4/29 Objective
Discuss the structures and functions of the
circulatory and respiratory system and how
they work together to maintain
homeostasis.
Essential Questions
 1. What are the functions of the circulatory and
respiratory system?
 2. What are the major organs we need to know?
 3. How do we keep our lungs and heart healthy?

Heart Rate Lab




Directions: Pair up with a partner.
Open up your body packet to the Heart rate lab
Read the directions
Create a hypothesis as a pair and identify the IV and DV
 Time: 8 minutes
 Noise: 1 (with partner)
Lab
 Directions: Complete the chair sit lab. You will measure heart
rates before and after physical activity to demonstrate how the
cardiovascular and respiratory systems work together.
 Time: 6 minutes
 Noise: 1 (with partner)
The function of the circulatory system
Key Point #1: Function
 Transport nutrients, gases, and wastes
throughout the body.
Who is the transporter of the
body?
The Transporter
Blood delivers materials in the body
Vena Cava
Aorta
Veins
Arteries
Arterioles
Capillaries
Venules
The anatomy of the circulatory system
Key Point #2: Main organs
Heart
Blood
Blood Vessels
The Heart
 1. Heart:
 Muscular organ
 Pumps blood through 4 chambers
 Size of your fist
 Beats about 72 times per minute at rest and about 100,000 times
per day
The Blood
 2. The Blood:
 Made of plasma, platelets, red blood cells and white
blood cells
 Carries nutrients and gases
 The heart pumps 2,000 gallons of blood per day
The Blood Vessels
 3. Blood Vessels:
 Tubes that transport blood
 Arteries:
 Veins:
 Capillaries:
 The blood travels 60,000 miles through blood
vessels a day
The Blood Vessels Continued
Arteries: Carry oxygenated blood AWAY from
the heart to the body
 Veins: Carry deoxygenated blood INto heart and
lungs to receive oxygen
 Capillaries: Exchange oxygenated blood for
deoxygenated blood
 * this is where the veins and arteries connect*
Organ spotlight
The Heart
 Blood enters the heart in the
right atrium and travels to
the right ventricle
 Blood pumps to the lungs to
get oxygen
 Oxygenated blood enters to
left atrium and the left
atrium where it is pumped
out of the heart to the body

Pg. 65 Respiratory System
Heart rate
Key point #1: Heart Rate
 Heart beats per minute
 bpm
Heart rate measures how fast blood is
moving through your body.
What is a normal resting heart rate?
Average adult
 In shape
 Good athlete
 Excellent athlete

70-100 bpm
60-70 bpm
50-60 bpm
<50 bpm
Michael Phelps’ resting heart rate is in
the 30s!!
During a slow warm-up swim…
Michael’s heart rate is
about 50 beats per
minute
What about when Michael races?
Michael’s heart rate after a race
increases to about 200
beats/min
So….
Why does heart rate
increase after activity?
BACK TO NOTES!
The function of the Respiratory
System:
 Key Point #2: Function
 To exchange the Oxygen (O2) for Carbon
Dioxide (CO2)
 Breath in O2
 Breath out CO2
Back to the cell…
When someone does
physical activity,
their cells need
ENERGY! They must
go through cellular
respiration.
Key Point #3: Cellular
respiration is the
process that
produces energy
(ATP)
Blood delivers
oxygen to cells for
respiration
Blood takes away
the CO2 waste from
respiration
Back to the cell…
Key Point #4:
More activity
means the cell
needs more
OXYGEN!
Blood delivers
oxygen to cells for
respiration
Blood takes away
the CO2 waste from
respiration
The Respiratory System
 Cells
release CO2 in the blood
during respiration. There is no
CO2 in the lungs so it diffuses out
of the blood and you breathe it
out.
 The O2 you breathe in diffuses into
the blood because there is a lot of
CO2 in the blood and not a lot of
oxygen.
Key
Point #5:O2 and CO2 diffuse
in and out of the body
Review: Diffusion
Diffusion means to GO from ? to ?
It requires no ENERGY! (Passive transport)
The anatomy of the respiratory system
Flow of molecules
Key Point #6:
 Nose & mouth larynx trachea
bronchi alveoli
 Key Point #7: the alveoli are the function unit of the respiratory
system
 ‘Grapes”

ORGAN SPOTLIGHT!
Nose
 1. Nose & Mouth
 Takes in and filters air
ORGAN SPOTLIGHT!
2. Trachea
 Tube that carries
oxygen from the nose
to the lungs
ORGAN SPOTLIGHT!
Bronchi
3. Bronchi
Branch into
lungs from
trachea

Alveoli
4. Alveoli
Alveoli
tiny air sacs
“grapes”
Site of oxygen
and CO2
exchange
Tell me what ya know!
C= circulatory R=respiratory
Carries nutrients to your body
CIRCULATORY
C= circulatory R=respiratory
Breathes out CO2
RESPIRATORY
C= circulatory R=respiratory
 This is the site of O2 and CO2 exchange in the
respiratory system
 The alveoli
 This is the site of O2 and CO2 exchange in the
cardiovascular system
 Capillaries
Review
 Oxygen and carbon dioxide are exchanged in the
ALVEOLI through the respiratory system
 The circulatory system transports nutrients, gasses,
and wastes to where they need to go in the body
 The circulatory and respiratory system work together
to maintain homeostasis in your body by keeping the
right balance of gases in your body
Work Time
 Directions: Quietly work on part 2: match the proper organ
to the function of the circulatory assignment. The
circulatory worksheet is homework and due Monday.
