Fetal Pig Dissection

Fetal pig external structures include

• Umbilical cord - Connect fetus to mother, flow of nutrients in, waste out

• Mammary papilla (present in both male/female) - Nourish young

• Urogenital opening - Expulsion of waste and productive fluids

Mouth cavity and pharynx include

• Hard palate - separates nasal cavity from oral cavity; food manipulation

• Soft palate - separates nasal cavity from oral cavity; food manipulation

• Larynx - voice box; connect pharynx and trachea

• Esophagus - connect pharynx to stomach

• Epiglottis - Prevent food and liquid from entering airways

• Thymus - T cell maturation

• Trachea - conduct air to and from lungs

• Thyroid gland - Oval gland and responsible for hormones in body

Fetal pig thoracic & abdominal cavities include

• Lungs - respiration

• Heart - Circulates of blood

• Diaphragm - Contraction expands lungs for respiration

• Spleen - Site of immune cell interactions

• Umbilical vein - carries oxygenated blood from placenta to fetus

• umbilical arteries - carries deoxygenated blood from fetus to placenta

• Kidneys - control volume and composition of blood

In the thoracic cavity are the following:

• Heart

• Lungs

• Diaphragm

• Pericardium - membrane that surrounds and protects the heart
