Left ventricle
Right ventricle
Left atrium
20s
Which blood vessel brings deoxygenated blood from the body back into the right atrium?
Aorta
Vena cava
Pulmonary vein
Pulmonary artery
20s
What is the main job of the valves in the heart?
To set the rhythm of the heartbeat
To stop blood flowing backwards
To push blood into the arteries
To add oxygen to the blood
20s
Why is the human circulatory system described as a double circulatory system?
The heart has two atria and two ventricles
Blood passes through the heart twice per circuit
Blood travels in both arteries and veins
The heart beats twice for every breath
30s
Which statement about the pulmonary vein is correct?
It carries deoxygenated blood to the left atrium
It carries deoxygenated blood to the lungs
It carries oxygenated blood to the left atrium
It carries oxygenated blood to the right atrium
30s
Why does the left ventricle have a thicker muscular wall than the right ventricle?
It receives blood straight from the body
It pumps blood at high pressure to the lungs
It holds a larger volume of blood
It pumps blood at high pressure around the body
30s
Where in the heart are the pacemaker cells that control the resting heart rate found?
In the right ventricle
In the left ventricle
In the left atrium
In the right atrium
30s
Which description best matches the structure of an artery?
Walls one cell thick and a tiny lumen
Thick muscular, elastic walls and a narrow lumen
Thin elastic walls and a wide lumen
Thin walls, a wide lumen and valves
30s
How does the structure of capillaries make them well suited to exchanging substances with cells?
Their walls are only one cell thick
Their thick walls stop blood leaking out
Their valves keep blood moving towards cells
Their elastic walls push substances into cells
30s
Why can coronary heart disease damage part of the heart muscle?
Fatty deposits block the vena cava
Fatty deposits narrow the coronary arteries
Faulty valves let blood leak back into the atria
Pacemaker cells stop sending electrical impulses
