Where does blood from the stomach go?

Where does blood from the stomach go?

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 is associated with the abdominal viscera?

The solid abdominal viscera (singular: viscus) is a collective term for those internal organs of the upper abdomen that are primarily solid in nature, namely the liver, pancreas, spleen, adrenals, and kidneys.

How does blood flow through the abdomen?

Venous drainage of the abdomen is by the inferior vena cava and its tributaries. The blood from the portal vein passes through the liver and finally drains into the inferior vena cava. The inferior vena cava forms at the level of the fifth lumbar vertebra by the joining of left with the right common iliac veins.

Which large arteries supply the abdominal viscera?

The blood supply to all the organs in the abdomen that we’ve seen so far, the GI tract, the liver, pancreas and spleen, comes from three midline branches of the abdominal aorta. These are the celiac, the superior mesenteric and the inferior mesenteric arteries.

Which blood vessels drain blood from the stomach?

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. These three tributaries drain into the portal vein, which supplies the liver whose venous effluent is delivered back to the heart [2,4,5].

What is the role of the blood in the stomach?

Gastric blood flow plays an important role in sustaining the normal physiologic functions of the stomach and it helps to protect the gastric mucosa against ulcer formation. Intrinsic regulatory mechanisms ensure that blood flow is adjusted to meet the energy-demanding processes of gastric secretion and motility.

What conditions of the abdominal viscera produce pain in the abdominal region?

Visceral pain

  • injuries to internal organs, such as the gallbladder, intestines, bladder, or kidneys.
  • damage to the core muscles or abdominal wall.
  • spasms in the core muscles.
  • acid indigestion.
  • other digestive problems such as constipation.
  • infections in the digestive and renal systems.

What structures are classified viscera?

Visceral: Referring to the viscera, the internal organs of the body, specifically those within the chest (as the heart or lungs) or abdomen (as the liver, pancreas or intestines).

What supplies blood to the abdominal wall?

Blood Supply and Lymphatics The major arteries of the anterolateral abdominal wall are the superior epigastric, inferior epigastric, musculophrenic, subcostal, and posterior intercostal arteries, deep circumflex iliac artery, superficial circumflex iliac artery, and superficial epigastric artery.

What is the direction of blood flow in the abdominal aorta?

This hole in the diaphragm that allows the passage of the great vessels at the vertebral level of T12. The abdominal aorta travels down the posterior wall of the abdomen, anterior to the vertebral column, following the curvature of the lumbar vertebrae.

What arteries supply the abdomen?

The stomach is supplied by a rich system of arteries derived from the celiac trunk, the first major visceral branch of the abdominal aorta. The lesser curvature of the stomach is supplied by the left and right gastric artery, which are branches of the celiac trunk and the common hepatic artery respectively.

What are the visceral arteries?

The visceral arteries supply blood to the intestines, spleen, and liver. Visceral artery conditions are acute or chronic conditions that reduce blood flow in these arteries. As with other blood vessels, the visceral arteries can either become blocked (usually by plaque) or dilated (by aneurysms).

Where are the venous blood vessels located in the abdomen?

The venous blood is conveyed through the superior, middle and inferior rectal veins. As you know, the peritoneum consists of the parietal and visceral peritoneum. The parietal peritoneum is supplied by the vessels of the abdominal wall. The visceral peritoneum is supplied by its associated viscera.

Where does the blood come from in the pelvis?

As the abdomen and pelvis contain the majority of internal organs, these regions need to be supplied by an extensive network of arteries and veins. That being said, all arterial blood delivered to this region comes via branches of the abdominal aorta, and all venous blood eventually finds its way back to inferior vena cava (IVC).

What kind of blood supply does the pelvic viscera have?

Systemic Circuit. Lumbar arteries provide blood for the muscles and spinal cord. Branches of the external iliac artery provide the blood supply for the lower extremity. The internal iliac artery supplies the pelvic viscera.

Where does the blood supply the stomach go?

After giving the duodenal artery, the common hepatic artery continues as the hepatic artery proper, and on its way to the liver, it gives the right gastric artery. This artery runs along the lesser curvature of the stomach, supplying its walls and anastomosing with the left gastric artery.
