when the superior mesenteric vein and the splenic vein fuse, what is the name of the new vessel?

The superior mesenteric vein is a blood vessel that drains blood from the small intestine. It is located near the top of the stomach (jejunum and ileum). The superior mesenteric vein joins with the splenic vein behind the neck of the pancreas to produce the hepatic portal vein, which drains into the liver.

What does the superior mesenteric vein fuse with?

Located in the abdomen, the superior mesenteric vein (SMV) is a major venous channel that supplies blood to the heart. A minor tributary of the small intestine draining blood from the terminal ileum, caecum, and vermiform appendix forms within the mesentery of the small intestine, where it originates. It comes to a close by joining with the splenic vein and generating the portal vein (also known as the vena cava).

What fuses together to form the basilar artery?

The vertebral arteries arise as branches of the subclavian arteries and carry blood up the spinal column, toward the brain, until they reach the brain. The basilar artery, which provides blood to the back of the brain, is formed when these arteries join together.

What does the basilar artery branch into next?

The basilar artery comes to an end by dividing into the left and right posterior cerebral arteries at the base of the skull. The pontine arteries, anterior inferior cerebellar (AICA) and superior cerebellar arteries, as well as the terminal posterior cerebral arteries, are all important blood vessels in the brain.

What fuses with the splenic vein?

The IMV unites with the splenic vein, which then connects with the SMV to produce the portal vein, which is the largest vein in the body.

What is the superior mesenteric vein?

Located in the upper abdomen, the superior mesenteric vein (SMV) is a main venous tributary of this region. The superior mesenteric vein (SMV) is an artery that runs lateral to the superior mesenteric artery (SMA) and is responsible for draining the vast majority of the organs of the abdominal cavity. It was developed embryologically in connection with the vitelline vein.

What is the circle of Willis?

The Circle of Willis is a confluence of several arteries on the inferior (inferior) side of the brain located at the bottom of the brain. The internal carotid arteries divide into smaller arteries near the Circle of Willis, which give oxygenated blood to more than 80 percent of the brain.

What is pontine artery?

In the brain, the pontine arteries are a group of tiny arteries that branch off at right angles from each side of the basilar artery and feed blood to the pons and neighboring areas of the cerebral cortex. In addition to the paramedian arteries, the short circumferential arteries and the long circumferential arteries are included in the pontine arteries.

What forms basilar artery?

The basilar artery is a midline structure generated by the confluence of the vertebral arteries, which is located in the middle of the spine. Following this, the basilar artery divides into two branches that become the right and left posterior cerebral arteries, respectively. The basilar artery divides into multiple branches as it travels through the body.

Which vessel S originates between the superior and inferior mesenteric arteries?

Located between the superior and inferior mesenteric arterial systems, the marginal artery of Drummond is a collateral pathway that connects the two systems. The descending branch of the ileocolic artery, which is the most proximal branch of the SMA, serves as the genesis of the anastomotic network throughout the body.

Which veins lead directly back to superior and inferior vena cava?

The superior vena cava is produced by the brachiocephalic veins on the left and right sides of the body, which carry blood from the upper limbs, head, and neck. The inferior vena cava is a blood vessel that transfers blood from the belly and lower extremities to the heart. It is directly into the inferior vena cava that the hepatic veins of the liver and the renal veins of the kidney empty their contents.

Which vein brings blood from the head to the superior vena cava?

The Venae Cavae have a specific function. Upper chest veins link together to produce the superior vena cava, which is found in the upper chest area and is formed by the union of the brachiocephalic and aortic veins. These veins are responsible for removing blood from the upper body areas such as the head, neck, and chest.

Where is the superior mesenteric artery?

The superior mesenteric artery is one of the major arteries that provide blood to the abdominal organs. It connects the abdominal region of the aorta with the third segment of the small intestine, the ileum, on the other side of the body. In medicine, the term mesentery refers to a fold of tissue that attaches the small intestine to the abdominal wall and serves as an anchor for the bowel.

Where is the superior cerebellar artery?

The superior cerebellar artery emerges from the basilar artery at the conclusion of its course. It travels in a lateral direction around the brainstem. The posterior cerebral artery is right below the oculomotor nerve, which is what differentiates this artery from the anterior cerebral artery. Afterwards, it makes its way around the cerebral peduncle, where it comes near to the trochlear nerve.

Which two of the following arteries does blood from the brachiocephalic artery flow into next?

This is a blood vessel that begins from the aortic arch and travels to the brain and spinal cord. It is responsible for supplying blood flow to the right carotid artery and the right subclavian artery, among other things.
