Science Quiz: Circulatory & Respiratory System

What is the main function of the heart in the circulatory system?

• Filtering waste from the blood

• Regulating body temperature

• Producing hormones for the body

• Pumping blood to circulate throughout the body

Explain the structure of the heart and how it facilitates its function.

• The heart is made up of three chambers - two atria and one ventricle, along with blood vessels. The atria pump blood out to the body and the ventricle receives blood. The valves prevent blood from entering the heart.

• The heart consists of five chambers - three atria and two ventricles, along with valves and blood vessels. The atria pump blood to the body and the ventricles receive blood. The valves regulate the flow of blood.

• The structure of the heart includes four chambers - two atria and two ventricles, along with valves and blood vessels. The atria receive blood and the ventricles pump blood out to the body. The valves prevent backflow of blood. This structure allows the heart to efficiently pump oxygenated blood to the body and deoxygenated blood to the lungs for oxygenation.

• The heart has two chambers - one atrium and one ventricle, along with blood vessels. The atrium pumps blood to the lungs and the ventricle receives blood from the body. The valves control the flow of blood.
