phase is associated with food stretching the stomach and activating myenteric and vagovagal reflexes, which in turn stimulate gastric secretions.

A. Urine output will decrease: Vasodilation of efferent arterioles lowers glomerular pressure, leading to a lower GFR and reduced urine output.
B. Glomerular filtration rate will decrease: A wider efferent arteriole reduces resistance, decreasing the pressure inside the glomerulus, hence lowering GFR.
C. Systemic blood pressure will decrease: Local vasodilation of the efferent arteriole does not significantly affect systemic blood pressure. Systemic pressure is influenced more by cardiac output and total peripheral resistance, not glomerular arteriole tone.
D. Net filtration pressure will decrease: Lower glomerular capillary pressure results in reduced net filtration pressure (NFP).

A. Stomach: The stomach mixes the food with gastric juices, converting the solid bolus into a semi-liquid substance called chyme.
B. Small intestine: The small intestine receives chyme but does not liquefy the bolus.
C. Mouth: The mouth forms the bolus through mastication and saliva, but it does not produce chyme.
D. Esophagus: The esophagus only transports the bolus via peristalsis and plays no role in liquefying it.
