Pylorus- The terminus of the stomach. Opens to the duodenum. Greater curvature- Convex lateral surface of the stomach Lesser curvature-Concave medial surface of the stomach Small intestine- Largest part of the alimentary canal mainly located in the umbilical region. Size of enzymatic digestion and absorption, propulsion, and mechanical breakdown. Contains Enterocytes and goblet cells. Duodenum- Secondary Peritoneal region of the small intestines that is the first 5% of the small intestines. Receives bile and enzymes from the gallbladder and pancreas. Jejunum- Intraperitoneal portion of the small intestines that is 40% of the composition. Is located in the left umbilical region. Ileum- Intraperitoneal portion of the small intestines that makes up the remaining 60%. Large intestine- Part of the alimentary canal that functions to digest some, absorb water and electrolytes, propagate food down the canal, and defecate waste. Cecum- Located in the right iliac region. Is the opening of the Ileum into the large intestines. Ileocecal valve- Formed by two layered mucosa that opens when the stomach is filled with food and closes as the cecum streches. Located between the Ileum and large intestines. Ascending colon-secondarily retroperitoneal portion of the large intestines thats located in the right lumbar region, from the cecum connects to the transverse colon. Transverse colon- Intraperitoneal portion of the large intestines that is located in the umbilical region that extends from the ascending and descending colon Descending colon-intraperitoneal portion of the large intestines that is attached to the transverse and sigmoid colon. Sigmoid colon- S shaped, located within the true pelvis. Attaches to the descending colon leading to the rectum. Rectum- Joins the sigmoid colon and leads to the anal canal. Contains several bends that act as valves. Greater omentum- Dorsal Mesentery that connects the greater curvature of the stomach to the posterior abdominal wall. Lesser omentum- Ventral mesentery that runs from the liver to the lesser curvature of the stomach to the duodenum. Liver- Largest gland in the body. Produces bile that helps emulsify fat, stores glucose as glycogen, detoxifies drugs and poisons, makes blood proteins and replaces blood, processes fats and amino acids, and stores certain vitamins. Lies in the left hypochondriac and epigastric region. Right lobe- Larger portion of the liver that contains the gallbladder. Left lobe- Smaller portion of the liver. Right and left hepatic ducts- Carry bile from the right and left liver lobes and fuse to form the common hepatic duct. Common hepatic duct- Extends inferiorly from the right and left hepatic ducts towards the duodenum. Common hepatic artery Hepatic portal vein Hepatic veins Gallbladder- Muscular sac located on the visceral surface of the right lobe of the liver in the left hypochondriac region. Stores and concentrates bile produced by the liver. Cystic duct- Runs from the gallbladder to the common hepatic duct and forms the bile duct. Bile duct- Composed of the common hepatic duct and the cystic duct. Empties bile from the gallbladder into the duodenum Pancreas- Exocrine and endocrine gland. Secretes insulin and glucagon to lower or raise blood sugar levels. Produces digestive enzymes that exit through the pancreatic duct into the duodenum. Located inferiorly to the stomach. Pancreatic duct- Runs throughout the whole pancreas. Serves as the vessel where digestive enzymes travel to the duodenum. Kidney- Lie retroperitoneal to the posterior abdominal wall. Maintain the purity and chemical constancy of the blood and other body fluids, send toxins, metabolic waste, and excess water and ions out of the body through urine. Hilum- Position of the kidney where ureters, nerves, and vessels enter and exit the renal pyramid of the kidney. Fibrous capsule- Thin tough layer of dense connective tissue that adheres directly to the kidney which maintains the shape and acts as a barrier to prevent infection from outside sources. Renal cortex- More superficial region of the kidney that appears lighter and has a granular appearance. Is the location of cortical nephrons. Renal medulla- Deep to the cortex. Is darker and consists of cone shaped areas called renal pyramids. Renal pyramids- Cone shaped masses located in the medulla that exhibit striations due to urine collecting tubules. Renal column- Inward extension of the cortex that separates the renal pyramids from eachother. Renal pelvis- Flat, funnel shaped tube that is an extended part of the superior ureter. Minor calyx- Cup shaped tubes that enclose the papillae of the renal pyramids. Major calyx- Large branch extensions of the renal pelvis. Renal artery- Branch of the abdominal aorta that supplies roughly 25% of the hearts systemic output to the glomerulus for filtration. Renal vein- Vein that merges with the inferior vena cava, returning filtered blood from the kidneys. Ureter- Urine collected from the renal calices collect in the bladder through this vessel. Begins around L2 near the renal pelvis and enters the bladder obliquely preventing backflow. Contains three layers. The mucosa is transitional epithelia, the muscularis contains longitudinal, circular and another longitudinal layer. The adventitia is composed of connective tissue. Bladder- Collapsible muscular sac that stores and expels urine. Lies posterior to the pubic symphysis. In males it is anterior to the rectum and in femails it is anterior to the vagina and uterus. Trigone- Is located near the opening of the ureter and urethra, which forms a triangular region on the posterior wall.
