Part A:
Organization in Multicellular Organisms and Anatomical Terms

During Lab 10 and 11 you will begin to familiarize yourself with the anatomy of various organs and organ systems.
During lab 12 you will familiarize yourself with additional organs and organ systems and then dissect a fetal pig and locate all the organs you have been studying.
We use a pig for these dissections because their internal anatomy is so similar to ours.

• Use the "Organization in Multicellular Organisms" and "Anatomical Terms and Directions" sections to help you answer either the pre-lab questions or the questions in Part A of the Lab Report.

Part B:
External Anatomy

• Using the Image provided below and in the lab report state the letter associated with the external structures listed in Part B of the Lab Report.

Part B: Image shows a lateral view of a fetal pig. The Letter A is pointing to the pig's back. On the pig’s head the letter B is pointing to flaps on the top and sides of the head. The letter C is pointing to the head end. The letter E is pointing to one of two small openings at the most anterior part of the head (on the snout). The letter F is pointing a fleshy, muscular organ with many small bumps protruding from the mouth. On the pig’s trunk the letter D is pointing to a joint distal to the shoulder. The letter G is point to a joint found distal to the letter D. the letter I is pointing to a cord on the fetal pig’s ventral surface. The letter H is pointing to the belly surface of the fetal pig. The letter M is lying on the surface facing the viewer. The letter K is pointing to a joint distal to the hip The letter J is pointing to a joint distal to letter K. The Letter L is pointing to the pigs hind surface.

• Use the image above to answer questions 1-13 in the Lab Report/Post Lab Questions.

Part B: This Image shows two fetal pigs. On the left is a Male, on the right is a Female. Between them one structure has been enlarged for a clearer view. In the image of the Male the letter A pointing to many circular structures on either side of the umbilical cord on the pig’s ventral surface. These can also be seen in the female. The letter B is pointing to an opening posterior to the umbilical cord and anterior to the anus. The letter C is pointing to a sac between the male pig’s hind legs. Enlarged in the center of the image is a cord still attacked to the fetal pig’s ventral surface. In the enlarged area the letter D is pointing to one of two small circles and the letter E is pointing to one larger, irregular shaped opening. In the image of the Female pig the letter F is pointing to the cord itself and the letter G is pointing to a small raised piece of flesh anterior to the anus.

• Use the image above to answer questions 14-20 in the Lab Report/Post Lab Questions.

Part C:
Internal Anatomy

• Use the models provided in the lab to locate the structures listed in Part C of the Lab Report.
• Have your instructor verify that you have correctly identified each of these listed structures.

• Using the images below Identify the structures listed in Part C of the Lab Report.

• Use the image above to answer questions 37-40 in the Lab Report/Post Lab Questions.

• Use the image above to answer questions 41-47 in the Lab Report/Post Lab Questions.

Part D:
Nutrition and Analysis of Food labels.

Using the Food labels provided in lab answer questions in Part D of the Lab Report.
NOTE - the image below may be the food labels provided by your instructor, or they may provide you with different labels. Consult your lab instructor before answering these questions.

Part E:
Homeostasis, Balance & Disease

• You will be working in groups for this part ofthe lab. Each group will be assigned one of the following case studies.• Use the information in the case study and in the table in the lab manual todiagnose the patient’s disease or disorder.

‍Case Study #1: • A 40-year-old female has been very thirsty over the last two months. She has also been urinating more during the same period. In addition, she states that she has been eating more lately. A blood test reveals that her blood sugar level is high. What condition may be causing the woman to experience these signs and symptoms?

‍Case Study #2:• A 20-year-old male is brought to the emergency room of a hospital. He had been hiking with his friends in the mountains all day, where the temperature outdoors was 92oF. His body temperature in the emergency room was recorded as 101 oF. He seems confused and asks to drink a great deal of water. He has not urinated all day. What condition may be causing the young man to feel this way?

‍Case Study #3:• A 60-year-old female goes to her doctor complaining of “puffiness”. Her ankles and face look swollen. Her blood pressure is low. She recently had a kidney infection with cloudy urine. What condition may be causing the woman to feel this way?

‍Case Study #4:• A 25-year-old female who is in her 7th month of pregnancy, goes to her doctor complaining of “wetting her pants”. What condition may be causing the woman to experience this condition?

‍Case Study #5:• A 32-year-old male goes to the emergency room of a hospital complaining of headache, skin blisters, fever and chills. He states he as had sexual intercourse with 10 different individuals in the last two months. What may be causing all of this in this patient?
