PhysiologyThe intestinal phase of gastric acid secretion is primarily responsible for the inhibition of acid secretion, helping to regulate the digestive process after food enters the intestine.

PhysiologyGastrin is released from G cells in the antral mucosa of the stomach in response to the presence of food. It stimulates the parietal cells of the stomach to secrete hydrochloric acid and intrinsic factor, contributing to the gastric phase of acid secretion.

PhysiologyThe primary function of the juxtaglomerular apparatus (JGA) is the secretion of renin, which regulates blood volume and blood pressure.
399655
PhysiologyThe threshold for phosphate excretion is when the plasma phosphate concentration reaches approximately 0.50 mM, causing some to be filtered into the urine.

PhysiologyAnswer: 2) Decreases peripheral vascular resistanceExplanation: Thyroid hormones cause vasodilatation in several vascular beds, which decreases peripheral vascular resistance. This, along with increased cardiac output, leads to an overall increase in systolic blood pressure despite the diastolic BP possibly decreasing due to reduced resistance.
