Circulatory System (Q3)

Among the three components of the circulatory system, which one delivers essential nutrients to different parts of the body, fights off infection, and performs other significant tasks?

• Blood

• Blood vessels

• Heart

• Systole

What happens during systole?

• The heart relaxes; blood fills it up through the arteries.

• The heart relaxes, pumping blood out of it through the veins.

• The heart contracts; pumping blood out of it through the arteries

• The heart contracts; blood fills it up through the veins.

These are blood vessels that carries blood AWAY from the heart.

• Veins

• Arteries

• Capillaries

• Plasma

These are tiny blood vessels that allow the exchange of gases between the body cells and the blood. These blood vessels can be found in the alveoli of the lungs.

• Arteries

• Veins

• Valves

• Capillaries

What is the function of valve?

• Regulates the flow of blood and keeps it flowing in one direction

• Transports nutrients to cells needing it.

• It works with the body's immune system in fighting off infections

• Connects arteries and veins together

What blood vessels carry deoxygenated blood from the lower and upper parts of the body and bring them to the right atrium?

• vena cavas

• aorta

• pulmonary arteries

• pulmonary veins

What valve regulates the blood that enters the right ventricle and prevents it from flowing back to the right atrium?

• Mitral valve

• Tricuspid valve

• Aortic valve

• Pulmonary valve

These are blood vessels that carry blood towards the heart.

• Capillaries

• Arteries

• Valves

• Veins

This is an instrument used in measuring blood pressure.

• Barometer

• Anemometer

• Sphygmomanometer

• Odometer

Deoxygenated blood in the right ventricle is then pumped through the pulmonary arteries through what valve?

• Mitral

• Tricuspid

• Aortic

• Pulmonary
