneath the liver and stores bile connect to liver via common bile duct.Liver has many lobes and located just below the diaphragm, produces bile and breaks down substances.Cecum: pouch at the junction of the ileum and colon.Large Intestine (colon): Involved in water absorption and feces formation.Small Intestine: Absorbs nutrients from digested food consists of three sections: duodenum, jejunum, and ileum.There are several reasons for this, including that pigs, like humans, are mammals. Stomach: Responsible for the initial digestion of food. Along with frogs and earthworms, fetal pigs are among the most common animals used in classroom dissection.Esophagus: Connects the mouth to the stomach.Mouth: The mouth contains teeth for grinding food.Limbs: Four limbs with hooves are present, and the skeletal structure is visible.Eyes and Ears: Fetal pigs have well-developed eyes and ears.Size and Weight: Fetal pigs used in dissection are typically around 12-16 inches in length and weigh a few pounds.Here's an overview of key anatomical features in a fetal pig: The anatomy of a fetal pig is similar to that of other mammals, including humans. Studying the anatomy of a fetal pig through dissection allows students to explore these systems in detail and gain a better understanding of mammalian anatomy, including the similarities and differences with human anatomy. You can order fetal pigs from biological supply companies or from Amazon. This versatility enhances the educational value of the dissectio The colou r of the liver is dark pink, it is very meaty/thick. Describe: Location & Relationship between appearance & functio n. Their stage of development is also suitable for observing various organ systems.įetal pig dissection allows for the exploration of multiple organ systems, including cardiovascular, respiratory, digestive, and reproductive systems. Unit 4 Pig Lab Examining the Systems of a Fetal Pig. This accessibility makes them a practical choice for hands-on dissection activities in educational settings.įetal pigs are large enough to allow for detailed study of internal structures, yet small enough to be manageable for dissection in a classroom setting. They are relatively affordable and easily obtainable for educational purposes. Studying fetal pig anatomy provides valuable insights into human anatomy, allowing students to understand structures and systems in a living organism. Exploring Anatomy: A Comprehensive Guide to Fetal Pig Dissection Techniques and Observationsįetal pigs share many anatomical similarities with humans.
