Multiple Choice - Human Organs

During a science class, Kayden and Amariah were discussing the human brain. They wondered which of the following functions the brain is responsible for?

• Fighting the body’s diseases

• Breaking down food nutrients

• Controlling muscle movement

• Pumping blood through the body
