Understanding the Double Circulation System of the Human Heart

What is the primary function of the pulmonary circulation in the human heart?

• To distribute nutrients to the heart

• To deliver oxygenated blood to the body

• To remove waste products from tissues

• To oxygenate deoxygenated blood

Which valve does blood pass through when moving from the right atrium to the right ventricle?

• Mitral valve

• Pulmonary valve

• Tricuspid valve

• Aortic valve

During systemic circulation, through which valve does oxygen-rich blood pass from the left atrium to the left ventricle?

• Aortic valve

• Mitral valve

• Pulmonary valve

• Tricuspid valve

What is the role of capillaries in the systemic circulation?

• To filter waste products from the blood

• To exchange oxygen and nutrients with tissues

• To carry deoxygenated blood to the heart

• To pump blood to the lungs

What is the main purpose of the double circulation system in the human heart?

• To ensure efficient oxygenation and nutrient delivery

• To increase blood pressure

• To reduce heart rate

• To prevent blood clotting
