  4. Homework Finish Anatomical Sports Assignment– Due Monday 8/27 Agenda Warm-up: Summer HW peer grading Intro to anatomical sports assignment Anatomical sports work time! Warm-Up: Fri. 8/24/18

  5. Peer Grading: Summer HW

  6. Warm-Up: Mon. 8/27/18 Answer: How are the terms ‘anatomy’ and ‘physiology’ distinct from each other? Which 2-3 characteristics of living things do you believe to be most critical to our survival? Explain. Objective: I can use my knowledge of homeostasis and requirements for life to analyze an exercise-induced physiological disturbance.

  7. Homework none Agenda Notes 1.1-1.4 Share-out: Anatomical sports assignment Warm-Up: Mon. 8/27/18

  8. DirectionsAnatomical Sports Share-Out If you are chosen to share-out: it at the front and read it to the class. While reading, do not make any physical motions that might reveal your chosen sport/action! When finished, write ‘Presenter’ next to the appropriate number. If you are in the audience: Give the presenter the silent respect you would want. Determine which sport they are describing and write it next to the appropriate number.

  9. A Case Study.. In 2007, Kati Mori took part in the London Marathon - her fourth, and the hottest on record, with temperatures peaking at 75 F. Conscious of the repeated advice to maintain fluid intake, she took frequent drinks at the water stations along theroute. By the 18th mile, Kati felt bad but was determined to finish, Near the end, she needed help from other runners to stay upright; hours later she was in the hospital, suffering from severe diarrhea, headache, vomiting and increasing confusion, with her legs endlessly mimicking a running motion. "I thought I was still in the marathon," she says. Essential Question: What happened to Kati Mori at the LondonMarathon?

  10. Anatomy is the study of the structure of bodyparts. Physiology is the study of the function of body parts; what they do and how theydo it. Whatisthedifference betweenanatomy and physiology?

  11. Whatisthe relationship between anatomy andphysiology? The structure determines the function, not the other wayaround! Example: Proteins

  12. Movement - self initiated change in position, motion of internalparts Sensitivity/Responsiveness - ability to sense changes andreact Growth - increase in bodysize Reproduction - DNA passed from parents tooffspring Respiration - obtaining oxygen(02) Nutrition/metabolism- Chemically changing (breaking down)food. What are the characteristics ofall livingthings?

  13. Absorption -passage of digested products (food) through membranes and into bodyfluids Circulation - movement of substances throughout the body Assimilation -changing absorbed substances into chemically differentsubstances Excretion - removal ofwastes What are the characteristics ofall livingthings?

  14. Back to the Case Study… Review the list of life processes and consider Kati Mori’s symptoms. Choose three of the processes that you think might be impacted in her situation.

  15. In answer to the dilemma.. Metabolism = all the chemical changes that occur in the body to maintainlife. Ultimately all of these processes requireENERGY How do we obtainenergy?

  16. Bodily needs = food, oxygen, water, heat, pressure. (How long can you live withoutthese?) Thenext dustbowl Drought is the most pressing problem caused by climate change. It receives too little attention, says Joseph Rom.

  17. The longest known record of living without is...... . Food = 21days Oxygen= 25minutes Water = 10days

  18. Warm-Up: Tues. 8/28/18 Answer: What is the main purpose of cellular respiration? Write out the equation (use chemical notation to push yourself). What is the main purpose of photosynthesis? Write out the equation (use chemical notation to push yourself). Objective: I can describe the locations of major body cavities and membranes, and identify key parts of each organ system.

  26. …back to the case study.. Review the information about the body systems from the readingguide Which systems do you think are being impacted in Kati Mori'ssituation?

  27. Warm-Up: Wed. 8/29/18 Answer: (NO WARM-UP SHEETS) Body systems flow chart Objective: I can identify the structure and function of one major body system, and use this knowledge to begin drafting a poster project.

  28. Homework -Body Systems Project – Due Friday 8/31**tentative -Complete Ch. 1 Reading Guide – Due Tuesday 9/4 at start of class Agenda Body Systems Flowchart Body Systems Project work time Warm-Up: Wed. 8/29/18

  29. Answer: Why is it necessary to be in a pressurized cabin when flying at 30,000 feet? HINT: Think about the characteristics of life. When you rub your cold hands together, the friction between them results in heat that warms your hands. Why doesn’t warming friction result during movements of the heart, lungs, and digestive organs? Objective: I can identify the structures and functions of one major body system, and use this knowledge to begin drafting a visual poster and fact sheet. Warm-Up: Thurs. 8/30/18

  30. Homework -Body Systems Project – Due Tuesday 9/4 -Complete Ch. 1 Reading Guide – Due Tuesday 9/4 at start of class Agenda Work time: Body Systems Project Warm-Up: Thurs. 8/30/18

  31. Answer: Which body system are you doing your project on? What are the major functions of this system? What do you still need to do over the weekend to complete your project? Objective: I can describe why homeostasis is important to healthy body function, and identify 1-2 examples of negative and positive feedback. Warm-Up: Friday 8/31/18

  32. Homework -Body Systems Project – Due Tuesday 9/4 by 3 pm -Complete Ch. 1 Reading Guide – Due Tuesday 9/4 at start of class Agenda Notes: Homeostasis Final work time: Body Systems Project Warm-Up: Friday 8/31/18

  33. What is homeostasis? • Describes the body’s ability to maintain stable internal conditions even though the outside world is constantly changing • Indicates a dynamic state of equilibrium, or a balance where internal conditions change and vary within narrow limits • Every organ system works to maintain equilibrium inside the body

  34. ,---- --- - - -· • 3 major mechanisms for homeostatic controlcenter: • (1)Receptor • (2) Controlcenter • (3)Effector How is homeostasis regulated? Stimulates

  35. Homeostasis:Receptor • o The receptor is some type of sensor thatmonitors • and responds to changes in the environment (stimulus) • f1 The receptor responds to the stimulus by sending information (called input) to the control center (brain) • Examplesof receptors can include: temperature receptorsintheskin,glandsintheendocrinesystem, painreceptors, nerves, etc

  36. The control center (brain) determines the set point or level that a variable must be maintainedat o The control center analyzes the information it receives from the receptors and then determines the appropriate response or course of action Homeostasis: ControlCenter Body Chemistry 101 Balance? Biomolecules? Blood Pressure (too high? too low?

  37. Homeostasis:Effector • Provides the means for the controlcenter's response to the stimulus. • Sends information from the control center (called output) and produces a response called an effect. • Results of theresponsethen feedback to influence the stimulus by either depressing it (negativefeedback)so that the entire mechanism is shut off, or enhancing it(positive feedback) so that the reaction occurs at an even faster rate

  38. Answer: Provide 2-3 specific examples of how humans work to maintain homeostasis. Turn in Ch. 1 reading guide!! Objective: I can use examples to describe how positive and negative feedback mechanisms contribute to homeostasis. Warm-Up: Monday 9/4/18

  39. Homework -Body Systems Project – Due by 3 pm today Agenda Notes: Feedback loops Homeostasis & feedback practice Create multiple choice/short answer q’s for organ system Warm-Up: Friday 9/4/18

  40. An example of a negative feedback loop… • Blood pressure homeostasis • If a stimulus (such as stress) causes blood pressure (controlled condition) to rise, pressure sensitive nerve cells (receptors) in certain arteries send impulses (input) to the brain (controlcenter). • The brain sends impulses (output) to the heart (effector) which causes the heart rate to decrease (response) and the return of normal blood pressure and thus, restoration ofhomeostasis.

  41. r Tend toincrease the stimulus and push the levels that a variable must be maintained at farther, so positive feedback systems are much more rare. r Usually occur infrequently and do not require continuous adjustments c Ex:Birth Example of a positive feedback loop... -

  42. Create assessment items for your organ system!! • 2 MC items • 1 short answer item • YOUR PEERS SHOULD BE ABLE TO ANSWER THE QUESTIONS YOU COME UP WITH BY LOOKING AT EITHER YOUR POSTER OR FACT SHEET!

  43. Back to the Case Study.. When Kati arrived at the hospital and doctors began to collect information, they discovered that she weighed128lbs.Oddly, when she checked in to the race, she weighed 126lbs. The doctor suggests that Kati might have "hyponatremia." What do you think that word means?

  44. Hypo=low Atremia = seroussodium Cause: Sweating out more water thanintaking Extreme hyponatremia can ultimately cause coma anddeath. How does Kati's story relate to HOMEOSTASIS? Which of the 1O life processeswere compromised in Kati'ssituation?

  45. Answer: When we begin to get dehydrated, we usually get thirsty, which causes us to drink fluids. Is thirst part of a negative or a positive feedback control system? Defend your choice. Objective: I can design an experiment that will determine how exercise disrupts homeostasis and how your body attempts to restore it. Warm-Up: Wednesday 9/5/18
