Definitions:

Blood Pressure

The force of circulating blood on the walls of blood vessels, measured in millimeters of mercury (mmHg) and presented as two values: systolic and diastolic pressure.

Afferent Arterioles

Small blood vessels that carry blood toward the nephrons of the kidneys, regulating blood pressure and filtration rate.

Renin Secretion

Renin secretion involves the release of the enzyme renin from the kidneys, which plays a key role in the body's blood pressure regulation and electrolyte balance.

Autoregulation

Maintenance of a relatively constant blood flow through a tissue despite relatively large changes in blood pressure; maintenance of a relatively constant glomerular filtration rate despite relatively large changes in blood pressure.
