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.

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

• blood pressure decreases leading to more cardiovascular disease.

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

The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow? 

• A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow

• The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow

• The narrowing of blood vessels increases pressure and leads to a faster blood flow

• A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow
