Artery, splenic

Artery, splenic

A large artery within the abdomen that arises from an arterial vessel called the celiac trunk, which emerges from the aorta. The splenic artery supplies blood not only to the spleen, but also to the esophagus, stomach, duodenum, liver, and pancreas.

RELATED TERMS
--------------------------------------

Artery
A blood vessel that carries blood from the heart to the body.

Abdomen
The area between the chest and the hips. Contains the stomach, small intestine, large intestine, liver, gallbladder, pancreas, and spleen.

Celiac
Having to do with the abdomen.

Aorta
The largest artery in the body and the primary blood vessel leading from the heart to the body.

Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.

Spleen
The organ that cleans blood and makes white blood cells.

Esophagus
The organ that connects the mouth to the stomach. Also called gullet.

Stomach
The organ between the esophagus and the small intestine. The stomach is where digestion of protein begins.

Duodenum
The first part of the small intestine.

Liver
The largest organ in the body. The liver carries out many important functions, such as making bile, changing food into energy, and cleaning alcohol and poisons from the blood.

Pancreas
A large, elongated gland located behind the lower portion of the stomach that secretes the hormones insulin and glucagon into the blood. These hormones are essential in regulating blood sugar levels. The pancreas also secretes enzymes into the small intestine that help with digestion and neutralize acid from the stomach.

Artemidorus
"Artemidorus of Daldis. Greek physician who wrote Oneirocritica, a work dedicated to the interpretation of dreams, in the middle of the second century C.E. Artemidorus gathered evidence during interviews with thousands of people about their dreams. While his work has often been dismissed as mere divination, the careful study of dreams by modern psychiatrists has brought them back into the realm of scientific observation. ""In later antiquity Artemidorus of Daldis was regarded as the greatest authority on dream-interpretation ..."" (Sigmund Freud, The Interpretation of Dreams)"

Artemisinin
An antimalarial agent extracted from the dry leaves of the Chinese herb Artemsisia annua (qinghaosu or sweet wormwood). This plant is grown each year starting from seed and only yields artemesinin under specific agricultural and climatological conditions. Wormwood is cultivated only in China, Vietnam and pilot projects in Tanzania and India. It takes eight months to mature.

Artemsisia annua
A Chinese herb (qinghaosu or sweet wormwood) from which is extracted the antimalarial agent artemisinin.

Arterial aneurysm
"An outpouching (aneurysm) of an artery. As opposed to a venous or cardiac aneurysm. An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture. The word ""aneurysm"" comes from the Greek ""aneurysma"" meaning ""a widening."""

Arterial blood gas
ABG. The sampling of the blood levels of oxygen and carbon dioxide within the arteries, as opposed to the levels of oxygen and carbon dioxide in venous blood. Typically, the acidity, or pH, of the blood is measured simultaneously in ABG sampling.

Arterial blood gas (ABG)
The sampling of the blood levels of oxygen and carbon dioxide within the arteries, as opposed to the levels of oxygen and carbon dioxide in venous blood. Typically the acidity, or pH, of the blood is measured simultaneously with the gas levels in ABG sampling.

Arterial Grafting
In patients who require coronary artery bypass graft surgery, it is sometimes desirable to use arteries from other parts of the body to provide the bypass grafts. This is known as arterial grafting. The alternative is to use vein grafts for coronary bypass surgery.

Arterial tension
The pressure of the blood within an artery, the arterial pressure. Also called the intra-arterial pressure.

Arteries
Blood vessels that carry blood away from the heart to the arms, legs, head, body and organs.

Arteries, coronary
The vessels that supply the heart muscle with blood rich in oxygen. They are called the coronary arteries because they encircle the heart in the manner of a crown.

Arteriogram

Arteriohepatic dysplasia
Also known as Alagille syndrome, this ia a genetic disorder characterized by jaundice in the newborn period, liver disease with cholestasis, peripheral pulmonic stenosis and unusual face. Children with Alagille syndrome usually present with jaundice (yellowing of the skin and whites of the eyes) in the newborn period. Cholestasis (stagnant flow of bile from the liver) then develops with puritis (itching), stools without the usual yellowing brown color, and enlargement of the liver and spleen. Peripheral pulmonic stenosis is a form of congenital heart disease (CHD). Other types of CHD also occur. The face has deep-set eyes, broad forehead, long nose with flat tip, prominence of the chin, and low-set or malformed ears. The outlook depends upon the degree of severity of the CHD and the liver disease (it can cause liver failure). The condition is an autosomal dominant trait meaning that the gene for it is on a non-sex chromosome (an autosome) and a single edition of the Alagille gene is sufficient to produce the disease.

Arteriole
A small branch of an artery (a vessel that carries blood high in oxygen away from the heart to the body) leading to a capillary. The oxygenated hemoglobin (oxyhemoglobin) makes the blood in arteries and arterioles look bright red.

Arteriosclerosis
Commonly called "hardening of the arteries;" a variety of conditions caused by fatty or calcium deposits in the artery walls causing them to thicken.

Arteriosclerosis ("hardening of the arteries")
The process whereby abnormal deposits of lipids, cholesterol and plaque build up, leading to narrowing or blockage in arteries taking blood to the hand, foot head or vital organs. Also called atherosclerosis.

Arteriosclerotic aneurysm
A localized widening (aneurysm) of a vessel that occurs because the vessel wall is weakened by arteriosclerosis. An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture.

Arteriosclerotic retinopathy
"Retinal disease caused by arteriosclerosis. In this condition, the arterioles (small arteries) in the retina become partially blocked because of thickening of their walls. Using an ophthalmoscope, a doctor can see the thickened arterioles and other indications of diminished blood supply to the retina. (The characteristic features include narrowed tortuous arterioles with a ""copper wire"" appearance, scattered small hemorrhages and sharp-edged deposits with no edema around them.) As a general rule, arteriosclerotic retinopathy does not damage vision, although it is a danger signal that the blood vessels in the body are arteriosclerotic and that steps are badly needed to prevent the progression of the disease process."

Arteriovenous
Of, relating to, or connecting both arteries and veins.

Arteriovenous malformation
Abnormal group of dilated blood vessels, most often occurring in the brain.

Arteritides
Inflammation of an artery.

Arteritis
Inflammation of blood vessels (arteries). Causes problems in the organs or tissues supplied by those arteries.

Arteritis, cranial
" A serious disease characterized by inflammation of the walls of the blood vessels (vasculitis). The vessels affected are the arteries (hence the name ""arteritis""). The age of affected patients is usually over 50 years of age. Cranial arteritis is also known as temporal arteritis and as giant cell arteritis. It can lead to blindness and/or stroke. The disease is detected by a biopsy of an artery. It is treated with high dose cortisone-related medications."

Arteritis, giant cell
A chronic vascular disease, most often involving the carotid artery system, that can lead to blindness and/or stroke, Giant cell arteritis (also called temporal arteritis) is detected by a biopsy of an artery, and is treated with high dose cortisone.
