It is so large because it is still a fetus and it will shrink as the big matures. The vagina, and the vaginal vestibule, lye just behind the urethra were viewed. Begin to cut on line 6 on the left atrium where cut 4 began. This concluded our dissection for the evening. It is purplish in colour and varies in size in different individuals, but it is usually about 120mm C What is the function of the mesentery? Absorption of electrolytes and water. The format for this will differ from that of the osteoporosis lab report because the dissection is used as an opportunity to review structure and function for the major systems rather than to test a hypothesis and draw a conclusion.
These contractions ensure the regular flow of blood through the heart. The role of the blood is to supply organism with oxygen and nutrients. Carolina produces the finest preserved sheep organs using Carolina's Perfect solution®, a unique, revolutionary fixative that dramatically improves the quality of classroom dissection. Next, we used our fingers as a guide to cut through the ribs. Physiological and Anatomical Similarities of the Human and Fetal Pig Body Abstract Through the dissection of the fetal pig, we were able to compare and contrast the structure and functions of the organs to those of a human. We observe how the diaphragm attaches to the body wall, and separates the abdominal cavity from the lungs, and heart.
Extend this cut around and through the pulmonary artery upward on the aorta to the right of cut 5. Inside the lungs, the bronchi branch out many times, like a tree, to form smaller bronchi and then thousands of tiny tubes. Cut on line 5 across the middle of the left ventricle into the aorta. Anatomy, Biology, Blood 556 Words 6 Pages tapings before taking down the readings and make sure that we avoid parallax error by ensuring our eyes is leveled with the tapings when recording the readings. Conclusion 1 Trace the path of blood from the right atrium to the aorta. Spleen — The spleen is formed by reticular and lymphatic tissue and is the largest lymph organ.
With tweezers, carefully lift the resulting flap to expose the structures underneath. The first part of our dissection involved reviewing the masseter muscle structure. . Locate the following external features and be able to identify on the dissection quiz: renal capsule hilum renal artery renal vein ureter d. We Lift the right lobe of the fetal pig and identified the gallbladder. They are similar except for the pancreas and the adrenal glands.
The blood flows to the lungs and comes back to the heart through pulmonary veins to the left atrium. In the fetal pig, the adrenal glands are medial to each kidney and inferior to the pancreas rather than atop to kidneys and superior to the pancreas as in humans. More than 500 vital functions have been identified with the liver. To predict the solubility of an unknown Group 2A salt based on the determinations made. The diaphragm muscle was located meeting resistance on both sides at the bass of the abdomen where diaphragm separates the lower body region. Once we pill off the layer of skin we located the masseter muscle plucking, and pilling at the structure for closer view.
Everything has a purpose in the lab. Transitional Top cells appear to be larger, round, and have 2 nuclei. To reach every part of the body, blood is distributed by artery tissues. Materials: Safety goggles String Dissecting pins Lab apron Scalpel Scissors Dissecting gloves Hand lens Ruler Preserved Pig Dissecting Tray Forceps and probe Observations Using a ruler, measure the length of the pig from the snout to the tail. The liver processes this blood and breaks down the nutrients and drugs in the blood into forms that are easier to use for the rest of the body.
These substances enter the tubules, in which tubular reabsorption occurs. Cartilaginous rings conveys inhaled air from the larynx to the bronchi G Make labelled diagrams of the following: Hypothesis Obesity is one of the factors influencing increase of systolic and diastolic blood pressure. D Why does the left ventricle contain more muscle than the right ventricle? Then, Locate a diagonal deposit of fat along the lower two-thirds of the heart. The heart is a muscle that pumps oxygenated blood and nutrients throughout the body. We dissected the pig so that we should see the skeletal and organ structures that we learned about in class.
We did not know that a mammal's kidney was really big. The spleen lies in the left hypochondriac region of the abdominal cavity between the fundus of the stomach and the diaphragm. All of the blood leaving the stomach and intestines passes through the liver. The purpose of a base coat is to help the polish stick to your nails more easily. Is it rather due to unhealthy lifestyle or inappropriate diet? These two cuts allowed us to spread open the abdominal cavity. Therefore, secretion of renin causes a blood pressure increase. What is the smooth semitransparent membrane that adheres tightly to the outer surface of the kidney? Background Information When painting nails, some manicurists use a base coat before applying the polish.
We also identitified the sex of our fetal pig, and upon observation at the base of the umbilical cord we determined the sex was a male. What is the cavity within the kidney that is continuous with the ureter? We started our observations around the head, looking at the mouth, ears, eyes, and snout. In addition to this, the fetal pig dissection helps students better interpret the relative position and sizes of organs, as well relation between organ and organ system. This concluded our dissection plan for the night. Also, through this experiment, students know some basic indexes to assess the efficiency of pumps used.
This concluded our dissection for the evening. Connective tissue and a basement membrane Stratified Cuboidal online Double layer of squarelike cells, each having. In lab we received a fetal pig for dissection to be done over five lab sessions. In what chambers does systemic circulation begin and end? Aorta, Aortic arch, Arteries of the thorax 941 Words 3 Pages Roy Levin Bio 11 Lab Dr. Pull fat bodies away from their attachment to the kidneys 6. Bile is a digestive liquid continually secreted by the liver. The rectum and anal opening of the pig was observed.
