  1. Super Fast Body Systems

    A quick overview of body systems and how they work together…
  2. Levels of Organization Molecules (like DNA and proteins) Organelles Cells Tissues Organs Organ Systems Organism Populations Communities
  3. Four Major Tissue Types All of the organ systems are made up of just four TYPES of tissues Epithelial tissue-secrete and absorb (line organs, skin) Connective tissue-living cell/nonliving matrix (bone, blood, adipose, and white fibrous) Muscle tissue-contraction for movement (cardiac/heart, skeletal/biceps, smooth/organs) Nervous tissue-stimulus...communication (nerves, brain)
  4. What is/are the function(s) of the various organ systems…how do they fit together? Integunmunintary Skeletal System Muscular System Circulatory System Respiratory System Digestive System Excretory System Immune System Nervous System Endocrine System Reproductive System
  5. The Skeletal System The bones of the body make up the skeletal system (206 bones in adults) FUNCTION: Bones provide protection for internal organs and work with muscles to enable movement
  6. Muscular System Although bones allow for movement, they couldn’t do so without the muscular system Your body has over 600 muscles All muscles are specialized for contraction/movement
  7. Digestive System Mouth, esophagus, stomach, small and large intestines…helps break down food we eat for the nutrients they contain. The liver, salivary glands, pancreas and gall bladder all aid in digestion too (secrete enzymes/hormones)
  8. Excretory System What goes in must come out…excess materials are excreted (exit) our bodies in various ways. We sweat (skin) removing excess water and salts We breathe out carbon dioxide (lungs) We filter blood and remove excess water and salt (kidneys, bladder) We remove nutrients and water from our food and discard the rest (large intestine/colon)
  9. Circulatory System Blood must get around our bodies to carry nutrients and oxygen to our tissues and to carry wastes away… Heart, arteries, veins, capillaries Heart=pump Arteries=carry blood away from the heart Veins=carry blood to the heart Capillaries=in between oxygen/carbon dioxide exchange
  10. Respiratory System To get oxygen in and carbon dioxide out…
  11. Integunmunintary System Hair, skin, and nails… Protection
  12. Immune System Protects the body from disease causing pathogens. Lymphatic system White blood cells Inflammation
  13. Nervous and Endocrine Systems Communication about environmental stimuli as well as internal stimuli The nervous system uses electrical impulses The endocrine system uses chemical messengers (hormones)
  14. The electrical impulse must travel from one neuron to the next as a chemical signal and then transfer back into an electrical impulse Hormones can cause responses without input from the brain…benefit…speed
  15. Reproductive System The male and female parts of humans that allow the production of genetically variable offspring
  16. How they work together… Muscles (muscular system) receive a nerve impulse (nervous system), which causes them to contract… They are attached to bones (skeletal system) in opposing pairs Connective tissues (skeletal system) called tendons connect the muscles to the bones
  17. Some muscles help us get nutrients…and oxygen… Smooth muscles (muscular system) in our espophagus, stomach, and intestines help move food through our digestive system…they know to contract because your autonomic nervous system tells them to…and hormones (endocrine system) in your blood know if you have enough sugar in your blood stream or not! Plus enzymes in your liver help you digest your food (endocrine system)
  18. Our diaphragm (the large muscle between your chest and abdomen) causes our lungs to expand (respiratory system), the oxygen in our lungs enters our blood stream (circulatory system) and we breathe out excess carbon dioxide (excretory system)…it knows to contract because your autonomic nervous system tells it to…
  19. If I touch a hot stove… The nerves (nervous system) in my hand pick up a single that cell damage is occurring in my skin (integunmentary system)… That signal travels to my brain (nervous system), my brain says “crap that’s not good…move your hand!” and that signal travels back down… The muscles (muscular system) in my arm react by pulling my arm up (skeletal system)… If damage has been done, my immune system fights off any invading pathogens while the wound heals by providing platelets and white blood cells from your circulatory system
