Pulmonary artery
Aorta
Vena cava
What is the main function of valves in the heart?
To add oxygen to blood
To prevent backflow of blood
To contract the heart
To carry blood away from the heart
Why is the wall of the left ventricle thicker than the right?
It pumps blood to the lungs
It pumps blood around the whole body
It contains more valves
It receives more blood
Which of these shows the correct pathway of blood through the heart and lungs?
Body → Left atrium → Right ventricle → Lungs
Body → Right atrium → Right ventricle → Lungs → Left atrium → Left ventricle → Body
Lungs → Right atrium → Left ventricle → Body
Left atrium → Right atrium → Lungs → Body
What is the function of the coronary arteries?
To supply the heart muscle with oxygenated blood
To remove carbon dioxide from the lungs
To carry blood to the brain
To transport urea to the kidneys
What happens to your heart rate during exercise?
It decreases to conserve energy
It increases to deliver more oxygen to muscles
It stays the same
It stops briefly
Which of the following substances is transported by the blood?
Oxygen
Glucose
Carbon dioxide
All of the above
Deoxygenated blood leaves the (a) through the (b) and travels to the lungs to get rid of (c) and pick up (d)
Oxygenated blood returns to the heart by way of the (a) entering the (b)
In the heart, oxygenated blood is moves from the (a) into the (b)
Oxygenated blood leaves the heart via the (a) to travel to the rest of the body.

What is the function of the heart in the circulatory system?
To pump oxygenated blood to the body's tissues
To carry deoxygenated blood from the body's tissues to the lungs
To exchange nutrients, oxygen, and waste products with tissues
To return blood from the body to the lungs
Explain the role of the heart in double circulation.
The heart circulates blood in a single loop system.
The heart separates oxygenated and deoxygenated blood, facilitating efficient double circulation.
The heart has no role in separating blood types.
The heart pumps only deoxygenated blood to the lungs.
How does the structure of the heart support double circulation?
The heart pumps blood in a single loop to the lungs and body.
The heart has only two chambers for efficient blood flow.
The heart's valves prevent blood from mixing, but do not support double circulation.
The heart's four chambers separate oxygenated and deoxygenated blood, supporting double circulation.
