Two images of blood flow are shown - HSC - SSCE Personal Development and Physical Education - Question 12 - 2018 - Paper 1

To determine the condition represented by Image B, we need to understand the differences between the listed options:

1. Arteriosclerosis - This condition is characterized by the thickening and hardening of the arterial walls, which can lead to a loss of elasticity. It is often associated with aging and can also be influenced by factors such as high blood pressure.

2. Atherosclerosis - This is a specific type of arteriosclerosis involving the buildup of fats, cholesterol, and other substances in and on the artery walls (plaque). This condition can impede blood flow and result in serious heart complications.

3. Low blood pressure - This refers to a condition where the blood pressure in your arteries is abnormally low. It generally doesn't show an image of blood flow alterations related to arterial thickening or blockage.

4. Low cholesterol levels - This condition usually does not pose a risk as low cholesterol is generally considered healthier; it does not inherently cause a visible abnormality in blood flow.

Given the context of blood flow in Image A and the recognition of common cardiovascular issues, if Image B shows abnormal blood flow likely due to blockage or narrowing of arteries, it is most reasonable to conclude:

Answer: B. Atherosclerosis.
