25.
When an individual has high cholesterol, certain substances, such as calcium and fats, form plaque in arteries. How is this plaque, known as arterial plaque, most likely to affect blood flow?
a)
Arterial plaque clogs the arteries, limiting or stopping blood flow.
b)
Arterial plaque changes the direction of blood flow, which forces oxygenated blood to the heart.
c)
Arterial plaque changes the size of blood cells, which prevents blood from flowing in the arteries.
d)
Arterial plaque clears the arteries, increasing blood flow.

A doctor prescribes a blood thinner to a patient with high blood pressure. What impact will this medication have on blood flow and viscosity?
b)
The blood flow will decrease and the viscosity will increase.
c)
The blood flow will increase and the viscosity will decrease

The blood flow will increase and the viscosity will increase.
31.
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)
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
b)
A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow.
c)
The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.
d)
The narrowing of blood vessels increases pressure and leads to a faster blood flow.
