Respiratory System


  • Heart Lung Block (HTLB): Heart with pericardium, lungs, esophagus, trachea, and larynx.
  • Heart Lung Block with Pleural Membrane (HTLBPM): Heart with pericardium, lungs with intact pleural membrane (a few nicks may exist in the pleural membrane), esophagus, trachea, and larynx.
  • Lung Set (LUS):  Lung set with trachea and larynx attached.
  • Lung Set with Pleural Membrane (LUSPM): Lung set with pleural membrane intact.  Some small cuts will be present in the membrane.  Trachea and larynx are attached.
  • Trachea to the Primary Bifurcation (TR1): The trachea with the larynx and the primary bifurcation (each bronchus measures 3-4” in length).  The lung tissue is removed.
  • Trachea to the Secondary Bifurcations (TR2): The trachea with the larynx and the primary and secondary bifurcations with lung tissue removed.  The harvested secondary bronchus measure approximately 1”.
  • Trachea to Primary Bifurcation with Esophagus (TR1ES): The trachea with the larynx and esophagus attached is harvested down to the primary bifurcation of the bronchus.

The Value of Animal Growth Charts in Biomedical Research

Our porcine growth chart allows clients to know the expected rate (average daily gain) of growth over time of our Yorkshire cross bred swine herd at all ages.
