  • Main organ systems in the human body
    • Endocrine system
    • Respiratory system
    • Muscular system
    • Male reproductive system
    • Female reproductive system
    • Lymphatic system
    • Nervous system
    • Blood circulatory system
    • Digestive system
    • Urinary system
    • Skeletal system
    • Integumentary system
  • Endocrine system
    The endocrine gland secretes hormones. Main function: Coordinates body activities with the nervous system
  • Respiratory system
    Trachea, nose, lungs and diaphragm. Main function: Exchange of oxygen and carbon dioxide gases between the body and the external environment
  • Muscular system
    Skeletal muscles, smooth muscles and cardiac muscles. Main function: Contracts and relaxes to produce movements in different parts of the body
  • Male reproductive system

    Testes, prostate gland and penis. Main function: Produces sperm and male sex hormones
  • Female reproductive system
    Ovary, uterus, Fallopian tube, vagina and cervix. Main function: Produces ovum and female sex hormones
  • Lymphatic system
    Spleen, lymph nodes and lymph vessels. Main function: Maintains balance of bodily fluids and prevents infectious diseases
  • Nervous system
    Brain, spinal cord and peripheral nerves. Main function: Detects and send information in the body, as well as coordinates body activities
  • Blood circulatory system
    Heart, artery, vein and blood capillary. Main function: Transports nutrients, respiratory gases and waste products
  • Digestive system
    Mouth, oesophagus, stomach, liver, pancreas, small intestine and large intestine. Main function: Digests food into a simpler form for easy absorption
  • Urinary system
    Kidney, ureter, urethra and bladder. Main function: Eliminates waste products such as urea and uric acid from the body
  • Skeletal system
    Bone, cartilage, ligament and tendon. Main function: Supports the body, protects the internal organs and provides a base for muscle adhesion
  • Integumentary system
    Skin. Main function: Protects the body from physical injury, infection and dehydration
  • Main plant systems
    • Shoot system
    • Root system
  • Shoot system
    Consists of stems, leaves, shoots, flowers and fruits. Stems and twigs are support systems that support the leaves at the vertical position to allow maximum absorption of sunlight during photosynthesis. Flowers are involved in the pollination process
  • Root system
    Consists of all roots in a plant that function in absorbing water and mineral salts as well as providing support for plants
