What is a primary consequence of the narrowing of arteries?

The primary consequence of the narrowing of arteries is decreased blood flow. When arteries narrow, a condition often referred to as atherosclerosis can occur, leading to a reduced internal diameter of the blood vessels. This reduction in space limits the amount of blood that can pass through efficiently. As a result, tissues and organs may not receive adequate oxygen and nutrients, which can lead to various health issues including angina, heart attacks, or even strokes. Decreased blood flow can also cause increased workload on the heart as it struggles to pump blood through the narrowed vessels, illustrating why this outcome is significant in the context of cardiovascular health.
