Structure of the Heart
Work through the following activities either individually, with your partner, or as a group as
indicated. You may have difficulty with some parts but try and work through them using other
class members and your text/notes. Make sure you finish the packet by the end of class
Wednesday 1/15/14
On my web page you will find the National Geographic – Heart Structure and two embedded
videos that will help you with the activities below. Make sure you read the information below
the National Geographic animations.
When asked to do individual work, try and complete as much as possible before checking with
a partner. This will benefit you in the future as you will be responsible for understanding all
this work
You will receive a grade on the completeness of your work and other grades for the quality
and correctness of your work.
A. Partner: Label diagram A with a partner. Use the heart models to identify the structures
shown on the diagram. Use the National Geographic website for information that will enable
you to explain to the teacher how blood flows through the heart. (Grade)
B. Individual: Try and label diagram B. You may find this a little more difficult but use
diagram A to help you if you have problems. Check your labels with at least two other people
before proceeding
C. Individual: Next to each chamber/blood vessel on diagram B label write either O2 or CO2
to indicate the major gas contained in that blood. Again check your work with at least two
other people
D. Partner: Write the following key on your diagram BLUE – deoxygenated blood, RED –
oxygenated blood. Use the key to color the heart vessels/chambers.
E. Group: Diagram C shows a simplified version of the circulatory system. Examine the
diagram and write the labels corresponding to numbers 1-12 on the top of the sheet. Write the
following key on your diagram BLUE – deoxygenated blood, RED – oxygenated blood. Color the
diagram.
F. Group: View the Blood Circulation video and bellow Diagram C write a few sentences to
differentiate between what is happening at #4 and #10 labels (possible vocab. - gas exchange,
oxygen, carbon dioxide)
G. Individual or Group: Examine the National Geographic clips on the beating heart and
heart valves. On the back of diagram C note down how the heart makes the lub/dub sound.
Watch the Blood Circulation 2 video and note the meaning of diastole and systole.
H.
Individual: Answer the following questions in full sentence form below
1.
Why does the heart exists as two pumps? Why not one? (3)
2.
Why is it so important to separate oxygenated and deoxygenated blood? (3)
3. Choose any structure of the heart and describe the effects on the body of either damage
to, or a malfunction in, this part. (4)
I.
Partner: Complete the heart anatomy circulation worksheet. This will review all the
concepts about the heart and circulation you have learned up to this point.
