5. Read p. 63-69
6. Complete WB 24a
7. Discuss the structure of the heart: The heart is the size of a fist. It’s made of a very strong
muscle. The heart is divided into four chambers: right auricle, right ventricle, left auricle, left
ventricle. A series of valves open to allow blood flow from one chamber to the next. A muscle
wall called the septum separates the left and right side of the heart.
8. Complete The Heart WS for INB
9. Color body page 113 in The Body Book according to the oxygenation of blood as it pumps
throughout the body. Add this to the INB.
10. Listen to heart with a stethoscope
11. Locate pulse on wrist. Count the pulse for 15 seconds and multiple this by 4 to get beats per
minutes (multiply beats per minute by 60 to get beats per hour, multiply this result by 24 to get
beats in one day). Then run in place for 2 minutes. Check pulse again. Have students explain why
pulse when up.
12. Create a model of the blood -add ingredients to a ziplock bag: Plasma = corn syrup, White blood
cells = marshmallows , Platelets = rice, Red Blood Cells = red hots1.
a. Plasma The liquid part of the blood. About 90% of the plasma is water. The other
10% of plasma is made up of such items as proteins, fats, carbohydrates, and
mineral salts. These parts of plasma are responsible for growth (body tissues)
and energy.
b. Red Blood Cells The solid part of the blood. The red blood cells are the most
numerous of the three types of cells. The function of the red blood cells is to
carry oxygen from the lungs to different body tissues and to transport the carbon
dioxide away from the tissues. Red cells contain a chemical called hemoglobin
which absorbs oxygen and gives blood its red color. Blood which returns to the
heart is a darkened red color due to the lack of oxygen.
c. White Blood Cells White cells, also known as leukocytes, also make up the solid
part of the blood. These cells serve a major purpose. They help fight off diseases
by wrapping themselves around any dangerous microbe and engulfing it. White
cells are not white but are of a colorless nature.
d. Antibodies, which are blood proteins also aid in helping to fight off foreign
invaders such as viruses. Antibodies also maintain the body’s immunity to
disease by reacting to foreign substances before a disease can occur.
e. Platelets They are tiny living colorless particles in the solid part of the blood that
help form blood clots. Drops of blood coming out of a cut begin to thicken. They
cling together. Instead of being liquid, the blood turns to a jelly that fills the cut
completely. This jelly hardens, forming a seal which prevents blood from leaking
out and prevents bacteria from creeping in. From the above information,
students can see why blood is so important and so vital for life. The responsibility
of the blood for transporting Op and C02 to all areas of the body is essential
otherwise damage to cells and tissues can occur.

Respiratory System

2. Brainpop http://www.brainpop.com/health/bodysystems/respiratorysystem/
3. Read p. 70-73
4. Complete WB 25a
5. Label parts of the respiratory system
6. Count the number of times you breathe in as your time one minute. Multiply by 60 and the
result by 24 to find out how many times you breathe in one day. Run in place for 2 minutes and
count again. Is there a difference? Why?
7. Put together a model of the respiratory system (The Body Book p. 104-106)
8. Discuss the diseases of the respiratory system (worksheet)
9. Read “How do the respiratory and circulatory system work together?”
