Which of the following is the most complex level of organization in a multicellular structure?
organ systems
cells
organs
tissues
The body's internal environment must stay
within narrow ranges that support human life.
the same as its external environment.
exactly the same at all times.
away from sudden outside temperature changes.
A negative feedback loop causes the body to
shut down a control center.
counteract a change.
change set points.
increase the rate of change.
The process of maintaining a steady body temperature is part of
feedback.
differentiation.
determination.
homeostasis.
Which of the following systems protects the body against disease with white blood cells?
Excretory
Respiratory
Immune
Integumentary
Unlike the parts of the nervous system, the endocrine system's parts
work independently of one another.
are physically disconnected.
control many processes.
communicate with each other.
Growth, development, digestion, and sexual maturity are controlled by the
nervous system.
endocrine system.
muscular system.
circulatory system.
Something that causes your nervous system or endocrine system to produce a response is called a
receptor.

Which phrase best describes a neurotransmitter?
A neurotransmitter acts within a neuron.
A neurotransmitter cannot break down.
A neurotransmitter is a chemical signal.
A neurotransmitter uses a sodium-potassium pump
Which of the following best describes how neurons communicate with one another?
Electrical impulses trigger the release of neurotransmitters into the synapse. These neurotransmitters then bind with matching receptors on neighboring neurons.
Chemical signals move through the axon and release hormones into the blood. These hormones will bind with matching receptors.
Neurotransmitters travel through dendrites until they reach the axon. This creates an electrical signal that is transmitted to the neighboring neurons.
Electrical signals move from the axon to the dendrites causing chemical signals to be released into the cell body. These chemical signals will create a new electrical signal on the neighboring neuron.
The endocrine system uses chemical signals called
target cells.
hormones.
glands.
neurons.
The blood in veins is
leaving the lungs.
moving in single file.
carrying oxygen.
traveling to the heart.
Blood is carried to the cells of the body by the
arteries.
alveoli.
capillaries.
veins.
Why does CO2 diffuse from the blood into the alveoli?
CO2 concentration is higher in the blood than in the alveoli.
The brain signals the alveoli to absorb CO2.
When O2 leaves the blood, another gas must replace it.
There is not enough hemoglobin to carry the CO2.
Which of the following is the correct pathway for air entering a human body?
nose, lungs, trachea, alveoli, bronchi
mouth, trachea, bronchi, bronchioles, alveoli
alveoli, bronchioles, bronchi, trachea, mouth
trachea, alveoli, bronchioles, bronchi, mouth
Which structures of the heart prevent blood from moving backward in the wrong direction?
Valves
Atria
Ventricles
Capillaries
Which of the following best describes our need to breathe?
When we breathe we take in carbon dioxide. Our cells create energy using this carbon dioxide.
When we breathe we take in air that contains oxygen. Our cells use oxygen to create energy.
When we breathe we take in oxygen. Our heart uses this oxygen to pump blood.
When we breathe we exhale carbon dioxide. Trees need this carbon dioxide for photosynthesis.

What is the term that describes the location where two bones meet?
Cartilage
Ligament
Tendon
Joint
What term describes the tissue that cushions bones and allows for smooth movement?
Cartilage
Ligament
Tendon
Joint
Which of the following statements about the muscular system is true?
The muscular system moves bones at joints.
The muscular system pushes blood, food, and fluids throughout the body.
The muscular system helps the body to maintain homeostasis.
All of the above are true.
What type of muscle tissue allows for movement of your bones?
Skeletal muscle
Smooth muscle
Cardiac muscle
Cranial muscle
What type of muscle tissue is found within the heart?
Skeletal muscle
Smooth muscle
Cardiac muscle
Cranial muscle
