• Lungs

What is the purpose of pulmonary circulation in the circulatory system?

• Delivering oxygen and nutrients to tissues

• Returning deoxygenated blood to the left side of the heart

Which loop carries oxygenated blood from the left side of the heart to the rest of the body?

• Pulmonary Vein

• Pulmonary Circulation

• Systemic Circulation

• Pulmonary Artery

Why is understanding the left and right sides of the heart essential?

• To appreciate the heart's intricate design

• To grasp how the heart manages both pulmonary and systemic circulation

• To learn about the external features of the heart

• To understand the role of valves in the heart

Which part of the heart is responsible for initiating the electrical signals that regulate the heartbeat?
