Where does pulmonary circulation start?

• Right atrium

• Right ventricle

• Left atrium

• Left ventricle

What is the next step after blood flows into the right ventricle?

• It enters the systemic circulation

• It flows into the left atrium

• It is pumped into the pulmonary trunk

• It enters the aorta

What is the function of pulmonary capillaries?

• Drain blood into the right atrium

• Surround alveoli for gas exchange

• Transport blood to the heart

• Carry blood to the systemic circulation

What surrounds the alveoli where gas exchange occurs?

• Pulmonary arteries

• Pulmonary capillaries

• Pulmonary arterioles

• Pulmonary veins

What happens to carbon dioxide during gas exchange in the alveoli?

• It remains in the capillaries

• It enters the blood

• It is converted to oxygen

• It enters the alveoli

What happens to oxygen during gas exchange in the alveoli?

• It enters the alveoli

• It is converted to carbon dioxide

• It remains in the capillaries

• It enters the blood

Where does oxygen-rich blood go after leaving the pulmonary veins?

• Right atrium

• Left atrium

• Right ventricle

• Pulmonary trunk

What completes the pulmonary circuit?

• Pulmonary arterioles

• Pulmonary veins

• Pulmonary capillaries

• Pulmonary arteries

What is the role of the aorta in systemic circulation?

• It carries blood to the lungs

• It carries blood to the pulmonary veins

• It carries blood to the heart

• It carries blood to the body

What percentage of blood follows a different path, bypassing the pulmonary capillaries?

• 10%
