Total questions: 15
Worksheet time: 8mins
Which chamber of the heart receives oxygen-poor blood from the body?
Left atrium
Right atrium
Left ventricle
Right ventricle
What is the name of the valve that allows blood to flow from the right atrium to the right ventricle?
Mitral valve
Tricuspid valve
Pulmonary valve
Aortic valve
Through which blood vessels does oxygen-poor blood enter the right atrium?
Pulmonary veins
Aorta
Superior and inferior vena cava
Pulmonary artery
Where does blood go after it leaves the right ventricle?
Aorta
Pulmonary artery
Left atrium
Pulmonary vein
Which chamber receives oxygen-rich blood from the lungs?
Right atrium
Left atrium
Right ventricle
Left ventricle
What is the function of the mitral valve?
Prevents backflow from the right ventricle to the right atrium
Allows blood to flow from the left atrium to the left ventricle
Prevents blood from entering the pulmonary artery
Allows blood to flow from the right atrium to the right ventricle
Which artery carries oxygen-rich blood from the heart to the body?
Pulmonary artery
Aorta
Superior vena cava
Inferior vena cava
What happens to blood in the lungs?
It loses oxygen and gains carbon dioxide
It gains oxygen and loses carbon dioxide
It becomes oxygen-poor
It is pumped to the right atrium
Which blood vessels return oxygen-rich blood from the lungs to the heart?
Pulmonary veins
Pulmonary arteries
Superior vena cava
Aorta
After blood leaves the left ventricle, through which valve does it pass before entering the aorta?
Tricuspid valve
Pulmonary valve
Mitral valve
Aortic valve
Arrange the following steps in the correct order for the flow of blood through the heart, starting with the right atrium: 1. Right ventricle 2. Left atrium 3. Lungs 4. Left ventricle
1, 3, 2, 4
1, 2, 3, 4
1, 4, 2, 3
1, 3, 4, 2
Explain why the left ventricle has a thicker wall than the right ventricle based on its function in blood circulation.
It pumps blood to the lungs, which requires more force.
It pumps blood to the entire body, requiring more force.
It only receives blood from the right atrium.
It does not pump blood at all.
If the tricuspid valve fails to function properly, which of the following is most likely to occur?
Blood will flow backward into the right atrium
Blood will not reach the lungs
Oxygen-rich blood will mix with oxygen-poor blood in the left atrium
Blood will not enter the aorta
Which of the following best describes the main purpose of the pulmonary circulation?
To deliver oxygen-rich blood to the body
To remove waste products from the body
To exchange carbon dioxide for oxygen in the lungs
To pump blood into the aorta
A blockage in the pulmonary artery would most directly affect which part of the blood flow process?
Blood entering the right atrium
Blood reaching the lungs for oxygenation
Blood returning to the left atrium
Blood leaving the left ventricle
