### Anatomical Dissection of a Fetal Pig

The following diagram illustrates the dissection and external anatomy of a fetal pig, commonly used in educational settings for the study of mammalian anatomy. The labeled diagram provides a systematic approach to identify and understand the anatomical features of the pig.

1. **Head and Oral Cavity**: This section includes the snout, mouth, and tongue. It is essential for examining the dental formula and understanding the initial stages of the digestive system.

2. **Nasopharynx**: Located towards the back of the mouth, this area connects the nasal passages to the throat and is crucial for respiratory studies.

3. **Esophagus**: A muscular tube that conveys food from the mouth to the stomach. This element is significant for studying the digestive tract's initial phase.

4. **Heart**: Central to the circulatory system, the heart's structure and function are key points of study, including the four chambers and associated blood vessels.

5. **Thoracic Cavity**: This includes the rib cage and protects vital organs such as the heart and lungs. It is central to understanding respiratory and circulatory systems.

6. **Liver**: A large, lobed organ involved in numerous metabolic processes, including detoxification, protein synthesis, and the production of biochemicals necessary for digestion.

7. **Stomach**: Part of the digestive tract where food is broken down by gastric juices. It is crucial for studying the mechanisms of digestion.

8. **Small Intestine**: Where most of the digestion and absorption of nutrients occurs. This section is essential for understanding nutrient processing.

9. **Kidneys**: Paired organs that filter blood to produce urine, playing a critical role in the body's waste management system and homeostasis.

10. **Umbilical Cord**: This structure links the developing fetus to the placenta, responsible for nutrient intake, waste elimination, and gas exchange via the mother’s bloodstream.

11. **Lungs**: Organs that enable breathing by facilitating gas exchange with the blood. They are pivotal in the study of the respiratory system.

This diagram is intended to assist students in pinpointing and identifying each significant organ and structure within the fetal pig, promoting a hands-on learning experience in mammalian anatomy. Understanding this anatomical layout not only reveals the interconnected nature of bodily systems but also prepares students for more advanced studies in biology and medicine.
