Understanding Blood Flow in the Heart

What does the right atrium do with blood?

• The right atrium collects oxygenated blood from the lungs.

• The right atrium oxygenates blood before sending it to the lungs.

• The right atrium receives deoxygenated blood and pumps it into the right ventricle.

• The right atrium pumps blood directly to the aorta.

Where does the blood go after the right ventricle?

• Coronary artery

• Pulmonary artery

• Left atrium

• Aorta

What gas is replaced by oxygen in the lungs?

• Nitrogen

• Carbon dioxide

• Hydrogen

• Helium

Which chamber of the heart receives oxygen-rich blood from the lungs?

• Pulmonary artery

• Left atrium

• Left ventricle

• Right atrium

What is the function of the left ventricle?

• To pump deoxygenated blood to the lungs.

• To regulate blood pressure in the arteries.

• To receive blood from the right atrium.

• To pump oxygenated blood to the body.

How does blood flow from the right atrium to the right ventricle?

• Blood flows directly from the right atrium to the lungs without passing through the right ventricle.

• Blood flows from the right atrium to the left ventricle through the mitral valve.

• Blood is pumped from the right atrium to the right ventricle via the aorta.

• Blood flows from the right atrium to the right ventricle through the tricuspid valve.

What happens to carbon dioxide in the lungs?

• Carbon dioxide is stored in the lungs for later use.

• Carbon dioxide is expelled from the body during exhalation.

• Carbon dioxide is converted into oxygen in the lungs.

• Carbon dioxide is absorbed into the bloodstream.

What is the journey of oxygenated blood after it leaves the left ventricle?

• Oxygenated blood travels from the left ventricle to the aorta, then to systemic arteries, capillaries, and returns to the right atrium.

• Oxygenated blood moves directly to the brain before returning to the heart.

• Oxygenated blood goes from the left ventricle to the lungs, then to the left atrium.

• Oxygenated blood travels to the right ventricle, then to the pulmonary arteries.

Which part of the heart pumps blood to the body?

• Left atrium

• Left ventricle

• Right atrium

• Right ventricle

Why is oxygen important for blood?

• Oxygen is primarily used for digestion in the stomach.

• Oxygen is a waste product of cellular respiration.

• Oxygen helps in the formation of blood clots.

• Oxygen is crucial for cellular respiration and energy production in the body.
