The document outlines the three types of muscles in the human body: skeletal, smooth, and cardiac. It explains that structural features can be used to discriminate between these muscle types based on their functions, such as regulating organs, moving fluids, and pumping blood. Each muscle type has distinct roles, with skeletal muscles aiding in movement, cardiac muscles pumping blood, and smooth muscles facilitating bodily processes.

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