LECT 29. continuation of blood pressure, cardiovascular system and heart function Flashcards
what is atherosclerosis
build up of fats,cholesterol, and substances on artery walls
how does atherosclerosis affect blood pressure
the plaque causes narrowing of ateries causing peripheral resistance = increased blood pressure
how does Type 2 diabetes cause Atherosclerosis
higher than normal levels of lipids/fats in the blood can cause the formation of the plaque
Which of the following is NOT a likely outcome of taking anti-clotting drugs (also called blood thinners) preventatively?
a. Increased risk of severe nosebleeds
b. Decreased risk of hemorrhagic stroke
c. Decreased risk of ischemic stroke
d. Increased bruising
e. Decreased risk of heart attack
b. Decreased risk of hemorrhagic stroke
Due to blood leak so
blood thinners
increase risk
what can occur if clots block blood flow to the brain
ischemic stroke
what can occur if clots block blood flow to the brain
ischemic stroke
what occurs if clots block blood flow to heart
heart attack
What do you predict are risk factors for deep vein
thrombosis?
a. Compression socks
b. Not moving skeletal muscles in the leg
c. Increased vasoconstriction in the veins
d. Taking a blood thinner
e. Increased estrogen levels
b. Not moving skeletal muscles in the leg
e. Increased estrogen levels
If your DHP receptor was no longer physically
connected to the ryanodine receptor in skeletal
muscles in your leg, which of the following would
be likely?
a. Blood would flow backwards from the veins to
the arteries
b. Blood would pool in the veins of the leg
c. Blood flow back to the heart would be increased
d. Blood glucose levels would increase
b. Blood would pool in the veins of the leg
When you have your blood pressure taken at the doctor’s office, they don’t
want you to cross your legs. Why?
a. It will lead to a higher reading of your blood pressure
b. It will lead to a lower reading of your blood pressure
a. It will lead to a higher reading of your blood pressure
Which of the following would decrease your blood pressure
a. Increase heart rate
b. Decrease stroke volume
c. Increase fluid intake
d. Increased plaque buildup
b. Decrease stroke volume
what are the two cycles of the cardiac cycle
diastole and systole
what is the diastole cycle
the time during the cardiac muscle relaxes
filling
what is the systole cycle?
pumping
the time during which the muscle contracts
what does stroke volume represent
volume of blood ejected from ventricle with each heartbeat
