Question

What vein drains the lesser curvature of the stomach, and empties directly into the hepatic portal vein?

Answer 1

Hint: The veins of the lower limb drain and return deoxygenated blood to the heart. They are classified into two categories: deep and superficial: Deep veins run alongside the major arteries beneath the deep fascia of the lower limb.

Complete answer:
The portal vein, also known as the hepatic portal vein (HPV), is a blood vessel that transports blood from the gastrointestinal tract to the liver via the gallbladder, pancreas, and spleen. The nutrients and toxins extracted from the digested contents are found in this blood. The portal vein carries about 75% of total liver blood flow, with the remainder coming from the hepatic artery itself. The hepatic veins carry blood from the liver to the heart.
Along the lesser and greater curvatures, the gastric veins are in a similar position to the arteries. These veins drain into the portal system either directly or indirectly. The left gastric vein and Right gastric vein are the lesser curvature of the stomach and empty directly into the hepatic portal vein.
The diagram below depicts the various parts of the stomach. Here is the stomach curvature that is less pronounced:

The left and right gastric veins drain the lesser curvature of the stomach. Look at the diagram below.

Both the left and right gastric veins empty into the portal vein of the liver.

Note:
The left gastric vein collects deoxygenated blood from the stomach's lesser curvature. It also serves as a conduit between the portal vein and the lower esophageal systemic venous system. The right gastric vein carries deoxygenated blood away from the stomach's lesser curvature.
