the abdomen; where it splits into two smaller arteries (iliac)
...

• Diaphragm: located below the lungs; is the major muscle of respiration (large dome-shaped muscle)
...
Attached to the pyloric
sphincter of the stomach on its superior end and to the jejunum of the small intestine on its inferior end
...
Approximately 8 inches long;
running behind the trachea and heart, and in front of the spine
...


• Hepatic Vein: Carry oxygen-depleted blood from the liver to the inferior vena cava
...


 Hepatic Portal Vein: a vessel that moves blood from the spleen and gastrointestinal tract to the liver
...

• Inferior Vena Cava: empties into the right atrium of the heart, and runs alongside the right vertebral column of
the spine
...

○ Inferior pole (Left and Right)
• Liver: the liver is the largest internal organ, about the size of a football, it is located mainly in the upper right
portion of the abdomen, beneath the diaphragm and above the stomach
...

• Mesenteric Artery (superior): arises from the anterior surface of the abdominal aorta, just inferior to the origin of
the celiac trunk
...

○ Body
○ Head: on the right side of the abdomen and is connected to the duodenum (first section of the small
intestine) through a small tube called the pancreatic duct
...
It covers
the upper surface of the diaphragm and is reflected over structures within the middle of the thorax
...

• Perirenal Fat:
• Renal Artery (Left and Right): normally arise off the side of the abdominal aorta, immediately below the superior
mesenteric artery, and supply the kidneys with blood
...

• Renal Vein (Left and Right): drain the kidney
...
They carry the
blood filtered by the kidney
...
It is located inside the
abdominal region
...
They connect the kidney to the inferior vena cava
...

• Rectus Abdominis Muscle: located in the front of the body, beginning
at the pubic bone and ending at the sternum
...

• Ribs
• Small Bowel: (small intestine) is about 20 feet long and about an inch in diameter
...

• Spinous Process of Vertebra: the bony projection off the posterior (back) of each vertebra
...


• Spleen: largest organ in the lymphatic system
...

• Sternum: (breastbone) is a long flat bone shaped like a necktie located in the center of the chest
...

○ Xiphoid Process: The smallest and most inferior region of the sternum
...

○ Body: the main part of the stomach, between the upper and lower parts
...

○ Greater & Lesser Curvature: the medial and lateral borders of the stomach are curved, forming the lesser
and greater curvature
...

 Lesser: forms the shorter, concave, medial surface of the stomach
...
There are two ureters, one
attached to each kidney
