Heart Flow of Blood

From the body, blood enters

• the right ventricle

• the right atrium

• the left atrium

• the left ventricle

Blood goes to the lungs from the

• left ventricle

• left atrium

• right ventricle

• right atrium

Blood goes to the systemic circulation

• through the aorta

• through the pulmonary artery

• through the pulmonary vein

• through the right ventricle

The tricuspid valve is between

• the right ventricle and the pulmonary artery

• the right atrium and right ventricle

• the pulmonary artery and left ventricle

• the left atrium and left ventricle

When we inhale,

• oxygenated blood enters the lungs

• oxygen diffuses across the alveoli into the pulmonary arteries

• carbon dioxide diffuses across the alveioli into the pulmonary veins

• oxygen diffuses across the alveoli into the pulmonary veins

The left side of the heart

• separates oxygenated and deoxygenated blood before bringing it to the lungs

• pumps only deoxygenated blood

• pumps oxygenated blood only

• brings deoxygenated blood from the lungs to the body where it is oxygenated

Which ventricle is larger?

• left

• right

• upper

• lower

The left ventricle leads to the

• pulmonary veins and then the systemic circulation

• pulmonary artery and then the lungs

• aorta and then the lungs

• aorta and then the systemic circulation

Which of the below is correct? Note you have a full minute for this question.

• Pulmonary artery - left atrium - left ventricle - aorta; Vena cava - right atrium - right ventricle - pulmonary vein

• Vena cava - left atrium - left ventricle - pulmonary vein; Aorta - right atrium - right ventricle - pulmonary artery

• Pulmonary vein - left ventricle - left atrium; Aorta - right atrium - right ventricle

• Pulmonary vein - left atrium - left ventricle - aorta; Vena cava - right atrium - right ventricle - pulmonary artery
