• 1

• Left atrium
• Right atrium
• Left ventricle
• Right ventricle

Which part of the heart pumps deoxygenated blood into the pulmonary arteries?

• Left atrium

• Right atrium

• Left ventricle

• Right ventricle

What is the primary function of arteries?

• Carry oxygen-rich blood away from the heart

• Carry oxygen-poor blood to the heart

• Exchange gases and nutrients

• Connect to veins

What do veins do in the circulatory system?

• Carry oxygen-rich blood away from the heart

• Exchange gases and nutrients

• Carry low oxygen blood back to the heart

• Connect arteries to capillaries

Which vessels carry blood to the heart?

• Veins
• Arteries
• Capillaries

What is the main function of systemic circulation?

• To supply oxygenated blood to the lungs

• To transport blood to and from all the tissues of the body

• To pump deoxygenated blood to the heart

• To exchange gases in the lungs

What is the role of capillaries in the vascular network?

• Carry blood away from the heart

• Exchange gases, nutrients, and waste products

• Carry blood back to the heart

• Prevent backflow of blood

What is the role of the vena cava in the cardiovascular system?

• To carry oxygen-rich blood to the heart

• To carry oxygen-poor blood to the heart

• To distribute blood to the body

• To exchange gases in the lungs

What happens when the atria contract?

• The ventricles open

• The valves close

• The valves open

• The heart stops
