Question 1

What are the main components of the cardiovascular system

Answer 1

• Heart
• Blood vessels
• Blood

Question 2

What are the two types of circulation in the cardiovascular system

Answer 2

• Pulmonary circulation
• Systemic circulation

Question 3

What is pulmonary circulation

Answer 3

• Carries blood between heart and lungs
• Deoxygenated blood leaves the right ventricle through pulmonary arteries, which transports it to the lungs
• In the lungs, the blood gives up carbon dioxide and picks up oxygen
• The oxygenated blood then returns to the left atrium of the heart through pulmonary veins

Question 4

What is systemic circulation

Answer 4

• Carries blood between heart and body
• Oxygenated blood leaves the left ventricle though the aorta
• The aorta and other arteries transport the blood throughout the body, where it gives up oxygen and picks up carbon dioxide
• The deoxygenated blood then returns to the right atrium through veins

Question 5

List the parts of the heart

Answer 5

• Left ventricle
• Right ventricle
• Left atrium
• Right atrium
• Pulmonary vein (blood from the lungs)
• Vena cava (blood from the body)
• Pulmonary artery (blood to the lungs)
• Aorta (blood to the body)
