  1. The Dissection of the Fetal Pig 1. External Anatomy 2. Opening of the Body Cavity 3. The Thoracic Cavity A. Respiratory System B. Circulatory System 4. The Abdominal Cavity A. Digestive System B. Excretory System C. Reproductive System

  2. External AnatomyIdentify the structures in the pig.

  3. Opening of the Body Cavity

  4. The Thoracic Cavity (Circulatory/Respiratory) • Identify the heart (major veins/arteries and parts), trachea, lungs and diaphragm in the pig.

  5. The Thoracic Cavity (Respiratory) Bronchi Lungs

  6. The Thoracic Cavity (Circulatory) Vena Cava Aorta Rt. Atrium Lft. Atrium Rt. Ventricle Lft. Ventricle Coronary artery

  7. The Abdominal Cavity (Digestive) Identify the organs in the digestive system

  8. The Abdominal Cavity (Digestive) Gall Bladder Liver Stomach Pancreas Spleen Large and Small Intestines

  9. The Abdominal Cavity (Excretory) Kidney Kidney Ureter Ureter Urinary Bladder

  10. The Abdominal Cavity (Reproductive) • Identify MALE reproductive organs

  11. The Abdominal Cavity (Reproductive) Genital opening Penis Epididymis Vas deferens Testicle Testicle

  12. The Abdominal Cavity (Reproductive) • Identify the FEMALE reproductive organs

  13. The Abdominal Cavity (Reproductive) Ovary Ovary Uterus Cervix Urethra Vagina

  14. Pig Interviews You will be required to meet 1-on-1 with me for an interview with your pig. You are responsible for knowing the functions/structures in each body system.

  15. Lab Dissection Roles 1. Principal Investigator • You are in charge of the team. • You read the directions as the team works on • the lab. • You help the Materials Manager if needed • You will lead discussions and ask questions. 2. Maintenance Director • You are in charge of keeping the work station clean and orderly during the lab. • You are responsible for group safety. • You pick up the lab materials. • You are in charge of clean-up at the end of lab – Return the materials 3. Recorder/Reporter • You are in charge of recording data during the lab. • You make sure the group members record data in their lab guides. • You monitor the time and keep the group moving 4. Materials Manager • You set up the investigations. • You conduct the dissection as the Principal Investigator reads the instructions.

  16. Dissections continued… • All group members are allowed to touch and handle the specimen • You will be in groups of 3 or 4 • Assign roles within you group • PLEASE FOLLOW ALL DIRECTIONS • Head to the back with your group and wait for more instructions
