Arteriosclerosis is a disease which clogs arteries in the human body. In arteriosclerosis, artery walls become thick. Fatty deposits build up on inner walls of arteries. This condition reduces the ability of arteries to perform their function. The diagram above shows a comparison between a healthy artery and one with arteriosclerosis. Which of the following explains how Atherosclerosis affects the Body?

• Decreases the circulation of Blood to tissues

• Assembles Amino Acids into Proteins

• Replaces damaged Cells with new Cells

• Breaks down Food particles into Molecules

Which of the following factors would most directly affect blood flow through the circulatory system?

• blood pressure

• blood sugar

• respiratory rate

• outside temperature

Why would you become dizzy if you were to lose a lot blood?

• Your blood volume increased and therefore your blood pressure increased, making you feel dizzy.

• Your blood volume decreased and therefore your blood pressure decreased, making you feel dizzy.

• Your blood volume stayed the same but your blood pressure increased, making you feel dizzy.

• Your blood viscosity decreased and your blood pressure increased, making you feel dizzy.

Which of the following best describes the connection between cardiovascular disease and age?

• As people age, their blood vessels become more elastic leading to less cardiovascular disease.

• As people age, the heart becomes more efficient with each pump, increasing cardiac output.

• As people age, blood pressure decreases leading to more cardiovascular disease.

• As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.

If you were to lose a large amount of blood (blood volume), your blood pressure

• drop.

• rise.

• stay the same.
