a man has just learned that he has a blockage in one of his arteries. which of the statements is true regarding this blockage? p
Alik [6]

This blockage will likely increase the resistance to flow in his circulatory system, and as a result will decrease the rate of blood flow.

Blood vessels in the circulatory system transport blood away from and towards the heart. Arteries transport blood away from the heart, while veins transport blood back to the heart. The circulatory system transports oxygen, nutrients, and hormones to cells while also removing waste products such as carbon dioxide.

Vascular disease (vasculopathy) affects the blood vessels that transport oxygen and nutrients throughout your body and remove waste. Plaque (made of fat and cholesterol) slows or blocks blood flow inside your arteries or veins, causing common vascular problems. When there is too much cholesterol in the blood, the cholesterol and other substances can combine to form deposits (plaques) on the artery walls. Plaques can cause an artery to narrow or become blocked.

Blacks "live within two concentric circles of segregation" means
mr_godi [17]
<span>King stated this, he believed that black people were located at the bottom of the economic ladder. Their two circles of segregation were one that kept them prisoner based on their skin color while the other held them prisoner in poverty and deprivation. The average black person struggles to escape his circumstances but is hindered by these factors. He receives no normal education and no normal social or economic opportunities. When he attempts to try to better himself, he is told to lift himself up on his own by bis bootstraps, advice that is senseless considering he is often barefoot.</span>
