HBIO202 FINAL EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS GRADED A++
systemic circuit
carries blood between the heart and the rest of the body
pulmonary circuit
carries blood to and from lungs
arteries
blood vessels that go away from the heart
veins
blood vessels that go towards the heart
capillaries
smaller blood vessels that connects arterioles and venules
arteriosclerosis
walls of arteries become thick and stiff which then restrict blood flow to organs and
tissues
atheroscelerosis
most common form of arteriosclerosis
coronary heart disease
- supplies oxygen rich blood to heart
- reducing diameter can damage tissue which can lead to heart attacks
How does arteriosclerosis form?
, 1. accumulation of LDL cholesterol in arteries
2. plaque forms
3. scarring of plaque causes stiffness
4. plaque develops blood clots
Carotid Artery disease
delivers blood to brain
- plaque can break off and block arteries causing a stroke
peripheral arterial disease
- narrowing of arteries in limbs
- can change color and cause ulcers
- gangrene and limb loss
Heart Failure
a chronic condition in which the heart is unable to pump out all of the blood that it
receives
Ejection Fraction
how much blood gets into the heart and gets expelled
lipids
category of compound containing carbon, hydrogen, oxygen
- Note: hydrophobic
vitamins
Compounds found in food that help regulate many body processes
Free radicals
