What number in Arabic numerals is Roman numeral MCMXLIV?
The body is composed of systems that have evolved and diversified in order to maintain the
natural functions and processes they regulate. One such system that has these regulators is the
body's cardiovascular system. The body's pump, which regulates the flow of vitally needed
oxygen to all cells of the body, as well as the discard of carbon dioxide and other waste products,
is the heart.
Because blood pressure varies at different points within the body, differing components are
needed to keep the body's blood pressure regulated. Three of the basic components are
baroreceptors, chemoreceptors, and kidneys.
Baroreceptors are stretch receptors composed of fine branching nerve endings and are contained
along the walls of the arteries near the heart and in other areas of the body as well. Impulses are
related to this stretching along the arterial walls, which causes these baroreceptors to send out
even more impulses to the heart, arteries, and veins, causing the blood pressure to go either up or
down.
Chemoreceptors are located along the walls of the arteries and monitor changes in oxygen level,
carbon dioxide, and pH. Just think! A fall in oxygen causes receptors to send impulses to raise
blood pressure.

The kidneys play a role in regulating blood pressure by absorbing salts and water and removing
wastes. Hormones secreted by the adrenal cortex cause the kidney to keep or let go of any salt
and water. This has an influence on blood volume and consequently on blood pressure.
What is the main idea of the passage?
A. Blood pressure can be treated only by monitoring baroreceptors.
B. Blood pressure can be treated only by monitoring chemoreceptors.
C. Blood pressure can be treated only by monitoring the kidneys.
D. Blood pressure can be regulated through baroreceptors, chemoreceptors, and the kidneys.
