What is heart rate?
High amounts of this lipoprotein increase your risk of heart disease.
What is LDL?
This is a sudden loss of consciousness, sensation and voluntary motion caused by a blood clot in the brain.
What is a stroke?
This determines how the DNA fragments separate during gel electrophoresis.
What is the length (or size) of the DNA fragment?
These vessels carry blood toward the heart, while these carry blood away from the heart.
What are veins and arteries?
This is a measure of the electrical activity in the heart.
What is electrocardiogram (EKG)?
A diet that helps keep blood cholesterol levels in check includes these.
What are vegetables, lean meats, and fruits?
This is the term for a procedure using dye and x-rays to provide an image of the heart’s blood vessels.
What is an angiogram?
This property of DNA causes it to migrate to the opposite pole of the electrophoresis chamber.
What is the negative charge of the phosphate groups?
This chamber has the thickest walls.
What is the left ventricle?
This is a measure of the push of blood on the artery walls when the heart is relaxed.
What is diastolic pressure?
Cholesterol belongs to this group of macro-molecules.
What is a lipid?

What is returning cholesterol to the liver for excretion?
The build-up of plaque inside the arteries is this.
What is artherosclerosis?

What is PCR?
Blood passes through the four valves of the heart in this order beginning in the right atrium.
What is: tricuspid, pulmonary, bicuspid (mitral), and aortic?
In terms of both flow and pressure, narrowing of the arteries will cause this.
What is decreased flow and increased pressure?
This is considered an acceptable level for HDL in your blood.
What is >60 mg/dL?
This class of drugs is used to treat high cholesterol. Anna had some in her system when she died.
What are statins?
An individual who is heterozygous for familial hypercholesterolemia would yield this many bands on an electrophoresis gel after RFLP analysis.
