Find the trachea, a large air tube that lies anterior to the lungs. The trachea is easy to identify because of the cartilaginous rings that help keep it form collapsing as the animal inhales and
Use this guide to help you dissect a preserved fetal pig, or just look at the labeled pictures to get an idea of what the organs look like. If you do the dissection yourself, you will need dissection pans and dissection tools, or buy our complete Fetal Pig Dissection Kit.
Learning Objectives. Identify external urogenital structures of the male and female fetal pig. Successfully complete dissection of the fetal pig. Identify, on your fetal pig, each structure from the labeled photographs.
• Trachea – extending up from the lungs is the ridged ‘windpipe,’ or trachea. • Larynx – at the top of the throat the trachea bulges out into the larynx, or voice box.
Locate the epiglottis, a cone-shaped structure at the back of the mouth, a flap of skin helps to close this opening when a pig swallows. The pharynx is the cavity in the back of the mouth – it is the junction for food (esophagus) and air (trachea). Gestation for the fetal pig is 112-115 days.
