muscle system
Muscle System
  • Skeletal Muscles
  • Automatically controlled by the brain:
  • Cardiac Muscles in the heart
  • Smooth Muscles in organ such as

the alimentary canal

antagonistic muscles
Antagonistic Muscles
  • Antagonistic muscles work in pair.
  • The pair of muscles work in an opposite manner to each other
circulatory sy s tem

  • Organ present are oesophagus, stomach and intestines
  • Other organs include liver and pancreas
  • Functions: breakdown and absorption of food ith the help of enzymes
the respiratory s ystem
The respiratory system
  • Organs: lungs, breathing tubes ( trachea, bronchi, bronchioles)
  • Allows gas exchange
excretory system

  • Organs: kidneys and bladder
  • Remove waste such as urea in the form of urine
