5D - Circulatory System Revision

The circulatory system is made up of:

• Lungs

• Heart

• Blood

• Blood vessels

• All of the above

How is blood circulated in the circulatory system?

• It is first pumped to the lungs, back to the heart and then to the rest of the body.

• It is first pumped to the rest of the body, back to the lungs and then to the heart.

• It is pumped to the rest of the body, back to the heart and then to the lungs.

The function of the blood is to:

• Transports carbon dioxide, digested food and water to all parts of the body and takes away oxygen and waste material from all parts of the body.

• Transports only oxygen to all parts of the body and takes away only carbon dioxide from all parts of the body.

• Transports oxygen, digested food and water to all parts of the body and takes away carbon dioxide and waste material from all parts of the body.

• Transports oxygen, waste material and water to all parts of the body and takes away carbon dioxide and digested food from all parts of the body.
