Circulatory System Grade 9

What is the process involved in the transport of oxygenated blood and nutrients throughout the cells?

• Digestion

• Respiration

• Absorption

• Circulation

Which structure carries the oxygenated blood away from the heart to the cells of the body?

• Artery

• Heart

• Vein

• Blood

Which of the following is not part of the human circulatory system?

• Heart

• Lungs

• Blood

• Blood vessels

What happens to the blood when it is pumped into pulmonary artery?

• The blood returns to the left atrium of the heart

• The blood moves through a capillary, nutrients, oxygen and food leave the blood and enter the body cells

• The blood separates its components and combines with oxygen

• The blood travels to the lungs, where it releases carbon dioxide and receives oxygen

Which of the following parts of the human heart contains oxygenated blood?

• Right atrium

• Right ventricle

• Left atrium

• Pulmonary artery

Which of the following series represents the correct path of blood circulation?

• Right atrium, left atrium, lungs, right ventricle, left ventricle

• Right atrium, right ventricle, lungs, left atrium, left ventricle

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

• Right ventricle, left atrium, right atrium, left ventricle, lungs

Once the blood move from atria down to ventricles, there are openings that let the blood pass through and close, so the blood cannot flow backwards into the atria. What do you call these openings?

• Septa

• Valves

• Capillaries

• Aorta

What happens to deoxygenated blood when it exits the right ventricle of the heart?

• The heart pumps it out of the right ventricle and move into the pulmonary arteries to begin pulmonary circulation

• It moves to the left ventricle of the heart

• The right ventricle pumps the deoxygenated blood to the aorta which will distribute to all parts of the body

• The heart pumps it out of the right ventricle and move into the left atrium

How are arteries different from veins?

• Arteries pump blood away from the heart; veins deliver and absorb oxygen, nutrients, and other substances.

• Arteries transport blood away from the heart; veins return blood back toward the heart

• Arteries produce blood; veins collect oxygen from the blood

• Arteries carry deoxygenated blood; veins carry oxygenated blood

What is organ that pumps blood all throughout the human body?

• Heart

• Blood vessels

• Kidney

• Aorta
