What is the name given to the upper two chambers of the heart?
atrium
The two upper cavities of the heart are called atria (plural for atrium). Deoxygenated blood is received into the right atrium, and the left atrium receives oxygenated blood..
ventricle
vein
artery

What is the name given to the lower two chambers of the heart?
atrium
ventricle
Blood from the right atrium enters the right ventricle and pumps it into the lungs, and blood from the left atrium enters the left ventricle where it gets pumped into the circulatory system.
vein
artery

What is the largest blood vessel in your body?
aorta
The aorta carries oxygenated blood from the heart to all the tissues in the body.
veins
artery
capillary

What is the smallest blood vessel in your body?
aorta
vein
artery
capillary
The average adult body has about 10 billion capillaries, which connect arteries and veins.

The coronary artery is important for supplying the heart with blood. If it is blocked or narrowed, coronary artery disease can occur. This is the most common cause of heart disease.
hyperthermia
torn muscle

What is it called when your arteries harden and get narrow?
atherosclerosis
Damage to the lining of the blood vessel by high blood pressure, smoking, or high cholesterol can lead to the formation of plaques in your arteries that can clog the way for blood.
stroke
apoptosis
cancer

What is inside an atherosclerotic plaque?
celery
cheese
hamburgers
cholesterol deposits
Plaques start as a fatty streak on the inside of the blood vessel, and can progress to a calcified plaque.

What is a condition in which the force of the blood against the artery walls is too high?
liver failure
kidney damage
high blood pressure
Also called hypertension, high blood pressure is defined as a blood pressure above 140/90. A healthy blood pressure is generally considered at or below 120/80.
crow's feet

What is improper beating of the heart, whether irregular, too fast, or too slow?
arrhythmia
Arrhythmia refers to any change in the electrical impulses of the heart that deviate from the normal sequence. This can lead to the inability of the heart to pump blood efficiently.
palpitation
shock
broken

What is a circulatory condition in which narrowed blood vessels reduce blood flow to the limbs?
numbness
stroke
peripheral artery disease
Peripheral artery disease most commonly occurs in the legs.
heart attack

What is damage to the brain from interruption of its blood supply?
seizure
heart attack
stroke
A stroke is a kind of "brain attack" - the cells of the brain can die because if blood flow is cut off, then the cells do not receive oxygen and cannot survive.
anemia

Cerebral infarction is one way to describe:
heart attack
stroke
A type of ischemic stroke resulting from a blockage in the blood vessels that supply blood to the brain is called a cerebral infarction.
cancer
pulled muscle

How does one describe a blue skin color caused by lack of oxygen?
cyanotic
The word "cyan" comes from the Greek word for blue: kyan├│s.
non-cyanotic
blue
bruised

What is a chronic condition in which the heart doesn't pump blood as well as it should.
arrythmia
congestive heart failure
There are two types of heart failure, diastolic and systolic.
stroke
ischemia

Advertisement

Diastolic congestive heart failure occurs when the heart:
cannot fill
In diastolic heart failure, the muscle of the left ventricle has become stiff and cannot relax, resulting in an inability to fill with blood properly.
cannot pump
breaks
shrinks

Advertisement

Systolic congestive heart failure occurs when the heart:
cannot fill
cannot pump
In systolic heart failure, the left ventricle cannot contract normally, so enough blood cannot get pushed into circulation and maintain a healthy body.
breaks
shrinks

What is angina?
a flightless bird
candy
chest pain
Angina is chest pain caused by a lack of oxygen-rich blood flow to the heart. It can feel like pressure in your chest or indigestion.
stroke

Heart attack is the more common way to describe:
stroke
myocardial infarction
The myocardium is the muscular tissue of the heart, and an infarction is the obstruction of the blood supply.
arrhythmia
cancer
