The correct option is D GIP - secretion of glucagon
The ingested food especially glucose, when it reaches the small intestine, triggers the release of hormone called Gastric inhibitory Peptide or GIP. GIP stimulates pancreas to secrete insulin. Insulin mediates the absorption of glucose and other nutrients.
The juxtaglomerular cells of kidney produce a peptide hormone called erythropoietin which stimulates erythropoiesis (formation of RBC).
A fall in glomerular glomerular blood pressure/GFR in kidneys can trigger the JG cells to release renin to regulate GFR.
A increase in blood pressure triggers the release of ANF. ANF acts on the blood vessels leading to vasodilation and decrease in blood pressure.
