Title: Challenge Problem


1
Challenge Problem
  1. The function of the urinary system is to___
  2. T/F- the heart and blood vessels belong to the
    muscular system
  3. Give an example of when the nervous system is
    used.
  4. Lungs and the trachea are part of the ____
  5. Why is the integumentary system important?

2
The Human Body
  • An Orientation
  • Part 1

3
Review
  • What is Anatomy?
  • Give an example of Anatomy of the Cardiovascular
    System
  • What is Physiology?
  • Give an example of Physiology of the Digestive
    System

4
  • Get out system notes from Friday
  • If you need to get your poster do so now.

5
Overview
  • Levels of Structural Organization
  • Maintaining Life
  • Homeostasis

6
Levels of Structural Organization
  • What is the smallest thing known to Humankind?
  • What are ALL THINGS (living and non-living) made
    of?

7
From Atoms to Organisms
  • 1) Atoms
  • Tiny building blocks of matter
  • 2) Cells
  • The smallest unit of living things
  • 3) Tissues
  • A group of similar cells that have a common
    function

8
From Atoms to Organisms
  • 4) Organ
  • Made of two or more tissues and performs a
    specific function for the body
  • 5) Organ System
  • A group of organs that cooperate to accomplish a
    common purpose
  • 6) Organism
  • A group of organ systems that make up the highest
    level of living structural organization

9
The Human Organism
  • Without looking at your notes,
  • Can you name all 11 organ systems that make up
    the human organism?

10
Body Systems
  • Skeletal System
  • Muscular System
  • Nervous System
  • Endocrine System
  • Cardiovascular System
  • Lymphatic System
  • Respiratory System
  • Digestive System
  • Urinary System
  • Reproductive System
  • Integumentary system

11
Maintaining Life- stuff we have to do
  • 1) Maintaining Boundaries
  • Organisms must keep their insides separate from
    the outside
  • Which Human Body System maintains this essential
    boundary?
  • Why is maintaining a boundary important?

12
Maintaining Life
  • 2) Movement
  • Necessary for motility and to perform bodily
    functions such as digestion and pumping blood.
  • Which Human Body System is responsible for
    movement?
  • Why is motility important?

13
Maintaining Life
  • 3) Responsiveness
  • The ability to sense changes in the environment
    and react to them
  • What TWO Human Body Systems are responsible for
    responsiveness?
  • Why is responsiveness important?

14
Maintaining Life
  • 4) Digestion
  • The process of breaking down food into molecules
    that can be used by the body
  • 5) Metabolism
  • All chemical reactions that occur in the body
  • 6) Excretion
  • The process of removing wastes from the body

15
Maintaining Life
  • Why is it important to be able to break down food
    through digestion?
  • Why do you think chemical reactions are necessary
    in the body?
  • Why is it important to be able to excrete waste
    from the body?

16
Maintaining Life
  • 7) Reproduction
  • The production of offspring
  • Why is reproduction an important function of the
    body?

17
Maintaining Life
  • 8) Growth
  • An increase in size
  • Why is growth an important aspect of living
    things?

18
Maintaining Life- stuff we need
  • Survival Needs
  • Nutrients
  • Oxygen
  • Water
  • Body Temperature
  • Atmospheric Pressure

19
Challenge Problem- 9/4/14
  • 1. Older people with diabetes will often end up
    with kidney failure. What would result if a
    person loses function of their kidneys?
  • 2. Compare the urinary system and the digestive
    system. (how are they similar?)
  • 3. Contrast the integumentary system and the
    skeletal system. (how are they different?)

20
FLT
  • I will be able to tell my partner what
    Homeostasis is and give and example of how it is
    controlled by taking notes and a quiz before I
    get out of class

21
Homeostasis
  • What do you think Homeostasis means?

22
Homeostasis
  • Homeostasis
  • The bodys ability to maintain relatively stable
    internal conditions despite ever-changing
    external conditions
  • In your notes, write a definition with an example
    in your own words.

23
Brainpop
  • Take 2 minutes and see if you can answer the
    questions before we we watch the video

24
Homeostasis
  • How do we control Homeostasis?
  • Negative Feedback Loops (Feedback Inhibition)
  • A system in which the effect of a stimulus turns
    off or reduces the original stimulus
  • Lets look at an example

25
Feedback Inhibition LoopA home heater
Thermostat senses temp. increase and switches
heater off
Room Temp. Increases
Room Temp. Decreases
Thermostat senses temperature decrease and
switches heater on
26
How is the house heater like the Human Body?
  • What happens to you when you get very cold?

27
Feedback Inhibition LoopYour Body - too COLD
Your body stops shivering (Thermostat OFF)
BODY Temp. Increases to normal
BODY Temp. Decreases too much
Your body shivers and shakes to warm you
(thermostat ON)
28
  • What about when you get too hot? What happens?

29
Feedback Inhibition LoopYour Body - too HOT
Your body produces sweat to cool you.
BODY Temp. Increases too much
BODY Temp. Decreases to normal
Your body stops producing sweat
30
Feedback Inhibition
  • Feedback inhibition is a process utilized by many
    body systems in order to maintain homeostasis.

31
Homeostasis
  • Write in your notes an example that will help you
    remember what Negative Feedback is.
  • What happens when our bodies are unable to
    maintain homeostasis? (Homeostatic Imbalance)

32
Quick Quiz 5 min
  • 1. Name the 6 levels of living structural
    organization.
  • 2. Name one of the requirements for maintaining
    life(functions), and say why it is important.
  • 3. Give a definition for Homeostasis IN YOUR OWN
    WORDS
  • 4. Give an example of a Negative Feedback Loop
  • Why are they needed/why are they important
