  1. Organ SystemsWeek 1 LPA 2013-2014 Standard 3

  2. Monday Objective • I will describe the structure and function of animal organs.

  3. Bell work • Create vocabulary flashcards for the following terms: • Cell • Tissue • Organ • Organ system • Organism • Homeostasis

  4. Organization of Living Things • Levels of Organization • Cell • Tissue • Organ • Organ System • Organism

  5. Review • Define the following • Atom • Molecules

  6. Cells • Basic unit of structure and function • 8 types of specialized cells in humans • Blood cells • Surface skin cells • Bone cells • Epithelial and Goblet cells • Neuron • Cardiac muscle cell • Skeletal muscle cell • Smooth muscle cell

  7. Tissue • A group of similar cells that work together. • 4 main types of tissue. • Nervous – sense ________ and________ signals. • Epithelial – line the ____________ of the body. • Connective – _______ and ______ other tissues. • Muscle -- _______ and ________ movement.

  8. Organ • Two or more types of tissues that work together to do the same job.

  9. Organ System • A group of organs that work together to carry out a complex overall function.

  10. Organism • All of the organs and organ systems working together to maintain homeostasis. • Homeostasis – the process in which organ systems work to maintain a stable internal environment • Nutrition • pH • Temperature • Molecule concentrations

  11. Death • Death is the result of the organism’s failure to maintain homeostasis.

  12. Monday Objective • I will describe the structure and function of animal organs.

  13. Homework • Answer questions #1-7 on page 148. • Read pages 149-170.

  14. Tuesday Objective • I will relate the structure of organs to their function.

  15. Bell work • Complete the data table comparing types of cells and tissues.

  16. Reading Questions • What questions do you have as a result of your reading?

  17. Organ Systems • Purpose: maintain _____________. • Basic Systems: • Skeletal • Muscular • Integumentary • Endocrine • Circulatory • Respiratory • Digestive • Urinary • Lymphatic • Nervous • Reproductive • Immune

  18. Skeletal System • Functions • Maintain __________ and _________ of the body. • ___________ internal organs. • Provide ___________ surfaces for ________. • Produce ___________ cells. • Store __________ . • Maintain ____________ homeostasis.

  19. Bony Tissue • Compact Bone • Spongy Bone • Periosteum

  20. Muscular System • Three types: • Smooth muscles – form the walls of internal organs. • Involuntary • Contracts (squeezes) • Cardiac Muscles – form the walls of the heart. • Involuntary • Contain a large number of mitochondria to produce ATP for energy. • Skeletal Muscles – attached to bone. • Voluntary • Most common type of muscle in humans.

  21. Integumentary System • The Skin!! • Function = provide a protective covering for the body and help the body maintain homeostasis • Two layers • Dermis - • Epidermis -

  22. Nervous System • Carries __________ messages throughout the body. • Two types of Nerve cells • Neurons – structural and functional units • Glial cell – provide support and nutrition.

  23. Nervous System • Two Divisions: • CNS – Central Nervous System • Brain • Spinal cord • PNS – Peripheral Nervous System • All the nervous tissue outside the CNS

  24. Endocrine System • A system of glands that release chemical messages into the bloodstream. • Hormone – the chemical released by a gland • Hormones act much slower than the nervous system.

  25. Circulatory System • Allows the transport of materials from one place to another. • The blood carries _____________, ___________, ___________, and _________. • Three main components: • Heart • Blood vessels • Blood

  26. The Heart • Made of cardiac muscle which Pump blood through blood vessels through rhythmic contraction. • Four Chambers • Two Atria • Two Ventricles

  27. Blood Vessels • A network throughout the body to transport blood to all the body cells. • Arteries – • Veins – • Capillaries –

  28. Respiratory System • Exchange of gases between the body and the outside air. • Two parts: • Air into and out of lungs. • Blood carries oxygen to cells and carbon dioxide away from cells.

  29. Respiration vs Cellular Respiration • Respiration = the exchange of ___________. • Cellular Respiration = the process by which cells obtain _____________ by “burning” glucose. • Cellular Respiration uses ____________ and releases ___________ ___________.

  30. Respiratory System • Main Organ is the ___________. • The lungs resemble an upside down tree and are lined with __________. (Draw on board) • The mucus keeps the tissue _______ for gas exchange and __________ small foreign particles.
