Animal Systems

Two body systems work together to help remove waste products from the blood. What are these two systems?

• circulatory/excretory

• skeletal/digestive

• circulatory/integumentary

• muscular/excretory

The main function of the excretory system is to -

• produce enzymes to help digest food

• collect and remove waste products from the body

• prevent disease and fight infections

• carry oxygen and nutrients to the body's cells

Which two body systems help the body to break down molecules and absorb nutrients and exchange oxygen and carbon dioxide?

• respiratory/reproductive

• muscular/skeletal

• digestive/respiratory

• circulatory/endocrine

The largest human body organ, which regulates temperature and serves as a barrier against harmful microorganisms, belongs to the -

• circulatory system

• nervous system

• digestive system

• integumentary system

The human body has specialized organs called glands which collect and

process substances from the blood. The concentrated substances are

then secreted as hormones to regulate body processes.

These specialized organs are part of which body system?

• circulatory

• endocrine

• integumentary

• nervous

Ovaries produce and secrete hormones in addition to eggs. To what

human body systems do ovaries belong?

• integumentary/reproductive

• excretory/muscular

• endocrine/reproductive

• nervous/digestive

The main function of the muscular system is ―

• support of the body

• breakdown of food

• movement of the body

• removal of waste

Which organ system is responsible for transporting oxygen throughout

the organism?

• Endocrine

• Respiratory

• Excretory

• Circulatory

Which statement best describes the function of the human body system

in the above diagram?

• Breaks down food into nutrients and wastes

• Supplies oxygen to blood and removes carbon dioxide from blood

• Provides support and movement for the body

• Produces and secretes hormones which regulate metabolism, growth,

  and development

Which four body systems interact to allow a person to sneeze?

• Muscular, immune, nervous, respiratory

• Nervous, respiratory, circulatory, skeletal

• Respiratory, endocrine, skeletal, circulatory

• Lymphatic, skeletal, respiratory, muscular
