12 Digestive Urinary Concept Map: Andrew Sanchez-Vasquez Period:5
Major Organs of the Digestive System
Accessory Organs
Salivary Glands(Secrete Saliva,Moistens and dissolves food particles)
Liver(Reddish Brown,Largest internal organ,Filters Blood and removes foreign substances)
Gallibladder(Pear-Shaped Sac,Interior surface of the liver, stores bile between meals and reabsorbs water)
Pancreas(Both Endocrine and Exocrine Gland, Aids Digestion)
Alimentary Canal(Superior-Interior,8 Meters,Food Passageway)
Pharynx(Called the Throat,Passageway for food and air,leads to esophagus)
Esophagus(Muscular Tube leading from pharynx to stomach.Soft,Extends downward)
Stomach(J-Shaped Muscular,Upper Left Abdominal Quadrant,Propels Food to small intestine)
Small Intestine(Long Tubular, Receives Chyme from stomach and finishes digestion of nutrients
Large Intestine(1.5 Meters Long,Doesn't digest nutrients, Mucus helps)
Mouth(First portion,Receives Food,Begins Mechanical Digestion)
Rectum(Interior Part of large intestine, Receives waste and stores in Anus)
Anus(Opening for waste to leave body)
Major functions of the urinary system
3.) Helps Control red blood cell production and blood pressure
2.) Regulates PH and Body Fluid Volume
1.) Filters Salts and wastes from the blood, maintains normal concntrations of electrolytes and water
Major Organs of the Urinary System
Ureatha(Urine passes from the bladder to outside the body)
Kidneys(Bean-Shaped,Posterior Wall of Abdominal Cavity,Removes Waste)
Renal Pelvis(Collects Urine, Funnel Shaped passes it to the ureter)
Ureters(10-13 inches long, Receives the urine from kidneys and carry it to the bladder)
Bladder(Muscular Hollow,temporarily holds urine)
Digestive Enzymes(Including name and functions)
Nucleases(Pancreas,Nucleic Acids to Nucleotides)
Salivary Amylase(Salivary Glands, Breaks down Starch)
Pepsin(Gastric Chief, Begins Protein Digestion)
Pancreatic Amylase(Pancrea cells,Breaks down starch into disacharides)
Lipase(Pancreas,Breaks down parts into fatty acids)
Layers of the GI Tract (Including stomach)
Mucosa(Inner Layer of the wall,Protect tissues of the canal,carries on secretion and absorption of dietary nutrients)
Submucosa(Lies under mucosa,Nourishes the surrounding layers of the canal)
Muscularis(Consits of two layers of smooth muscle, Inner circular layer and outer longitudinal layer, propels food through the canal)
Serosa(Outer Serous Layer,Protects underlying tissues)
Location of digestion and absorption of each macromolecule
Duotenum(Shortest and Most fixed portion,Helps break food down)
Jejunum(2/5 of small intestine,Absorbs sugars and amino acids)
ileum(Most distal portion,absorbs any remaining nutrients that didn't get absorbed)
Nephron anatomy and physiology
1.Glomerulus(Coil of capillary lobes, receives blood from the afferent arterioles,Non-Selective of plasma substances)
2.Glomerular Capsule(Double walled cup that surrounds the glomerulus and collects filtrate from the blood)
3.Proximal Convoluted Tuble(Consists of cells containing mitochondria, Primary site of tubular reabsorption)
4.Descending Limb(Reduce the volume of the urine while reabsorbing sodium and chloride)
5.Nephron Loop(Permeable to water,not solutes)
6.Ascending Limb(Mostly permable to solutions and not water)
7.Distal Convoluted Tubule(Site of Tubular reabsorption and secretion where final adjustment of the urinary compostion)
8.Collecting Duct
Disorders of the digestive and urinary systems
Colon Cancer(located at the digestive tract's lower end,Early cases can begin as noncancerous polyps)
Urinary Tract Infection(Bacteria from skin,higher chance if you have bad immune system,Cause Pelvic pain)
Pancreatitis(Inflammation of Pancreas,1/3 of causes-cause unknown)
Kidneys Stones(Mineral Deposits that form in kidney,sever pain in the side and back, no cure)
Gall Stones(Can block bile duct causing pain and digestive disorders, Surgical removal of gallbladder)
Mumps(Viral Infection that affects salivary glands, spreads person to person, Preventable by vaccine)
Major functions of Digestive System
Mechanical(Breaks down Large pieces of food into food; smaller ones; chemical composition isn't changed by this process)
Chemical(Breaks down large nutrient molecules into smaller chemicals, by breaking chemical bonds)
