The splenic vein drains the stomach, the superior mesenteric vein drains the upper small intestine, while the inferior mesenteric vein drains the distal portions of the colon.

What are the 4 main veins draining the stomach?

Conventionally the following veins drain into the splenic vein—short gastric, left gastroepiploic, pancreatic, and inferior mesenteric veins. The short gastric veins include four or five veins, which drain the fundus and part of the greater gastric curvature.

What vein drains the small and large intestine?

The superior mesenteric vein (SMV) is a large blood vessel in the abdomen. Its function is to drain blood from the small intestine as well as the first sections of the large intestine and other digestive organs.

Where are the veins that drain the digestive and gut organs?

The veins that drain the gastrointestinal organs parallel the major arteries that supply the foregut, midgut, and hindgut, including the celiac, superior mesenteric, and the inferior mesenteric arteries respectively. These veins eventually convene at the portal vein, forming a single venous inflow tract into the liver.

What is the venous drainage of the small intestine?

The mesenteric veins parallel their corresponding arteries. The SMV drains the small intestine, cecum, and ascending and transverse colon via the jejunal, ileal, ileocolic, right colic, and middle colic veins.

What do veins on stomach mean?

The appearance of swollen veins around your belly button is a symptom of circulatory issues. The root cause of caput medusae is portal hypertension, which is an increase in pressure in the portal vein. That’s the vein that moves blood from your digestive tract to your liver.

Which organ filters blood coming from the digestive system?

The liver’s main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines.

What does portal vein drain into?

The portal vein (PV) is the main vessel of the PVS, resulting from the confluence of the splenic and superior mesenteric veins, and drains directly into the liver, contributing to approximately 75% of its blood flow [1].

Which veins drain into left renal vein?

Renal Veins

The left gonadal vein will drain into to left renal vein. The right gonadal vein drains directly into the inferior venal cava.

Where does blood from the small intestine drain into?

All the blood that flows from the intestines, stomach, and spleen is filtered through the liver. The blood flows into the liver through the hepatic portal vein. It filters through the liver in a system of smaller and smaller veins.

What drains into splenic vein?

The splenic vein drains the spleen, part of the pancreas, and part of the stomach.

What vein drains sigmoid colon?

The inferior mesenteric vein drains the mesenteric arcade of the hindgut (comprising of distal transverse, descending, and sigmoid colon).

What is venous drainage?

Venous drainage, anterior view. The systemic venous channels are further classified as superficial veins, deep veins, or venous sinuses. The superficial, or cutaneous, veins reside just beneath the surface of the skin. They channel blood from cutaneous tissues to deep veins via perforations in the deep fascia.

What is a portal venous system?

The portal venous system carries capillary blood from the esophagus, stomach, small and large intestine, pancreas, gallbladder, and spleen to the liver. The portal vein is formed by the confluence of the splenic vein and the superior mesenteric vein behind the neck of the pancreas.

What causes veins to burst in stomach?

Varices are dilated blood vessels in the esophagus or stomach caused by portal hypertension. They cause no symptoms unless they rupture and bleed, which can be life-threatening. Someone with symptoms of bleeding varices should seek treatment immediately.

Why are my veins so visible all of a sudden on my stomach?

In most cases, visible veins aren’t a cause for concern. Exercise, hot weather, sun exposure, and tight clothing can make your veins more noticeable. Aging, genetics, and being overweight may also increase their definition. Diseases that affect the vein are more serious.

What causes enlarged veins in the stomach?

Esophageal varices are abnormal, enlarged veins in the tube that connects the throat and stomach (esophagus). This condition occurs most often in people with serious liver diseases. Esophageal varices develop when normal blood flow to the liver is blocked by a clot or scar tissue in the liver.
