Eustation tubes which drain into the back of the esophagus.
Dural venous sinuses are found between the periosteal and meningeal layers of the dura mater, which is the outermost layer of the meninges surrounding the brain. These sinuses drain blood and cerebrospinal fluid from the brain and ultimately connect to the internal jugular vein.
The dural sinuses are blood-filled channels located between the layers of the dura mater, the outermost membrane surrounding the brain. They collect blood from the brain and drain it back into the systemic circulation through the internal jugular vein. The sinuses contain venous blood, cerebrospinal fluid, and arachnoid granulations.
The deoxygenated blood leaves the brain via the dural sinuses. These are large veinous structures located in the dura mater that connect with the internal jugular vein.
The superior sagittal sinus is a vein located in the dura mater that runs parallel to the longitudinal fissure of the brain. It collects blood and cerebrospinal fluid from the superior aspects of the brain and drains into the internal jugular vein.
internal jugular!
Yes. Fibrous - Serous dura matter - endothelium - dura venous sinus - endothelium - serous - arachnoid matter ....so then the answer is really No, it is between the 2 layers of the dura.
The Internal Jugular drains the brain via the collection of blood from the superior sagittal sinus, inferior sagittal sinus, straight sinus, right transverse sinus, sigmoid sinus, and cavernous sinus (to name a few).....The other jugular....The External Jugular drains the occipital, facial (also drained by internal jugular), maxillary, and temporal veins.
Right Lymphatic
Azygous vein
The hepatic portal vein is formed by the union of (a) splenic vein, which drains the spleen, pancreas, greater curvature of stomach and (b) superior mesenteric, which drains the small intestine and ascending colon. The gastric vein, which drains the lesser curvature of the stomach, empties directly into the hepatic portal vein.The hepatic portal vein is formed by the union of (a) the splenic vein, which drains the spleen, part of the pancreas, and the stomach & (b) superior mesentic vein, which drains the small intestine and transverse colon. The left gastric vein, which drains the lesser curve of the stomach, empties directly into the hepatic portal vein.
The external iliac vein drains into the common iliac vein as it enters the pelvis.
Hepatic vein drains the liver, carrying oxygen-depleted blood back to the heart.
