To improve repair techniques and reduce long-term complications involving visceral arteries, it is crucial to understand in vivo arterial geometry and the deformations due to visceral organ movement with respiration. The hilum is a small area for the renal artery and nerves to enter the kidney, and for the renal vein and ureter to exit. Spleen works with the Stomach to regulate the transport and metabolism of water and nutrients. The spleen is located in the upper right quadrant of the abdomen, it’s located under the rib cage and diaphragm.The roughly fist sized organ, which is the largest lymphoid organ, attaches to the lateral border of the stomach by means of the gastrosplenic ligament and is about 5 inches in length. The liver helps digest food and remove toxins from our bodies, but it serves many other purposes. The glomerulus is where filtration occurs. This allows movement to occur, while still keeping all structures anchored it in place. This organ is the largest peritoneal fold in the body, the fold is transparent and riddled with gastroepiploic arteries and drainage veins. A nephron is composed of 2 structures: the renal corpuscle and the renal tubule. Video: https://www.youtube.com/watch?v=BtqlMr1rUT8. It produces numerous hormones and other chemical mediators that have many detrimental effects on all systems of our body, including risk of diabetes, cardiovascular disease, low testosterone, erectile dysfunction (ED) and premature death. Parasympathetic and sympathetic impulses also trigger nerves to inhibit or promote activity. The greater omentum has seven important functions: The mesentery surrounds many of the visceral organs in the abdominal region. They descend retroperitoneal (behind the peritoneum) through the abdominal cavity and across the sacroiliac joint, where they then enter the posterolateral corner of the urinary bladder obliquely. Food travels through the tube “outside of the body” in the lumen, during this process the body extracts what it needs, and disposes of what it doesn’t. Anterior frontal section diagram of the gross anatomy and blood supply of the right kidney. When the detrusor muscle (de-tru’sor; “to thrust out”) contracts during urination, it squeezes the urine out of the bladder. The function of this sphincter is to keep the urethra closed when urine isn’t being passed through. A Kid's Guide (about donating and transplanting organs) Education for Secondary School Students . Let's take Spleen as an example for illustrating the interactions of organ functions. Higher up, above the ribs, are the thyroid gland and the trachea. The cecum is continuous with the ascending colon, it runs superiorly on the right side of the abdomen from the right iliac fossa to the right lobe of the liver. The sigmoid colon is the link between the descending colon and rectum, it is S-shaped (hence “sigmoid”) and turns into the rectum at the third sacral vertebrae. In a state of emptiness the bladder collapses into its pyramidal shape and the inner mucosa forms folds, or. Urachus means “urinary canal of the fetus” and is a closed part of what used to be an embryonic tube called the allantois. Macrophage contained within protects against abdominal infections, the greater omentum can actually move to infected areas to send white blood cells to help fight off the infection. Figure 4.0. An organelle in the liver called peroxisomes detoxifies other poisons such as alcohol. Organ. The most superior portion of the greater curvature and the fundus (see figure 3) are supplied by the short gastric arteries, branches of the splenic artery. Truncal Obesity is an accumulation of fat around the waist area, including the torso. Where the bladder and urethra meet, the detrusor muscle thickens to form the internal urethral sphincter. During rest the kidneys receive about one quarter of the heart’s systemic output via the renal arteries. The colon is further subdivided into the ascending, transverse, descending and sigmoid colon. At the right colic, or hepatic, flexure, the colon turns left. Intense, sudden, stabbing pain may be a kidney stone.These are mineral deposits that can grow large enough to block a ureter, a tube that connects your kidney … The esophagus lies posteriorly to the trachea, and is continuous with the laryngeal part of the pharynx. The bile duct is connected by the common hepatic duct and the cystic duct. Fifty-seven patients (71%) had single organ involvement, and 23 (29%) had multiple organ involvement. The Esophagus, sometimes referred to as the Oesophagus, is the 25cm muscular tube that connects the pharynx (throat) to the stomach. Treatment is available for Chron’s disease although there is no cure. The outer tissue of the ureter wall is the adventitia composed of typical connective tissue. Within the cardia is the lower esophageal sphincter. Each region of the stomach has a unique composition of mucosal glands.The layers of the stomach are summarized in table 1. https://www.youtube.com/watch?v=BtqlMr1rUT8, Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License, Fats/lipids into fatty acids and glycerol with the help from bile from the gallbladder, Proteolytic enzyme (include Proteases, peptidase).
