The main function of the circulatory system is to:

• transport nutrients and oxygen to cells

• digest food

• control body temperature

• produce hormones

The circulatory system delivers more oxygen to the blood by:

• increasing heart rate

• decreasing blood pressure

• reducing blood volume

• slowing down the heart rate

The circulatory system interacts with the respiratory system by:

• transporting oxygen from the lungs to the body cells and carbon dioxide from the body cells to the lungs

• digesting food and absorbing nutrients

• producing hormones that regulate metabolism

• controlling voluntary and involuntary actions

The circulatory system interacts with the excretory system by:

• transporting nutrients to the kidneys for filtration

• removing waste products from the body through urine

• delivering oxygen to the excretory organs

• regulating body temperature through sweat

The two parts of the circulatory system responsible for transporting nutrients and oxygen in the blood are:

• arteries and veins

• heart and lungs

• capillaries and veins

• arteries and capillaries

The function of the respiratory system is to:

• transport nutrients throughout the body

• regulate body temperature

• exchange gases between the body and the environment

• digest food

The respiratory system exchanges which gases?

• Oxygen and Carbon Dioxide

• Nitrogen and Oxygen

• Carbon Dioxide and Nitrogen

• Hydrogen and Oxygen

The respiratory system interacts with the circulatory system by:

• exchanging gases in the lungs and transporting oxygen to cells

• digesting food and absorbing nutrients

• producing hormones and regulating metabolism

• filtering waste from the blood and excreting it

The primary role of the digestive system is to:

• break down food and absorb nutrients

• circulate blood throughout the body

• control body movements

• regulate body temperature
