Pre-assessment
____ 1
The body is made up of many systems that interact with one another. For
example, the skeletal system and the muscular system work together to help the body
move. Which system works with the respiratory system to distribute oxygen to the body?
A muscular system
B digestive system
____ 2
C lymphatic system
D circulatory system
Billy drew a picture of a human body system on the board.
He told the class which organ removed most of the water from food. To which body
system was he MOST likely describing?
A
B
C
D
Digestive
Excretory
Nervous
Urinary
_____ 3.
Eleonora is learning about the nervous system in school. She learns the
nervous system is made up of many parts.
What is the main purpose of the nervous system in the human body?
A.
B.
C.
D.
relaying messages between the body and brain
circulating oxygen throughout the body
releasing hormones to regulate body functions
protecting the body from foreign invaders

Post-Assessment
____ 1
The human body is organized into systems that carry out all functions by working
together. Which activity in the body MOST closely describes a relationship between the circulatory
system and the digestive system?
A
B
C
D
Nutrients are absorbed into the bloodstream.
The body grows antibodies in response to a virus.
The kidneys remove harmful wastes from the blood.
Red blood cells exchange carbon dioxide for oxygen.
_____ 2. Homeostasis describes the stable environment that the human body maintains, enabling the
body to function properly. When an outside stimulus threatens to disrupt homeostasis, body systems
work to bring things back into balance. Which of the following directly describes systems working
together to maintain homeostasis?
a. The circulatory system moves waste products from the stomach to the excretory system.
b. The nervous system senses cold temperatures and causes muscles to contract and relax rapidly.
c. The respiratory system releases hormones to regulate the immune system and fight germs in the
body.
d. The digestive system releases heat as it digests food, which the circulatory system spreads
throughout the body.
_____3. Body systems such as the nervous and digestive systems work together and help the body
maintain homeostasis. Which of the following correctly describes one way that the nervous system
and the digestive system work together?
a. Lungs contract during chewing so that food won’t be inhaled.
b. Blood flow to the stomach and intestines decreases during eating.
c. The involuntary muscles in the jaw stimulate spinal cord neurons to initiate chewing.
d. Neurons in the brain stimulate smooth muscles in the intestines to move food through the body.
_____ 4. Sandra measured her heart rate and her breathing rate at rest and again after doing 50
jumping jacks.
Heart Rate
Breathing Rate
Resting
70
12
After Exercise
125
25
What is the main reason that both her heart rate and her breathing rate went up with exercise?
A. They both sped up to supply her working muscles with enough oxygen to remain in
homeostasis.
B. Her lungs and heart ran short on oxygen while she was exercising and sped up to maintain
homeostasis.
C. Her muscles were out of shape and required extra blood and oxygen in order to maintain her
jumping pace.
D. They both increased in order to carry heat away from her working muscles more efficiently.
