30.1 Organization of the Human Body
Lesson Objectives
Describe how the human body is organized.
Explain homeostasis.
BUILD Vocabulary
A. The chart below shows key terms from the lesson with their definitions. Complete the chart by
writing a strategy to help you remember the meaning of each term. One has been done for you.
Term
Definition
How I’m Going to Remember the
Meaning
Connective
tissue
Tissue that supports and connects
body parts
Remember connect is in connective
tissue.
Epithelial tissue
Tissue that lines the body
Feedback
inhibition
A stimulus produces a response
that opposes the first stimulus
Homeostasis
Maintaining a controlled and
stable internal environment
Muscle tissue
Tissue responsible for movement
Nervous tissue
Tissue that receives, processes
and transmits messages
B. As you work through this lesson, you may find these terms in the activities. When you need to
write a key term or a definition, highlight the term or the definition.
BUILD Understanding
Preview Visuals After you preview Human Body Systems, answer the following.
1. How does visualizing the connections between body systems help you understand
homeostasis?
2. Find a partner. Examine the diagram in your textbook. Then discuss some ways the nervous
system works with other body systems.

Organization of the Body
The human body is made up of many different systems, each with a specific purpose.
Label the diagrams below with the correct name of the body system
Homeostasis
Feedback Inhibition Feedback inhibition occurs when high levels of a substance slow or
stop the process that produces the substance. The diagram below shows how feedback inhibition
works in a home heating system.
Number the descriptions below to identify the parts of the feedback inhibition process shown
in the cycle diagram above.
Thermostat senses temperature change and switches on heating system.
Room temperature increases.
Room temperature decreases.
