Question

trace the blood flow from the right kidney to the stomach

Answer 1

Given below is the pathway through which blood flows from the right kidney to the stomach

Right kidney - right renal vein - inferior vena cava - right atrium - right ventricle - pulmonary artery - lung - pulmonary vein - left atrium - left ventricle - aorta - celiac trunk(branch of abdomnal aorta) -Celiac trunk branchs into left gastric artery, splenic artery and common hepatic artery.

The splenic artery has 3 branches : pancreatic artery(supplies pancreas), left gastroepiploic artery(supplies stomach and greater omentum) and short gastric artery(supplies stomach)

Common hepatic artery has 3 branches : Proper hepatic artery(supplies the liver, stomach and gall bladder ), Right gastric artery(supplies stomach) and gastroduodenal artery (supplies stomach greater omentum, duodenum and pancreas.

There is no direct connection between the blood vessels draining the kidney and the blood vessels draining the stomach.Blood drained from the stomach and the kidneys get mixed up only in the inferior vena cava.

The blood from the right kidney is drained by the right renal vein which then drains into the inferior vena cava.

The venous blood from the stomach is drained by the left and right gastric veins ,left and right gastroepiploic veins and the short gastric veins.

The left and right gastric veins drain into the portal vein.The short gastric veins and the left gastroepiploic vein drain into the splenic vein.The right gastroepiploic vein drains into the superior mesenteric vein.

The superior mesenteric vein and the splenic vein unite to form the portal vein which drains into the liver sinusoids.

Venous blood from the liver is then drained by hepatic vein into the Inferior vena cava.

Finally the inferior vena cava drains into the right atrium.

The blood from the right atrium goes into the right ventricle.From the right ventricles blood is pumped through the pulmonary arteries.

Blood is then oxygenated and the oxygenated blood from the lungs reaches the left atrium through the pulmonary vein.

From the left ventricle blood is pumped through the aorta .Blood reaches stomach through the celiac trunk which is a branch of the abdominal aorta.

Blood then flows into the left ventricle and is pumped out through the aorta.

The celiac trunk which is a branch of the abdominal aorta is responsible for the arterial supply of the stomach.
