Final answer:
Cardiac tissue should be kept moist and between 0°C to 8°C during the dissection process to prevent deterioration.
Step-by-step explanation:
To prevent possible cellular tissue and matrix deterioration during the dissection process, cardiac tissue should be kept moist and maintained at a temperature between 0°C to 8°C (32°F to 46°F). This ensures that the tissue does not undergo significant degradation and maintains its structure and functionality.
