Study Notes

The Human Body Systems

Digestive System

  • Takes in food through ingestion
  • Digests food into smaller molecules and absorbs nutrients
  • Removes undigestable food from the body as feces
  • Works with:
    • Circulatory system to absorb and deliver nutrients to cells
    • Muscular system to control contractions of digestive organs
    • Nervous system to maintain homeostasis and trigger appetite

Circulatory System

  • Transports materials to and from cells
  • Works with:
    • Respiratory system to deliver oxygen to cells and remove carbon dioxide
    • Excretory system to filter waste out of blood
    • Integumentary system to remove excretory waste
    • Muscular system to control pumping of blood

Excretory System

  • Removes waste products from cellular metabolism
  • Filters blood and removes waste
  • Works with:
    • Lungs to remove excretory waste
    • Integumentary system to remove excretory waste
    • Circulatory system to filter waste out of blood
    • Muscular system to control contractions of excretory organs

Respiratory System

  • Takes in oxygen and removes carbon dioxide and water
  • Works with:
    • Circulatory system to deliver oxygen to cells and remove carbon dioxide
    • Excretory system to remove waste
    • Nervous system to control breathing
    • Muscular system to control diaphragm contractions

Skeletal System

  • Protects organs
  • Provides shape and support
  • Stores materials (fats, minerals)
  • Produces blood cells
  • Allows movement
  • Works with:
    • Muscular system to allow movement
    • Circulatory system to produce blood cells
    • Immune system to produce white blood cells

Muscular System

  • Allows movement by contracting
  • Works with:
    • Skeletal system to allow movement
    • Digestive system to control contractions of digestive organs
    • Respiratory system to control diaphragm contractions
    • Circulatory system to control pumping of blood
    • Nervous system to control muscle contractions

Endocrine System

  • Regulates body activities using hormones
  • Works with:
    • Circulatory system to transport hormones to target organs
    • Nervous system to maintain homeostasis and control hormone release
    • Reproductive system to control hormone production

Immune System

  • Fights off foreign invaders in the body
  • Works with:
    • Circulatory system to transport white blood cells to fight invaders
    • Lymphatic system to hold white blood cells to fight pathogens
    • Skeletal system to produce white blood cells in bone marrow
    • Integumentary system to prevent invaders from entering the body

Integumentary System

  • Protects against infection and regulates body temperature
  • Removes excretory waste
  • Works with:
    • Excretory system to remove waste
    • Nervous system to control body temperature
    • Immune system to prevent invaders from entering the body

Lymphatic System

  • Stores and carries white blood cells to fight disease
  • Collects excess fluid and returns it to blood
  • Works with:
    • Immune system to hold white blood cells to fight pathogens
    • Circulatory system to transport materials to and from cells

Reproductive System

  • Allows organisms to reproduce
  • Works with:
    • Endocrine system to control hormone production
    • Muscular system to control contractions of reproductive organs
