Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.

The questions has missed the multiple options. The options are as follows:
(a) organ, organ system, cellular, chemical, tissue, organismal; (b) chemical, cellular, tissue, organismal, organ, organ system; (c) chemical, cellular, tissue, organ, organ system, organismal; (d) organismal, organ system, organ, tissue, cellular, chemical.
Answer:
Option (c).
Explanation:
The evolution of the complex organisms take several billion years. The evolution of the organisms starts from the basic level and then move to the complex forms.
The hierarchy determines the level of the organization. Cell is the basic level of organization. The cells are formed by the union of chemicals. The cell combine together to form tissue. Tissue combines together to form the organ then the organ system and finally the whole organisms.
Thus, the correct answer is option (c).
