What enzyme is activated by HCI in the gastric phase?

Polyethylene Glycol:This osmotic laxative is prescribed for patients experiencing acute constipation to soften stool and facilitate evacuation. It increases the water content within the colon through osmotic pressure. It is used for short-term symptomatic relief.

Linaclotide:This guanylate cyclase-C agonist is indicated for patients with IBS-C to increase intestinal fluid secretion and motility. It also reduces visceral pain by decreasing the activity of pain-sensing nerves. It addresses both constipation and abdominal discomfort.

Imodium:Loperamide is an opioid-receptor agonist used for patients with IBS-D to slow intestinal transit. By increasing the residence time of chyme, it allows for greater water resorption and reduced stool frequency. It treats the hypermotility associated with diarrhea.

A. Aorta:This is the primary systemic artery that carries oxygenated blood away from the heart. It does not receive venous drainage from any organ. Blood flow in the aorta is always moving toward the peripheral tissues.

B. Superior vena cava:This large vein drains the head, neck, and upper extremities into the right atrium. It is located superior to the diaphragm and does not receive blood from the liver. Hepatic drainage occurs via the inferior vessel.

C. Hepatic artery:This vessel is a branch of the celiac trunk that delivers oxygenated blood to the liver parenchyma. It is an inflow vessel rather than an outflow vessel. It provides the liver with its nutrient and oxygen supply.

D. Inferior vena cava:This is the terminal vessel for all venous drainage below the diaphragm. The hepatic veins emerge from the posterior surface of the liver to join this vessel directly. It then returns the blood to the heart.
