Explanation
The aorta originates from the left ventricle, courses towards the right, and is positioned superiorly to form the ascending aorta.

Rate this question:

4
3.

After the ascending aorta, it curves toward the __________(right or left) and ______________(anterior or posterior) to form the aortic arch.

Explanation
The ascending aorta is the first part of the aorta, which is the largest artery in the body. After the ascending aorta, it curves towards the left and posteriorly to form the aortic arch. This means that the aortic arch is located towards the left side and towards the back of the body.

Rate this question:

4
4.

After the aortic arch, the aorta descends inferiorly and is known as the _____________ aorta. It then gives rise to the _____________ aorta.

Explanation
After the aortic arch, the aorta continues its downward path and is referred to as the descending aorta. This portion of the aorta extends inferiorly through the thoracic cavity. From the descending aorta, branches arise to supply blood to the thoracic region, forming the thoracic aorta.

Rate this question:

4
5.

Once the aorta penetrates the diaphragm, it is termed the ________________ aorta.

Explanation
Once the aorta penetrates the diaphragm, it is termed the abdominal aorta. The aorta is the largest artery in the body and carries oxygenated blood from the heart to the rest of the body. As it passes through the diaphragm, which is a muscle that separates the chest and abdominal cavities, it becomes the abdominal aorta. This portion of the aorta supplies blood to the abdominal organs, including the stomach, liver, spleen, and intestines.

Rate this question:

4
6.

In the abdomen, the aorta runs _______________ (anterior or posterior) to the spine and slightly to the ____________ (right or left) of midline.

Explanation
In the abdomen, the aorta runs anterior to the spine and slightly to the left of midline. This means that it is positioned in front of the spine and towards the left side of the midline of the body.

Rate this question:

4
7.

The aorta begins _______________ (anterior or posterior) and becomes more _____________ (anterior or posterior) as it travels.

Explanation
The aorta begins at the posterior side and becomes more anterior as it travels. This means that the initial part of the aorta is located towards the back of the body, and as it progresses, it moves towards the front.

Rate this question:

4
8.

The first major branch off of the abdominal aorta is the _____________ axis.

Explanation
The celiac axis is the correct answer because it is the first major branch off of the abdominal aorta. The abdominal aorta is the main artery that supplies oxygenated blood to the abdominal organs, and the celiac axis specifically branches off from the anterior aspect of the abdominal aorta, just below the diaphragm. It then further divides into three smaller arteries that supply blood to the liver, stomach, spleen, and other abdominal organs.

Rate this question:

4
9.

The celiac axis arises at a _____________ angle from the _______________(anterior or posterior) aspect of the aorta.

Explanation
The celiac axis arises at a perpendicular angle from the anterior aspect of the aorta. This means that the celiac axis branches off from the aorta at a 90-degree angle, and it does so from the front or anterior side of the aorta. This anatomical information is important for understanding the blood supply to the abdominal organs, as the celiac axis is responsible for supplying blood to the stomach, liver, spleen, and other organs in that region.

Rate this question:

4
10.

The celiac axis is located _______________ to the pancreas.

Explanation
The celiac axis is located superior to the pancreas. This means that it is positioned above or higher than the pancreas.

Rate this question:

11.

The celiac axis is approximately ____(#) - ____(#) cm long.

Explanation
The celiac axis, also known as the celiac trunk, is a major branch of the abdominal aorta that supplies blood to the upper abdominal organs. It is approximately 2-3 cm long.

Rate this question:

4
12.

There are three branches of the celiac axis; the _______________ ______________ artery, the ____________ ______________ artery, and the ______________ artery.

Explanation
The celiac axis is a major branch of the abdominal aorta that supplies blood to the upper abdominal organs. It gives rise to three branches: the common hepatic artery, the left gastric artery, and the splenic artery. The common hepatic artery supplies blood to the liver, the left gastric artery supplies blood to the lesser curvature of the stomach, and the splenic artery supplies blood to the spleen.

Rate this question:

4
13.

The _____________ _____________ artery courses rightward from the celiac artery.

Explanation
The common hepatic artery is a branch that originates from the celiac artery and courses rightward. It supplies oxygenated blood to the liver and other structures in the abdominal region.

Rate this question:

4
14.

One branch of the common hepatic artery is the __________________ artery, which serves as a landmark for the anterolateral aspect of the head of the pancreas.

Explanation
The gastroduodenal artery is a branch of the common hepatic artery that serves as a landmark for the anterolateral aspect of the head of the pancreas. This means that it helps identify the location of the head of the pancreas by its presence.

Rate this question:

4
15.

After the GDA, the common hepatic artery becomes the _____________ ______________ artery.

Explanation
After the GDA (gastroduodenal artery), the common hepatic artery becomes the proper hepatic artery.

Rate this question:

4
16.

The proper hepatic artery enters the liver at the level of the ___________ ____________ with the portal vein.

Explanation
The proper hepatic artery enters the liver at the level of the porta hepatis, which is the central area of the liver where the portal vein and common bile duct also enter. The porta hepatis serves as the main entry point for blood vessels and bile ducts into the liver.

Rate this question:

4
17.

Once intrahepatic, the hepatic artery branches into the _____________, _______________, and ______________ hepatic arteries to supply the liver with blood.

Explanation
The hepatic artery, once it enters the liver, divides into three branches: the right hepatic artery, the middle hepatic artery, and the left hepatic artery. These arteries supply blood to different regions of the liver, ensuring that all parts receive an adequate blood supply.

Rate this question:

Rate this question:

4
19.

"Replaced right hepatic artery" occurs in 9-15% of the population, where the right hepatic artery arises from the ____________

Explanation
In 9-15% of the population, the right hepatic artery is replaced and instead arises from the superior mesenteric artery (SMA). This means that instead of the normal anatomical arrangement where the right hepatic artery originates from the common hepatic artery, it now branches off from the SMA. This anatomical variation is relatively common and is important to be aware of in medical practice, as it can have implications for surgical procedures and interventions involving the liver and its blood supply.
