Answer: Decrease

It will decrees because required volume of blood will not be   emptied into the pulmonary circulation  to reach the lung for oxygenation. Rather blood flows back into the  Right  atrium ,(regurgitation,) through the these valves   during ventricular contraction ( systole)of the Right Ventricle instead to the pulmonary circulation which  reduces blood flow leading  to volume overload  in  the heart. Eventually this  affects systemic circulation,

Describe the structure and the function of the stomach. Be sure to include cells and tissues relating to this organ.
Vikentia [17]

Connective tissues support the tissues of the mucosa and connect it to the muscularis layer.

The blood supply of the submucosa provides nutrients to the wall of the stomach. Nervous tissue in the submucosa monitors the contents of the stomach and controls smooth muscle contraction and secretion of digestive substances.

<h3>What is the function of the stomach?</h3>

The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach.

The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

Thus, this could be the answer.

Answer:

  • Blood sugar regulation in a diabetic patient is done by
  1. Injecting prescribed quantity of hormone insulin after definite time intervals.
  2. Consuming prescribed amount of sugars.
  3. Injecting glucagon to maintain blood sugar level if alpha cells of the pancreas are also non-functional.

Explanation:

  • The concentration of sugar in the blood is regulated by the hormone, insulin, produced in the pancreatic beta cells in normal person and injected from outside in a diabetic person.
  • When the concentration of glucose in the blood is high, the insulin signals the hepatocytes to express their glucose transporters to take up the excess glucose from blood and convert them to glycogen.
  • When concentration of sugar in the blood is low, another hormone called glucagon, released from the alpha cells of the pancreas, signals the liver to carry out glycogenolysis (breakdown of glycogen to glucose) and release the glucose into the blood. This would maintain the glucose level in the blood.
  • In a diabetic patient, usually the beta cells of the pancreas are affected  but not the alpha cells, so the glycogenolysis can occur in the body spontaneously.
  • But excess injection of insulin should also be avoided as that can cause the blood sugar level to come down below normal.
