Explain how TWO 2 different structural features can be used

Explain how TWO (2) different structural features can be used to discriminate between the three types of muscles. (2 marks)

Three types of muscles found in the human body are:

1)Skeletal muscle

2)Smooth

3)Cardiac

FUNCTION OF MUSCLES:

1)Regulate organs

2)Help us to move and maintain posture

FUNCTIONS OF SKELETAL MUSCLE TISSUE

FUNCTIONS OF CARDIAC MUSCLE

Pumping of blood through the heart: Alternate contraction and relaxation of cardiac muscle pumps

FUNCTIONS OF SMOOTH MUSCLE TISSUE

Smooth muscle also contributes to moving fluids through the body and to the elimination of indigestible matter from the gastrointestinal system
