Introduction

This unit of study is meant to increase
your awareness of the human circulatory
system, its major parts, the functions of
these parts, as well as how these parts
work together with those of the previously
studied respiratory system to promote
overall health in the human body.
Your objective is…

In this activity, you are expected to learn the
parts of the human circulatory system along with
their corresponding functions.

Overview:
Major Parts of the Circulatory
System
Heart
– Atria
– Ventricles
– Valves

Blood
–
–
–
–

Plasma
Platelets
Erythrocytes
Leukocytes
Blood Vessels
– Arteries
– Veins
– Capillaries
Directions:
The following is a breakdown of individual and group
work that you will complete during this unit of study.

Individual Work
– KWL chart regarding the
circulatory system.
– Labeled diagram of human
heart.
– Manipulation of human body
model to properly place
circulatory system parts.
– Answer teacher questions
regarding human circulatory
system, and its link to the
respiratory system.

Group Work:
– Worksheet booklet identifying
parts of circulatory and related
systems, along with
corresponding quiz.
– Access interactive websites
that help in learning the parts
of the human circulatory
system.
– Construct a Word report or
PowerPoint presentation
addressing one disorder of the
human circulatory system.
Reports will be presented to
the class.
KWL Process:
The “K” and the “W”

Before beginning instruction, begin your KWL chart
provided by the instructor. Fill in the following:
– K: What do you already know about the human circulatory
system?
– W: What do you want to learn about the human circulatory
system?
Let’s begin…
Take out your circulatory system booklet
handouts.
 With your partner, read through the
information provided in the booklet, and
complete the corresponding activities and
quiz at the end.
 Once you have finished, see me for
feedback on your completed booklet.

Notes:
Blood’s role in the circulatory system:

Blood is made up of:
– Red Blood Cells (Erythrocytes) – carry oxygen to the body’s cells,
and remove carbon dioxide waste from these cells.
– White Blood Cells (Leukocytes) – they help fight infection in the
human body.
– Plasma – this is the lubricant for red blood cells – it is the water
portion of blood that allows erythrocytes to flow steadily.
– Platelets – these are produced when there is a break in a blood
vessel due to an injury. They produce scabs and help clot blood,
preventing major blood loss in the event of minor-medium
severity injuries.
Notes:
The role of blood vessels:

Arteries: These are the largest vessels in the human
body. They carry blood away from the heart and to the
rest of the body.

Veins: These vessels are medium-sized, and carry blood
back to the heart once it has circulated through the
body.

Capillaries: These vessels are the smallest. Their walls
are thin and porous, therefore making it easy for oxygen
and carbon dioxide gases to enter and exit the
bloodstream.
Notes:
The basic role of the human heart:

The human heart is divided into chambers:
– Left and Right Atria: These two smaller chambers are
located at the top of the heart. Blood pumps through
these chambers after returned by the veins.
– Left and Right Ventricles: These two lower chambers
are larger, and squeeze blood from the heart through
arteries and to the rest of the body.
– Valves: These are located between atria and
corresponding ventricles; they are a passageway for
the flow of blood from one chamber to the next.
We will now move into the computer lab, where you will
each work with a partner at your own computer
terminal.

Once you are in the lab, you will access
the following sites:
The heart with labels:
– http://www.edhelper.com/teachers/health_He
art_with_Labels.htm
The Circulatory System Movie:
– http://kidshealth.org/kid/htbw/CSmovie.html.
Once you are in the lab:

1. Access the first site, with the labeled heart. Check your
own heart diagram and make certain your labels are
correct.

2. Access the second site. This site provides audio and
video – which we will view together using the SyncronEyes
technology.

3. Using the video regarding the circulatory system, write
one additional piece of information regarding each system
part into your graphic organizer used during notes.

Should you have any questions, do not hesitate to
ask the teacher for help!!!
Using http://www.google.com :
Search for disorders or diseases of the
circulatory system.
 Complete either a one page typewritten report
(double spacing, size twelve font, one inch
margins all around) or a PowerPoint
presentation (minimum of 5-8 slides)
summarizing the definition, causes, symptoms,
and treatments or cures for this
disorder/disease.
 You and your partner will report back to the
class on your chosen disease.

Now, using your knowledge from
the previous unit:

Individually answer:
– How do the human respiratory and circulatory
systems work together to promote human
health in the body?
Revisiting the KWL:
Filling out the “L”

Upon completion of this activity, you must
revisit your KWL chart, and fill in the “L”
component.
– L: What you have learned about the
circulatory system that you did not know
before studying this unit.
Survey: Evaluation of What Was
Learned

Students, please access the following website and
take the survey located on this page. I would love to
have feedback regarding how well you feel you
learned the information presented in the units
pertaining to the human circulatory and respiratory
systems!

Student Evaluation

You will be evaluated individually by your
teacher on all aspects of this unit using the
rubric established before instruction began.
