Answer:
3 specific tissue types predominant in the heart are -Cardiac muscle , Nervous tissue , Connective tissue .
Explanation:
1. Cardiac muscle - They help in pumping blood to circulation. When they contract the blood is forced out into systemic and pulmonary circulation.
2. Nervous tissue - they help in regulation of heart function. They generate, coordinate and conduct electrical impulse that regulate heart contraction
3. Connective tissue - blood vessels and pericardium. The pericardium surrounds heart and has pericardial fluid that acts as shock absorber and thus prevent damage to heart. The blood vessels i.e. coronary artery and veins supply blood to muscles of heart.
