1. Our heart is made up of muscle tissues (smooth and cardiac muscles). Explain how these muscles work in our heart and how to take care of it to sustain life. For 8 points
The human body contains three different kinds of muscle tissue: skeletal, smooth, and cardiac. Only cardiac muscle tissue, comprising cells called myocytes, is present in the heart.
Explanation:
The heart consists mostly of cardiac muscle cells (or myocardium). The outstanding characteristics of the action of the heart are its contractility, which is the basis for its pumping action, and the rhythmicity of the contraction.
