2nd review- Circulatory System

What are the four main chambers of the heart?

• right atrium, left atrium, right ventricle, aorta

• right atrium, left ventricle, pulmonary artery, aorta

• right atrium, right atrial appendage, left atrial appendage, left ventricle

• right atrium, right ventricle, left atrium, left ventricle

What is the function of the aorta?

• The aorta carries deoxygenated blood to the heart.

• The aorta is responsible for filtering blood in the kidneys.

• The aorta regulates blood pressure in the lungs.

• The aorta carries oxygenated blood from the heart to the body.

Name the blood vessel that carries oxygen-rich blood away from the heart.

• pulmonary artery

• vena cava

• capillaries

• aorta

What is the role of veins in the circulatory system?

• Veins transport deoxygenated blood back to the heart.

• Veins carry oxygenated blood away from the heart.

• Veins are responsible for pumping blood throughout the body.

• Veins filter toxins from the blood before it reaches the heart.

Describe the process of pulmonary circulation.

• Pulmonary circulation only occurs during exercise and not at rest.

• Pulmonary circulation transports deoxygenated blood from the right heart to the lungs for oxygenation and returns oxygenated blood to the left heart.

• Pulmonary circulation is responsible for nutrient absorption in the intestines.

• Pulmonary circulation carries oxygenated blood from the left heart to the body.

What component of blood is responsible for transporting oxygen?

• Hemoglobin

• White blood cells

• Plasma

• Platelets

What is the function of red blood cells?

• To fight infections and diseases.

• To store nutrients and vitamins.

• The function of red blood cells is to transport oxygen and carbon dioxide.

• To produce insulin for the body.

How does the heart pump blood throughout the body?

• The heart pumps blood by filtering it through the lungs.

• The heart pumps blood by expanding and contracting the lungs.

• The heart pumps blood by using electrical signals to push it out.

• The heart pumps blood by contracting and relaxing, moving blood through the circulatory system.

What are capillaries and why are they important?

• Capillaries are small blood vessels that enable the exchange of substances between blood and tissues, making them essential for nutrient delivery and waste removal.

• Capillaries are primarily involved in the production of red blood cells.

• Capillaries are responsible for pumping blood throughout the body.

• Capillaries are large blood vessels that carry oxygenated blood only.

What is the difference between arteries and veins?

• Arteries are thinner than veins; veins are thicker than arteries.

• Veins transport oxygenated blood; arteries transport deoxygenated blood.

• Arteries carry blood away from the heart; veins carry blood to the heart.

• Arteries transport oxygenated blood; veins transport deoxygenated blood.
