What is the blood vessel that carries blood to the heart?
A vein
1 of 17
What is the blood vessel that carries blood away from the heart?
An artery
2 of 17
Which side of the heart is deoxygenated?
Right Side
3 of 17
Where does the oxygenated blood come from?
From the lungs, out through the aorta to the rest of the body
4 of 17
What is the name of the vein that takes the deoxygenated blood into the heart?
Vena Cava
5 of 17
In diastole, an atrium is filled by deoxygenated blood. Which one?
Right atrium
6 of 17
What happens before the right ventricle can be filled?
The tricuspid valve opens (atrioventricular)
7 of 17
Once the ventricle is full, another valve opens. Name it.
Semi-lunar valve.
8 of 17
Which artery takes the blood away to the rest of the lungs to become oxygenated?
Pulmonary artery.
9 of 17
Sum up the cycle of deoxygenated blood.
From body to vena cava, through right atrium, tricuspid valve, right ventricle, up through semi lunar valve, out through pulmonary artery, lungs.
10 of 17
When the blood is oxygenated, how does it travel from the lungs to the heart?
Through the pulmonary vein.
11 of 17
In the heart, which side does it enter?
Left side.
12 of 17
What is the valve called that the blood must flow through to get from left atrium to ventricle?
Bicuspid or atrioventricular
13 of 17
What artery is used to take blood to the extremities of the body?
The aorta
14 of 17
Why does the left ventricle have thicker walls?
It has to pump blood up the heart by contraction and ventricular systole. It also has to force all of the blood into the aorta, to be taken to the extremities of the body. There is a higher pressure.
15 of 17
What is the importance of the heart valves?
They prevent backflow of blood
16 of 17
How does pressure affect a valve's opening or closing?
If the pressure is high behind the valve, the valve is forced open so it is convex. However, if the pressure is high in front of the valve, it is forced shut - concave.
