Systems, Support, and Movement
the BIG idea
The human body is made up of systems that work together to perform
necessary functions.
1.1 The human body is complex.
1.2 The skeletal system provides support and protection.
1.3 The muscular system makes movement possible.

KEY CONCEPT
CHAPTER HOME
The human body is complex.
How many bones are in your hand?
Use a pencil to trace an outline of your hand on a piece of
paper. Feel the bones in your fingers and the palm of your
hand. At points where you can bend your fingers and
hand, draw a circle. Each circle represents a joint where
two bones meet. Draw lines to represent the bones in your
hand.
VOCABULARY
tissue
organ
organ system
homeostasis
How many bones did you find? How many joints?
There are 19 bones in a hand and 14 joints. A joint allows
movement between two bones.

CHAPTER HOME
KEY CONCEPT
The human body is complex.
You can think of the body as having five levels of
organization: cells, tissues, organs, organ systems, and
the whole organism itself. The different systems of the
human body work together to maintain homeostasis.

KEY CONCEPT
The skeletal system provides support and
protection.
Draw a sequence diagram showing the levels of
organization of the human body, from simplest to most
complex.

CHAPTER HOME
KEY CONCEPT
The skeletal system provides support and
protection.
Bones are living tissue. The skeleton
is the body's framework and has two
main divisions, the axial skeleton
and the appendicular skeleton.
Bones come together at joints.
