What is the difference between systemic and pulmonary circulation?

• Systemic circulation carries deoxygenated blood from the heart to the body; pulmonary circulation carries oxygenated blood from the heart to the lungs.

• Systemic circulation carries oxygenated blood from the heart to the body; pulmonary circulation carries deoxygenated blood from the heart to the lungs.

• Systemic circulation is responsible for nutrient absorption; pulmonary circulation is responsible for waste removal.

• Systemic circulation occurs only during exercise; pulmonary circulation occurs at rest.

What type of blood do veins typically carry?

• Oxygenated blood

• Deoxygenated blood, except for pulmonary veins.

• Nutrient-rich blood

• Carbon dioxide-rich blood

Is the blood carried by the aorta oxygenated or deoxygenated?

• Oxygenated.

• Deoxygenated.

• Partially oxygenated.

• Carbonated.

What does 'ventral' refer to in anatomical terms?

• Back.

• Top.

• Side.

• Front.

What is the role of the left atrium in the heart?

• To receive oxygenated blood from the lungs.

• To pump deoxygenated blood to the lungs.

• To regulate blood pressure in the arteries.

• To store blood before it enters the ventricles.

What is the significance of the septum in the heart?

• It separates the left and right sides of the heart, preventing mixing of oxygenated and deoxygenated blood.

• It regulates the heart rate by controlling electrical impulses.

• It pumps blood to the lungs for oxygenation.

• It stores excess blood before it is pumped to the body.

What is the function of arteries and veins in the circulatory system?

• Arteries bring blood towards the heart; veins bring blood away from the heart.

• Arteries bring oxygenated blood to the lungs; veins bring deoxygenated blood to the heart.

• Arteries bring blood away from the heart; veins bring blood towards the heart.

• Arteries and veins both carry blood in the same direction.

What is the role of the right atrium?

• To pump oxygenated blood to the body.

• To receive deoxygenated blood from the body via the superior and inferior vena cavae.

• To filter blood before it enters the lungs.

• To store blood before it is pumped to the heart.

What is the function of the pulmonary veins?

• To carry deoxygenated blood from the body to the heart.

• To carry oxygenated blood from the lungs to the left atrium.

• To transport carbon dioxide from the heart to the lungs.

• To circulate blood throughout the body.

Which of the following contains oxygenated blood: right ventricle, pulmonary artery, superior vena cava, or left atrium?

• Right ventricle

• Pulmonary artery

• Superior vena cava

• Left atrium
