Categorize the following descriptions and functions to the correct system.

Groups:

(a) Circulatory System

,

(b) Respiratory System

• Consists of lungs and airways

• Consists of blood, veins, arteries, and the heart

• delivers oxygen to the body tissues and removes carbon dioxide produced by metabolism

• Consists of organs that allow people to breathe, taking in oxygen and expelling carbon dioxide

The ​ (a)   system consists of blood, veins, arteries, and the heart.

• Respiratory

• Digestive

• Nervous

• circulatory

Which function does not apply to the circulatory system?

• The circulatory system moves blood between the heart and the rest of the body.

• The circulatory system circulates oxygen to the body’s cells and removes carbon dioxide.

• The circulatory system filters the blood.

• The circulatory system provides nutrients to the body’s cells.

Look at the image of a body system. The ​ (a)   system is shown in the image. The primary function of this body system is to ​ (b)  

• digestive
• nervous
• circulatory
• respiratory
• exchange gases
• break down food
• send signals
• transport blood

The structures shown are part of the circulatory system. What functions of the circulatory system do these structures support?

• Regulates fluids, eliminates waste, regulates water

• Provides protection for organs, allows body movement, supports the body’s frame

• Delivers air into the body, removes carbon dioxide, delivers oxygen to circulatory system

• Transports oxygen and wastes, provides nutrients to the cells, pumps blood to the body

The primary function of the circulatory system is to​ ​ (a)   .

• digest food

• transport nutrients and oxygen
• produce hormones

• regulate temperature

When people run for exercise, their muscles need more oxygen. Which systems are responsible for carrying oxygen from the air and transporting it to the muscles?

• Nervous

• Digestive

• Respiratory

• Circulatory

The main difference between the functions of the two systems is that the respiratory system is responsible for ​ (a)   oxygen, while the circulatory system is responsible for ​ (b)   it throughout the body.

• absorbing

• transporting
• storing

• producing

• taking in
