Slide 1

Homework: Paragraph in NB on respiratory disorderSilent Do Now: (in NB w/ title and date)Take out your lab report and put it on your desk.List some of the organs in the respiratory system.What is the function of the respiratory system?Flip back to your notes from 10/14/11 and find the equation for cell respiration. What is the purpose of cell respiration?How does the respiratory system relate to cell respiration?Todays Objectives:Describe the structures and functions of respiratory system organs, and explain how they relate to each otherBio 9B: Monday, 12/19/11Title: Respiratory System1Respiratory System12/19/11Respiratory System: Structures and Functions Day 1 (1st Half of Double Block)Complications of the Respiratory SystemAgenda

Cellular Respiration: Summary EquationGlucose+H2O+CO2O2+heat+ATP energyWe exhale this when we breathe outWe inhale this when we breathe in This is the energy that our cells use to do workObjectives for Class:Connect cell respiration to systems of the human bodyWrite the summary equation for cell respirationPurpose of the Respiratory System

Objectives for Class:Describe the difference between structure and function, and explain how an objects structure relates to its functionDescribe the major structures and functions of all organs in the respiratory systemTransport O2 from the air into the bloodstreamRelease CO2 from the bloodstream into the airAll because of CELL RESPIRATION:Cells need O2 for cell respiration to make ATPCells release CO2 as a waste product from cell resp.

Structures of the Respiratory SystemObjectives for Class:Describe the difference between structure and function, and explain how an objects structure relates to its functionDescribe the major structures and functions of all organs in the respiratory system

Structures of the Respiratory System:Mouth & Nose: Take in airMoisten/filter the air (nose hairs, saliva & mucus)Trachea (aka windpipe): The main airway tothe lungs.Made of stiff cartilage

Objectives for Class:Describe the difference between structure and function, and explain how an objects structure relates to its functionDescribe the major structures and functions of all organs in the respiratory systemLungs: Main organs of the respiratory system where gas exchange happens. Bronchi: Tubes that branch off from trachea. One major bronchus for each lung branches into smaller and smaller bronchioles in the lungStructures of the Respiratory System:

Major Bronchi BranchingObjectives for Class:Describe the difference between structure and function, and explain how an objects structure relates to its functionDescribe the major structures and functions of all organs in the respiratory system

Smaller Bronchioles Branching in the lung9Alveoli: Tiny air sacs at the ends of the bronchioles where gas exchange takes place. Look like GRAPES!Surrounded by a network of capillaries tiny blood vessels that trade O2 and CO2 with alveoli

Complications of the Respiratory SystemWork quietly and productively with members of your own group.First, work together to complete the Respiratory System WorksheetWhen finished, raise your hands to get your work checked, and to get a Respiratory System Complications packet and instructionsAssign jobs and continue working quietly and productively to complete page 1 of the packetYou should not be: wandering or talking with other groupsHW: One paragraph on your disorder, in your notebook.

Homework: Study for Thursdays Quiz by answering questions #1-6 on the back of the study guideSilent Do Now: (in NB w/ title and date)What is the structure of the bronchi? See pictures above and below for a reminder (Are bronchi tubes? Sacs? Solid lumps?)What is the function of the bronchi? (check yesterdays notes)What would happen to the function of a bronchus if the diameter got smaller?Todays Objective:Describe the structures and functions ofrespiratory system organsBio 9B: Tuesday, 12/20/11Title: Respiratory System Complications

16Todays AgendaReview the Do NowFinish the Jigsaw Activity 15 more minutes in groupsReflection 15 minutes of silent individual writing

Goal for today: You should be able to:Explain how the structure of each respiratory organ helps with its functionApply this knowledge to explaining the causes and symptoms of respiratory disorders

Complications of the Respiratory System:Group JigsawSit at your table from your second group from yesterday.Group members report out on their issue (15 more minutes)5 minutes per person to share informationEveryone else records information in your packetIf your group finishes early:3-person groups get another info sheet and learn about another complication4-person groups start the Reflection on the back of the packet

Complications of the Respiratory System:Individual ReflectionReturn to your regular seatTake the next 15 minutes to silently complete the Reflection on the back of the packet.

I will be handing back some work and checking in with individual students. Please work silently so that you do not disrupt this process!

If you finish early:Get an extra credit reading assignment (on kidney table)Begin reviewing for Thursdays Quiz start HW

Plan for Thursday:Notes on Breathing and Gas Exchange (25 minutes)Quiz Review (25 minutes)Quiz (up to 50 minutes)

Tonights HW: Complete Questions #1-6 on the Study Guide (back of assignment sheet)Homework:Have a great vacation & a happy new year!Silent Do Now: (in NB w/ title & date)Write todays title & date in your notebookBreathe in a deep breathe. Then breathe out. Do this several times while paying attention to what is happening to your body.Write down at least 3 observations in your notebook.Todays Objectives:Explain how the diaphragm control the process of breathing.Explain how diffusion and concentrations create gas exchange in the lungs.Demonstrate knowledge on the quiz!Bio 9B: Thursday, 12/22/11Title: Breathing & Gas Exchange21Period 3: Do Now Notes: Breathing Breath-Holding Exercise & Debrief Notes: Gas Exchange Quiz ReviewPeriod 4: Quiz on Membranes & Respiratory System

Todays Agenda & AnnouncementsTodays Objectives:Explain how the diaphragm control the process of breathing.Explain how diffusion and concentrations create gas exchange in the lungs.Two Important Processes in the Respiratory System:(Dont need to write this down just a preview)Breathing controlled by the diaphragmGas exchange happens in thealveoli

Todays Objectives:Explain how the diaphragm control the process of breathing.Explain how diffusion and concentrations create gas exchange in the lungs.

Diaphragm:

A large flat muscle that controls breathing

Located at the bottom of the chest cavity

BREATHING:Todays Objectives:Explain how the diaphragm control the process of breathing.The Process of BreathingInhaling:Diaphragm contracts & lowersVolume of lungs increases (partial vacuum)Air rushes in (through mouth/nose, trachea, bronchi, to alveoli) to fill the spaceExhaling:Diaphragm relaxes & bends upwardVolume of lungs decreasesAir is forced out (from alveoli through bronchi, trachea, mouth/nose)

Todays Objectives:Explain how the diaphragm control the process of breathing.25

Quick Activity Holding Your BreathObjectives for Class:Describe the difference between structure and function, and explain how an objects structure relates to its functionDescribe the major structures and functions of all organs in the respiratory systemHold your breath for as long as you can (on my start)While you are holding your breathe, observe what happens to your body the longer you try not to breathe.Record these observations in your notebook.

Debrief: Talk to your partner for 1 minute about how you did and how it felt:What did you observe about your body as you tried to hold your breath?

The Process of Gas Exchange

Alveoli(air sacs at ends of branches in lungs)Capillary(tiny blood vessel)Blood w/ little O2 and lots of CO2O2CO2O2 diffuses into blood in capillaryCO2 diffuses into alveoliBlood w/ lots of O2 and little CO2The Process of Gas Exchange

Oxygen diffuses from alveoli into capillaries (tiny blood vessels) and binds to red blood cellsCarbon dioxide diffuses from capillaries into alveoli Objectives for Class:Describe the difference between structure and function, and explain how an objects structure relates to its functionDescribe the major structures and functions of all organs in the respiratory systemGas exchange the diffusion of oxygen and carbon dioxide across cell membranesHappens in the alveoli of the lungsThe Process of Gas ExchangeGas exchange in the lungs needs MAD surface area for enough O2 and CO2 to diffuse!Lungs contain 1.3 million alveoli!!The total surface of all the alveoli would cover half a tennis court!!
