What part of the heart is #1 pointing to?
The aorta
100
What is it called when a heart valve doesn't work properly?
Valve stenosis
100
Arteries are more elastic than veins.
True
200
What type of blood is the universal donor?
Type O
200
What is the normal range of diastolic blood pressure?
60-80mmHg
200
Where does the blood go after it leaves the right ventricle?
Pulmonary artery
200
Is the blood in the superior and inferior vena cava oxygenated or deoxygenated?
Deoxygenated.
200
The blood travales from the pulmonary veins to the left ventricle.
False
300
What are the main components of blood?
Plasma, red blood cells, white blood cells + platelets
300
What is systolic blood pressure?
It is pressure on arteries when the heart contracts.
300
Where was the blood before it entered the superior vena cava?
The head.
300
When the blood leaves the pulmonary artery where does it go?
The lungs.
300
White blood cells help defend the body from disease and infection
True
400
What is the main function of red blood cells?
Increases surface area, gas exchange across the membrane more efficient and their small flexible shape lets them squeeze through capillaries
400
What procedure can you get to widen clogged blood vessels?
An angioplasty
400
What part of the heart is #8 pointing to?

400
What is the purpose of the Purkinje fibers?
They send nerve impulses to the cells in the heart, which cause them to contract and pump blood to the lungs or rest of the body
400
Capillaries contain oxygenated and deoxygenated blood.
True
500
How do veins push blood to the heart?
They rely on surrounding skeletal muscles to squeeze the veins and push blood through the veins. If the muscle relaxes, valves in the vein close so the blood does not travel backward.
500
During what cycle of the cardiac cycle is blood pressure typically lowest?
Diastole
500
What part of the heart is #10 pointing to?
Pulmonary veins.
500
Where does the signal to start each heartbeat come from?
The sinoatrial (SA) node
500
Pulmonary arteries carry oxygenated blood to the heart.
False
