inferior vena cava
What does the inferior venacava do
The blood flows into the right atrium from either the Superior vena cava or the inferior vena cava it then passes through the bicuspid valves into the right ventricle. The valves in the heart are all one way valves, so blood cannot flow through the valve in the opposite way. Once in the right ventricle it will pass through another valve into the pulmonary trunk into the pulmonary artery (right or left) and then to the lung where it will be oxygenated.
it houses the superior and inferior colliculi; the superior colliculi is related to vision while the inferior colliculi is related to sound.
The ears are what and what to the shoulders and what to the nose.Yes, the ears are superior to the shoulders and posterior and lateral to the nose.The ears are superior to the shoulders and posterior of the nose.
Superior and inferior are terms to tell where a part of the body is in relation to another part. to simplify it thing of it this way. Superior is above, inferior is below. So the umbilicus is inferior to the pectoralis major is like saying the unblicus is below the pectoralic major. The same goes for superior. Since almost ever part of the body has something above and below it, generally every body part can be either inferior or superior.
Inferior mesenteric
Celiac, superior and inferior mesenteric arteries
AnswerThe portal confluence is the area where the superior mesenteric vein and the splenic vein meet. They run posterior to the pancreas and form the portal vein.
There are two mesenteric arteries in the human the superior and inferior. Both leave the descending aorta directly nad supply the GI tract. These arteries provide the definition of the the boundaries of the foregut, midgut and hindgut. The superior supplies the midgut and the inferior supplies the hindgut.
Yes. The splanchnic circulation is very rich in terms of blood supply and vasculature. This allows for rapid absorption of essential nutrients.
The Inferior Mesenteric Vein (iMV) drains into the splenic vein. The splenic vein ultimately "meets up" with the Superior Mesenteric Vein (SMV) to form the Hepatic Portal Vein (HPV)
inferior vena cava
The hepatic portal vein is created by the anastamoses between the superior mesenteric vein and spleinc vein. It is arguable that the inferior mesenteric vein joins at this same anastomoses but generally it actually joins the splenic vein which then meats the sup. mesenteric vein as stated above. The veins that drain into the portal vein (ie above the ansastmoses between the splenic and sup. mesenteric) are the cystic vein, the right gastric vein and the posterior-superior part of the pancreaticoduodenal vein.
Phrenic arteries
Colic arteries supply blood to colon.Human colon has different portions (ascending colon, transverse colon, descending colon and sigmoid colon).Right colic artery supplies blood to ascending colon.Middle colic artery supplies blood to tranverse colon.Left colic artery supplies blood to the descending colon.Sigmoid arteries (two or three) supplies blood to sigmoid colon.The right colic and middle colic arteries are branches of superior mesentric artery.The left coliac artery and sigmoid arteries are branches of inferior esentric artery.
The superior mesenteric
The two veins that form hepatic portal vein are the splenic vein and the superior mesenteric vein. These veins usually receive blood from the inferior mesenteric, gastric, and cystic veins.
