Startup: Week 4In the front of your N.B.
Review before the quiz…10 risk factors for heart diseaseBP lab last weekWhat is the function of the
respiratory system and the structures involved?
Classroom Business! This is week 4. No late work for all previous
assignments accepted after week 4. Be here tomorrow and Wednesday to
analyze data! 5 week grades due next week:
Part 1: Typed lab report for Heart Rate and Blood Pressure lab! Worth 50 points.
Part 2: 1st Notebook check! All warm-ups, handouts, and stamps for assignments are worth 1 point ~ 30-60 HP possible!
Today’s AgendaWeekly Quiz (Risk factors for Heart
Disease, BP Lab, and Respiration)Pass back last week quiz (37-1
Blood Flow)Make sure everyone has complete
data for their lab report.
Startup: How do I write a lab report?Complete in the front of you NB
Step 1: Pick up the “Blood Pressure LAB GRADE Sheet” as you enter.
Step 2: Copy the questions and answer
What three sections are worth the most points? What section has the most parts to it? How many sections are there total to the lab report?

Respiratory System
What does it do?
1. RS brings oxygen into the body
2. Oxygenated blood gets pumped by the CS to cells of the body
3. O2 is exchanged for CO2 at the cellular level
4. Deoxygenated blood is transported back to the lungs via the CS
5. CO2 is expelled by the lungs
YEAH! I’M ALIVE!
Your Breathing
1. Have a partner count the number of breaths you take in 15 seconds. Multiply that number by 4 for the number of breaths per minute.
2. Now, take a deep breath and hold it for as long as you can. Have your partner record your time.
Your Breathing
1. Why are there differences in breathing rates among members of the class?
2. What factors might affect how long you could hold your breath?
3. A child having a tantrum declares she is going to hold her breath “until I turn blue!” Do you think this is possible?
Function• Brings oxygen
into the blood and tissues and carbon dioxide out to the air.
Nasal Passageway
• First structure of the respiratory system.• Mucus moistens the air and traps dust.• Cilia sweep dust so that it is swallowed or
spit out.
Structures
• Pharynx– Passageway for air
and food
• Larynx– Vocal cords
• Trachea– Passageway for air
only
Structures
• Bronchi– Passageway
from trachea to lung
• Alveoli– Air sacs in lungs
that are used for gas exchange
Alveoli
Bronchiole
Capillary
There are 150 millionalveoli in each healthylung!
Gas Exchange
• There are 150 million alveoli in each healthy lung.
• Oxygen diffuses from alveoli into blood cells
• Carbon Dioxide diffuses out of blood cells and into avleoli
Lung Capacity
• What do you think Lung Capacity is?
• What factors do you think affect Lung Capacity?
Lung Capacity
• Tidal Lung Capacity– The amount of air moved in and out of your
lungs in one normal breath
• Vital Lung Capacity– The amount of air exhaled after one DEEP
breath• Experimental Value
– Actually measure how much air you exhale
• Calculated Value– Calculate how much air you should be able to exhale
based on body surface area and age
Breathing• The diaphragm is a muscle at the bottom of
the chest cavity that controls breathing.• The diaphragm contracts when a person
inhales.• When using force to blow out, other muscles
are used.
Let’s Review• What is the first structure of the
Respiratory System?
• The _________ are air sacs located in the __________ where gas exchange occurs
• The _________ is a passageway for both food and air
• List the following structures in order:– Bronchi, Larynx, Nasal Passage, Trachea,
Alveoli, Pharynx

Respiratory System
IV. Diseases of the RSA. Asthma
1. Allergic reaction2. Smooth muscles contract, narrowing
the airways3. Clogs the airways with mucus
B. Bronchitis1. Excess mucus and inflammation of the
bronchioles2. Caused by long-term exposure to
irritants such as cigarette smoke and air pollutants
Respiratory System
C. Cystic Fibrosis1. Genetic defect that causes excessive
mucus production that clogs the airways; die from drowning
D. Pneumonia1. Inflammation of the lungs caused by
Streptococcus pneumoniaeE. Tuberculosis
1. Bacterial infection (Mycobacterium tuberculosis) of the lungs that causes the formation of hard nodules and crusty dead spots in lungs
Respiratory System
V. Effects of Smoking1. Nicotine constricts bronchioles,
decreasing airflow in lungs = bad2. CO binds to hemoglobin reducing O2
carrying capacity = bad3. Irritants in smoke caused increased mucus
secretion and swelling of mucosal lining = bad
4. Irritants in smoke inhibit movement and eventually destroy cilia in lining of RS = bad
5. Over time, the elastic fibers of the lungs are destroyed causing collapse of small bronchioles and the trapping of air in alveoli = bad

Respiratory System
VI. Smoking-Related DiseasesA. Emphysema: Destruction of the
walls of the alveoli resulting in less surface for gas exchange
Respiratory System
B. Chronic bronchitis: Excessive secretion of bronchial mucus
Respiratory System
C. Lung Cancer: leading cause of cancer deaths in US; most people die within a year of initial diagnosis; 85% of cases are related to smoking
