What happens to the arterial walls during systolic pressure?

  1. They relax completely

  2. They experience the greatest amount of pressure

  3. They maintain a constant pressure

  4. They constrict slightly

The correct answer is: They experience the greatest amount of pressure

During systolic pressure, the heart contracts and pumps blood into the arteries, leading to an increase in pressure within the arterial walls. This phase of the cardiac cycle is characterized by the maximum force exerted by the blood against the artery walls, resulting in the greatest amount of pressure. When the heart beats, blood is expelled into the arteries, causing them to expand due to the increased volume of blood. This expansion represents the peak pressure that occurs with each heartbeat, which is what systolic pressure measures. Consequently, it reflects the health and function of the cardiovascular system, as well as the state of the arterial walls when subjected to this heightened pressure. While some options suggest other physiological responses, they do not accurately characterize the dynamics of arterial response during systole, making the understanding of systolic pressure critical for assessing cardiovascular health and function.
