Abstract:
Renin is secreted episodically in the absence of overt stimulation in the pentobarital-anesthetized, saline-loaded cat. Ninety min postlaparotomy, arterial and renal venous plasma renin concentrations (PRC) were determined at 15-min intervals for a 2 hr period. The pattern of renin secretion consisted of significant secretory peaks and periods in which little or no renin was secreted. In only a few instances could renin secretion be attributed to a preceding arterial blood pressure drop. The secretory episodes were also dissociated from flow.

Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
