Regulation of Arterial Pressure

These flashcards cover key concepts related to the regulation of arterial pressure, cardiovascular system mechanisms, and the physiological responses involved.

Arterial Pressure

The driving force that causes blood circulation and is closely monitored for stability. Caused by the heart.

Total Peripheral Resistance (TPR)

The total resistance to blood flow throughout the body, which is regulated to maintain arterial pressure.

Autonomic Nervous System (ANS)

The part of the nervous system that regulates involuntary actions, such as heart rate and vascular resistance, involved in short-term regulation of arterial pressure.

Mean Arterial Pressure (MAP)

The average pressure in a person's arteries during one cardiac cycle, typically around 100 mm Hg.

CO x TPR

Arterial Baroreceptor Reflex

A rapid response mechanism that stabilizes blood pressure by adjusting heart rate and blood vessel constriction when pressure changes. keep BP stable

Blood Volume Adjustments

Changes in blood volume that influence cardiac output and long-term regulation of arterial pressure.

Local Vascular Resistance

The resistance of blood vessels within a specific area of the body, which can be adjusted to meet local metabolic needs.

Regulation of Blood Flow

The process by which blood circulation to tissues is adjusted according to their metabolic requirements.

Homeostasis in Blood Pressure

The maintenance of stable arterial pressure within the body through various physiological mechanisms.
