Digestive System and Urinary Concept Map Ms. Yang Period 1, Ana Chen
MAJOR FUNCTIONS:
-
Urinary Tract: produces, stores, filters and eliminates wastes from the body in the form of excretes.
NEPHRON
ANATOMY: kidneys are located at the rear wall of the abdominal cavity just above the waistline and are protected by the ribcage They are about the size of your fist.
Physiology: regulation of electrolytes, maintenance of acid–base balance, and the regulation of blood pressure (by maintaining salt and water balance). They serve the body as a natural filter of the blood and remove wastes that are excreted through the urine.
MACROMOLECULES
Proteins: Gastric juices absorb and cut into amino acids. then goes from the intestinal lining into the pancreas then into the intestine and the bloodstream.
Lipids: mostly fats, mostly in the small intestine, bile in the liver, stored and released from the gall bladder and then reconverted and the given to the rest of the body.
Carbs: chewed then swallowed, moved down the esophagus, then stomach, then small intestine where enzymes are released into the pancreas which breaks them down into simple forms that are absorbed into the bloodstream.

Layer of the GI TRACT
Submusosa: loose connective tissue layer, with larger blood vessels, lymphatics, nerves, and can contain mucous secreting glands.
Muscularis Propia: the inner layer is circular, and the outer layer is longitudinal. These layers of smooth muscle are used for peristalsis (rhythmic waves of contraction), to move food down through the gut.
Mucosa: provides vascular support for the epithelium, and often contains mucosal glands.
Adventia Layer: Outermost layer of loose connective tissue - covered by the visceral peritoneum. Contains blood vessels, lymphatics and nerves.
DISORDERS:
Urinary: urinary incontinence: when you cannot control your urine flow..
Kidney failure: results in the loss of filtration and the use of dialysis.
Bladder infections: caused by buildup of bacteria
Digestive: Crohn disease, chronic inflammation of the digestive tract,
Jaundice: result of liver failure due to bile buildup
Appendicitis: inflammation of the appendx
