• Pump blood throughout body and carry nutrients, oxygen, and waste

• nervous system

• add oxygen to and remove carbon dioxide from blood

• skeletal system

• support the muscles and organs

• circulatory system

• sense and respond to changes in the body and environment

What system is shown in the picture?

• Nervous System

• Circulatory System

• Muscular System

• Skeletal System

The breakdown of food into small molecules, which are then absorbed into the body is the main function of which body system.

• integumentary system

• digestive system

• excretory system

• endocrine system

This human body system is a series of organs responsible for taking in oxygen and expelling carbon dioxide.

• nervous system

• integumentary system

• respiratory system

• excretory system

Which body system converts food into simpler substances for the body to absorb as nutrients?

• Digestive system

• Excretory system

• Circulatory system

• Muscular system

The main function of the circulatory system is to -

• support and protect delicate organs such as the brain, lungs, and hear

• protect the body against invading organisms and infectious diseases

• pump oxygen and nutrients through the blood to every part of the body

• coordinate all actions and reactions of the body using electrical signals

_________ are absorbed into the blood.

• saliva

• gastric juices

• bile

• nutrients

Which body system is shown here?

• circulatory system

• respiratory system
