What are two factors that affect blood pressure?
Two factors that affect blood pressure are:1. Cardiac Output: This refers to the amount of blood pumped out by the heart per minute. The higher the cardiac output, the higher the blood pressure. Factors such as heart rate, stroke volume (the amount of blood pumped out with each heartbeat), and contractility (the force of the heart's contractions) all influence cardiac output.
2. Systemic Vascular Resistance: This represents the resistance to blood flow in the blood vessels. The narrower the blood vessels, the higher the resistance and the higher the blood pressure. Factors like the tone of the blood vessel walls (affected by hormones, nerve activity, and other substances) and the blood volume can impact systemic vascular resistance.
