Final answer:
Blood pressure is influenced by cardiac output, vessel elasticity, blood viscosity, systemic vascular resistance, and the condition of the aortic valve.
Step-by-step explanation:
Blood pressure in the cardiovascular system is determined by several factors, including cardiac output, blood vessel elasticity, blood viscosity, and systemic vascular resistance. The cardiac output is a product of heart rate and stroke volume and has a direct impact on systolic blood pressure. Vessel elasticity and blood viscosity influence both systolic and diastolic blood pressure. On the other hand, systemic vascular resistance, with factors such as vasoconstriction and vasodilation of arterioles, affects blood flow and pressure. The condition of the aortic valve can also affect pressure, especially if there is a valve disorder. Overall, the interplay between these elements regulates blood pressure to maintain efficient blood flow through the body.
