reasons:
Three types of proteins form myofibrils: 

1)contractile,
2) regulatory,
3)structural.

 Contractile proteins generate force formuscle contraction.

The twocontractile proteins in myofibrils are actin which is part of thin filament and myosin, which is part of the thick filament

(ii) reasons :

*These muscles push materials like food or blood through organs.

*Unlike skeletal muscle, smooth muscle can never be under your control. 

*Cardiac muscle is also an involuntary muscle, found only in the heart.

* The cardiac muscle fibers all contract together, generating enough force to push blood throughout the body.
