What are the three main functions of the circulatory system?

• Transporting substances, controlling body temperature, protecting the body

• Digesting food, controlling body temperature, protecting the body

• Transporting substances, digesting food, protecting the body

• Transporting substances, controlling body temperature, producing energy

The circulatory system transports substances like oxygen, glucose, carbon dioxide, nutrients, water, waste products.

True or False.

• True

• False

How does the circulatory system help in protecting the body?

• By transporting oxygen and nutrients

• By controlling body temperature

• By containing white blood cells and antibodies that fight infection and Platelets (clotting agents) to stop bleeding

• By producing energy

Why is the circulatory system described as a double system?

• Because it has two types of blood

• Because it has two loops

• Because it has two hearts

• Because it has two functions

What is one of the functions of the circulatory system related to body temperature?

• Transporting oxygen using red blood cells

• Controlling body temperature using evaporation at surface of skin

• Protecting the body using white blood cells

• Producing energy through cellular respiration in the cells.
