Cardiovascular System

What is the first chamber of the heart that receives deoxygenated blood from the body?

• Right Atrium

• Left Atrium

• Right Ventricle

• Pulmonary Vein

What is the role of plasma in the blood?

• Plasma is the solid component of blood that helps in clotting.

• Plasma is the liquid component of blood that carries cells, nutrients, hormones, and waste products.

• Plasma is responsible for the immune response in the blood.

• Plasma is the component of blood that stores oxygen.

What cells give blood its red color and carry oxygen?

• White Blood Cells

• Platelets

• Red Blood Cells

• Plasma Cells

Which arteries bring deoxygenated blood from the pulmonary trunk to the left lung?

• Left Pulmonary Arteries

• Right Pulmonary Arteries

• Aorta

• Coronary Arteries

What is the function of capillaries in the cardiovascular system?

• Capillaries transport blood away from the heart.

• Capillaries are small blood vessels where the exchange of oxygen, carbon dioxide, nutrients, and waste occurs.

• Capillaries are responsible for pumping blood throughout the body.

• Capillaries store excess blood for later use.

What is the role of the aorta in the cardiovascular system?

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

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

• To regulate blood pressure in the arteries.

• To filter waste products from the blood.

What is the function of the right atrium?

• Pumps oxygenated blood to the body.

• Receives deoxygenated blood from the body via the inferior and superior vena cavas.

• Filters toxins from the blood.

• Regulates blood pressure in the arteries.

What is the largest blood vessel in the body that carries oxygenated blood from the left ventricle to the rest of the body?

• Pulmonary artery

• Aorta

• Superior vena cava

• Coronary artery

What is the difference between arteries and veins?

• Arteries carry blood towards the heart, while veins carry blood away from the heart.

• Arteries carry oxygenated blood, while veins carry deoxygenated blood.

• Arteries carry blood away from the heart, while veins carry blood back to the heart.

• Arteries are thicker than veins, but both carry blood in the same direction.

What is the significance of the inferior and superior vena cavas?

• They are large arteries that carry oxygenated blood to the body.

• They are large veins that bring deoxygenated blood from the body back to the right atrium.

• They are small veins that transport nutrients to the heart.

• They are valves that regulate blood flow in the heart.
