Circulatory System Quiz

What is the main function of the heart?

• Pumping blood

• Regulating body temperature

• Digesting food

• Filtering air

Explain the role of the atria and ventricles in the heart's structure.

• The atria and ventricles have no specific roles in the heart's structure.

• The atria receive blood from the body and lungs, while the ventricles pump blood out of the heart to the body and lungs.

• The ventricles receive blood from the body and lungs.

• The atria pump blood out of the heart to the body and lungs.

Describe the pathway of blood flow through the heart.

• Pulmonary artery, right atrium, tricuspid valve, right ventricle, pulmonary valve, lungs, pulmonary veins, left atrium, mitral valve, left ventricle, aortic valve, aorta

• Right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary veins, left atrium, mitral valve, left ventricle, aortic valve, aorta

• Left atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary veins, right atrium, mitral valve, left ventricle, aortic valve, aorta

• Right atrium, mitral valve, left ventricle, aortic valve, aorta, left atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary veins

What are the three types of blood vessels and their functions?

• Arteries, veins, and capillaries

• Aorta, pulmonary artery, vena cava

• Red blood cells, white blood cells, platelets

• Left atrium, right ventricle, pulmonary valve

How does oxygenated and deoxygenated blood circulate through the body?

• Through the digestive system

• Through the nervous system

• Through the skeletal system

• Through the circulatory system

Explain the difference between arteries and veins.

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

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

• Arteries and veins both carry oxygenated blood away from the heart.

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

What is the function of capillaries in the circulatory system?

• Exchange of oxygen, nutrients, and waste products

• Regulation of body temperature

• Storage of excess nutrients

• Transport of hormones and enzymes

Describe the process of systemic circulation.

• Oxygenated blood is pumped from the heart to the rest of the body through the arteries, and then returns deoxygenated blood back to the heart through the veins.

• The blood flows from the body to the heart through the arteries, and then returns to the body through the veins.

• Deoxygenated blood is pumped from the heart to the rest of the body through the veins, and then returns oxygenated blood back to the heart through the arteries.

• The heart pumps blood to the lungs to get oxygen, and then the oxygenated blood is distributed to the rest of the body through the veins.
