The part of the circulatory system that is especially vulnerable to blockages is arteries.
The part of the circulatory system that is especially vulnerable to blockages is the arteries.
The arteries are responsible for carrying oxygen-rich blood from the heart to the rest of the body. They have a thick and elastic muscular wall to withstand the pressure generated by the heart during pumping. However, over time, plaque can build up in the arteries, causing them to become narrower and restrict blood flow. This process is known as atherosclerosis.
There are a few ways to determine that the answer is arteries. One way is to have prior knowledge of the circulatory system and the different components involved. Another way is to reason through the options provided. Capillaries are tiny blood vessels that connect arteries and veins, so they are not the main site of blockages. The heart is the muscular organ responsible for pumping blood, but it is not typically the site of blockages. Veins carry blood back to the heart and have thinner walls compared to arteries, making them less prone to blockages. Therefore, the most logical option is arteries.
