Total questions: 13
Worksheet time: 11mins
What is the primary function of the heart in the circulatory system?
To produce blood cells
To pump blood throughout the body
To filter waste from the blood
To store oxygen
Which of the following best describes the difference between the atria and the ventricles?
Atria are larger than ventricles
Atria receive blood, while ventricles pump blood out
Atria pump blood to the lungs, while ventricles pump blood to the body
Atria are responsible for oxygenating blood, while ventricles are not
Label the chambers of the heart.
Trace the path of blood flow starting from the right atrium. Which of the following is the correct sequence?
Right atrium → Right ventricle → Lungs → Left atrium → Left ventricle
Right atrium → Left ventricle → Lungs → Right ventricle → Left atrium
Right atrium → Lungs → Right ventricle → Left atrium → Left ventricle
Right atrium → Left atrium → Right ventricle → Lungs → Left ventricle
Organize parts of the circulatory system by the kind of blood they carry
Most Veins
Right Atrium
Right Ventricle
Pulmonary Artery
Most Arteries
Vena Cava
Left Atrium
Left Ventricle
Pulmonary Vein
Aorta
What role do the heart valves play in blood circulation?
They oxygenate the blood
They prevent the backflow of blood
They increase the speed of blood flow
They filter impurities from the blood
Which type of blood is carried by the pulmonary veins?
Deoxygenated blood
Oxygenated blood
Mixed blood
Carbonated blood
Identify the chamber of the heart that receives deoxygenated blood from the body.
Left atrium
Right atrium
Left ventricle
Right ventricle
Which valve is located between the left atrium and the left ventricle?
Tricuspid valve
Pulmonary valve
Bicuspid valve
Aortic valve
What happens to blood as it passes through the lungs?
It becomes deoxygenated
It releases carbon dioxide and picks up oxygen
It becomes thicker
It loses nutrients
Which chamber of the heart pumps oxygenated blood to the rest of the body?
Right atrium
Right ventricle
Left atrium
Left ventricle
How does the structure of the ventricles support their function in the heart?
They have thinner walls to allow for faster blood flow
They have thicker walls to pump blood with more force
They are smaller to conserve space in the chest cavity
They have more valves to prevent backflow
Match Heart Diseases
Atherosclerosis
Clogging of arteries with fat
Heart Attack
When heart muscle itself lacks oxygen
Aneurysm
Dangerous ballooning out of an artery
Fibrillation
Heartbeat that is too rapid, just shakin
