What does SMV mean in PHYSIOLOGY
An abbreviation is an acronym consisting of the first letters of each word in a phrase or title. Abbreviations are often used to make lengthy terms more concise and easier to remember. The Superior Mesenteric Vein (SMV) is an important vein in the human body located near the liver, intestines, and stomach. It receives blood from the small intestine, appendix, ascending colon, and descending colon before it joins with the splenic vein to form the portal vein. The SMV plays an essential role in many body functions as it helps carry fresh oxygenated blood throughout the abdomen and digestive organs.

Function of SMV
The primary function of SMV is to carry oxygen-rich blood from various parts of the gastrointestinal tract back into circulation. As such, oxygenation of vital organs such as the pancreas, spleen, stomach and liver can be maintained by this vessel's flow of nutrients and oxygenated blood pressure. Additionally, it also helps maintain proper amounts of fluids in these organs by helping regulate fluid levels within them as well as carrying out waste products away from these organs to be disposed through urine or bile production respectively.
Importance
The importance of SMV can not be overemphasized because it plays a critical role in optimal functioning of various organs in our digestive system like pancreas, spleen etc . If there is any injury or obstruction in its functioning it can disturb optimal functioning leading to a variety of medical conditions ranging from diarrhea to even cancer containing cell's spreading into other parts of body leading to life threatening situations.
Essential Questions and Answers on Superior Mesenteric Vein in "MEDICAL»PHYSIOLOGY"
What is a superior mesenteric vein?
The superior mesenteric vein (SMV) is a large vein that runs along the small intestine in the abdomen. It drains blood from the small intestine and directs it to the liver. It is part of the systemic venous system and connects with other veins like those from the pancreas, ascending colon, and transverse colon.
What organs does the superior mesenteric vein supply?
The superior mesenteric vein supplies oxygen-rich blood to many organs in the abdomen, including the small intestine, pancreas, ascending colon, transverse colon, jejunum, and ileum.
Where is the superior mesenteric vein located?
The superior mesenteric vein is located in between two arteries – one artery leading from the aorta (the largest artery in the body) to the duodenum (first part of small intestine), and another artery that branches from that main artery to reach all parts of the digestive tract except for rectum.
How does blood flow through Superior Mesenteric Vein?
Blood flows from intestinal vessels towards SMV which then carries it towards portal circulation which in turn joins inferior vena cava (IVC). After IVC supoerior mesenteric veins delivers it to liver for further processing.
Is there anything different between hepatic portal vein & SMV?
Yes, there are differences between hepatic portal vein and SMV. The HBP conducts blood coming from capillaries into its interior whereas SMV receives outflow of blood from many intestinal vessels but concentrate them before transferring them into HBP.
What happens if Superior Mesenteric Vein becomes blocked or damaged?
If an obstruction or damage occurs within SMV it can lead to various conditions such as portal hypertension and cirrhosis. This may cause excessive fluid accumulation which can result in abdominal swelling or enlargement of veins around rectal area known as ascites. Furthermore, presence of clots within vessel can even be life threatening if not treated properly on time.
Does Superior Mesentery Vien have any connection with lymphatic system?
No, SMV has nothing to do with lymphatic system as unlike lymphatics this vessel carries only oxygenated blood away from intestinal vessels towards liver via HBP for further processing before entering inferior vena cava for delivery back systemic circulation for nutrients exchange inside body tissues and cells.
Final Words:
In conclusion, Superior Mesenteric Vein (SMV) is an important part of our circulatory system that carries oxygen-rich blood from many different parts throughout our bodies mainly towards our digestive systems so that vital organs such as pancreas, spleen etc., receive proper nutrition and oxygen circulation. Its importance cannot be understated since its blockade or dysfunction can lead to very serious health issues if left untreated for longer period times.
