The document discusses the key organ systems and tissues that make up the human body as an organism. It describes the circulatory system which is made up of the heart, blood vessels, and blood. The heart pumps blood through the vessels to circulate it through the body. It also describes the excretory system made up of kidneys, which eliminate waste and maintain balance. The kidneys are composed of smaller parts that filter waste and reabsorb water and nutrients. Finally, it notes that organs are composed of tissues like muscle and cells, and damage to these could impair organ systems and harm the organism. [/SUMMARY]

5. Have you ever asked
yourself what makes

organisms around you?
Look at the model of a
human torso?

7. Q1. What do you see?
Describe the model of
a human torso.

8. Below are some organ systems
that you may be familiar with.

9. Q2. Can you identify
these organ systems?
Q3. How do these
organ systems work
together?

10. A model of a Human Heart

11. The circulatory system is one of the
organ systems that make up an
organism. It is made up of the
heart, blood vessels, and blood.
Your heart is about the size of your
fist. It pumps and circulates blood
to the different parts of the body
through the blood vessels.

12. Q4. What are the parts that
make up a human heart?
Q5. What will happen to the
heart if any of these parts is/are
injured?
Q6. What will happen to the
organism?

13. Model of a Human Kidney

14. The excretory system is
another organ system that
makes up an organism. It is
made up of different organs
that help the body eliminate
metabolic wastes and
maintain internal balance.

15. These organs
include a pair of
kidneys. What
shape do they look
like?

16. The kidneys are made up of
even smaller parts. Some
parts eliminate wastes that
are no longer needed by the
body; other parts function in
the reabsorption of water
and nutrients.

17. Q7. What parts make up
the kidneys?
Q8. What will happen to
the kidneys if any of these
parts is/are injured?
Q9. What will happen to
the organism?

18. Muscle Tissue

19. Organs are made up of tissues.
The heart, kidneys, and the
parts that make them up are
made up of tissues. Tissue is
made up of cells - the basic
units of structure and function
in organisms.

20. Q10. What will happen to the
organs if these tissues are
injured?
Q11. What will happen to the
organ systems?
Q12. What will happen to the
organism?
