Answers
Answer:
To observe the internal structures of the heart of any mammal, we have to follow the below-given procedure :
1. First of all, we have to locate the given heart of mammal in a dissection pan. It must be planed in such a manner that the end which is pointed is towards us.
2. This pointed terminal is called Apex.
3. Position the left as well as right auricles of the heart in a proper way in the dissection pan.
Position the mammalian heart on your dissection pan such that the pointed end is towards you and the wide end is toward the top of the pan.Use the model of the heart and the diagrams to help with your identification.The pointed tip is called the apex and the top of the heart is called the base. Orient the heart with the right and left auricles pointing upwards in the dissection pan.
