Exercise 34: Blood Vessels and Blood Pressure

What is the clinical threshold for high blood pressure in young adults?

130/80

Emotions have an effect on blood pressure. Predict the blood pressure of an individual who recently had a heated argument with a roommate about rent money.

A recent argument would result in elevated blood pressure

The letters bpm stand for what phrase in cardiac measurement?

Beats per minute

What does a sphygmomanometer measure

Blood pressure

How did the change in blood pressure after exercise vary from those people who were in shape versus those who do not exercise?

Blood pressure is going to be higher if you are out of shape because you are more tired compared to someone in shape and your heart will be beating faster

To measure blood pressure, what artery would you most commonly use?

Brachial artery

If you have a blood pressure 140/80, what does the 80 represent?

Diastolic pressure

Illness an also affect blood pressures. Illness tends to increase stress responses. Predict the blood pressure of an individual with a sinus headache and a postnatal drip.

Since stress responses are increased and can result in elevated blood pressure, the blood pressure would be elevated

When the first sound is heard during measurement with a blood pressure cuff, what is measured-systolic or diastolic pressure?

Systolic pressure

Nicotine and caffeine both elevate blood pressure. Explain how an increase in blood pressure could have a negative effect on the cardiac output.

cause vasoconstriction which can cause elevated blood pressure which causes the heart to pump harder

As a result of your experiment described in review question 13, describe how arteriosclerosis and the accompanying decrease in a vessel's diameter causes changes in flow and/or pressure, and how this has an impact on the heart?

hardens artery walls, increase BP lead to heart failure
