  1. Body Systems Overview

  2. Homeostasis • The process of maintaining stable internal conditions is called homeostasis. • our body systems need to all work together in a coordinated fashion in order to maintain homeostasis

  3. We have 11 Body Systems

  4. Digestive System Function: to break down food particles into simpler molecules so our body can absorb them Structures: mouth, pharynx, esophagus, stomach, small intestine, large intestine, gall bladder, pancreas, & liver

  5. Nervous System Function: coordinates all body activities and is the communication between the body and its environment Structures: brain, spinal cord, & nerves

  6. Immune Function: defense against pathogens & foreign agents Structures: White blood cells, antibodies, bone marrow, lymph nodes

  7. Circulatory System Function: Transports gases (oxygen and carbon dioxide), nutrients, and wastes throughout the body via blood vessels Structures: vessels (arteries, capillaries, veins), heart, & blood

  8. Integumentary System Function: to cover our body and provide it with protection. Structures: epidermis & dermis

  9. Skeletal System Function: supports our body, allows for muscle attachment, protects organs, makes blood cells, and is a storage site Structures: bones

  10. Muscular System Function: allows for voluntary and involuntary movements Structures: muscles

  11. Excretory System Function: help maintain homeostasis of body fluids Structures: kidneys, ureters, bladder, & urethra

  12. Endocrine System Function: to regulate body functions using hormones Structures: glands, & hormones

  13. Respiratory System Function: breathing, allows for gas exchange via the lungs Structures: lungs (bronchi, bronchioles, alveoli), diaphragm, trachea, mouth, nose

  14. Reproductive System Function: to produce gametes that can be used to produce offspring Structures: ovaries, uterus, testes, sperm, eggs
