How to dissect the heart
- Open up Cranial + Caudal vena cavae
- Go into right atrium and enter the RV with youre finger, point scizzor to your finger as close to the septum you can, and make a longit. ins. cut along sulcus interventricularis paraconalis. Pay attention to the trabecula septomarginalis.
- Open tr. pulmonalis, Enter youre finger into the left ventricle. Feel the two papilary m. and cut in between. extend cut till the left auricle
