The main function of the circulatory system is 

• To give the body structure and support

• Excrete waste

• transport blood, nutrients, and gases throughout the body

• to transport messages from the body to the brain

Running is an activity that causes the cells in the muscular system to use oxygen at a faster rate. Which system responds by delivering more oxygen to these cells?

• digestive

• nervous

• circulatory

• endocrine

It consists of...

• the heart, which is a muscular pumping device.

• the heart, which is a muscular pumping device, and a closed system of vessels called arteries and capillaries.

• the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.

The large muscle that contracts and relaxes and moves air in and out of the lungs.

• epiglottis

• alveoli

• diaphragm

• trachea

What is the main function of the respiratory system?

• to provide oxygen and remove carbon dioxide from the body

• to bring oxygen to the body

• to break down food and absorb nutrients

• to remove oxygen from the body and deliver carbon dioxide

What is the purpose of the respiratory system?

• takes in oxygen and release carbon dioxide

• takes in carbon dioxide and releases oxygen

• takes in nitrogen and releases carbon dioxide

• takes in oxygen and releases nitrogen

How do the Circulatory and Respiratory Systems work together?

• you inhale oxygen, your blood delivers that oxygen to your cells and brings CO2 back to lungs to exhale

• your circulatory and respiratory systems don't work together

• the circulatory system helps your respiratory system digest food
