Alyssa Villanueva p.7 Digestive Urinary System
Major functions of the digestive system
digestion - mechanical and chemical break down of foods and absorption of nutrients
chemical
breaks down large nutrient molecules into smaller chemicals by breaking down bonds.
mechanical
breaks down large pieces of food into to smaller ones by chewing
Nephron anatomy and physiology
physiology
renal tubule is proximal from the convoluted tubule
nephron is a unit of the kidney
renal corpus is located in the renal cortext
anatomy
renal tubule is a connecting duct for urine
renal corpus - the first step of the production of urine
there about 1 million nephrons in each kidney
Major organs of the digestive system
gallbladder
stores bile between meals and reabsobs water to concentrate the bile
liver
stores glycogen, viatmins A,B12,D iron and filters blood
pancreas
produce pancreatic juices that aids in digestion
small intestine
absorbs digestive ends and recieves chyme from stomach
stomach
helps break down food even more and absorbs the nutrients
large intestine
absorbs water, electrolytes and forms and stores fecees
pharynx & esophagus
helps push food down into the stomach (swallowing)
Digestive enzymes (including names and functions)
stomach
helps break down food
galbladder
stores bile
liver
absorbs and receives digestive chyme
Location of digestion and absorption of each macromolecule
lipids
liver
proteins
carbohydrates
carbohydrates
liver
vitamins
lipids
minerals
viatmins
Disorders of the digestive and urinary systems
gerd
a chronic disease that occurs when the seophegal sphinter relaxes
inflammatory bowel disease
sores that develop the lininng of the stomach
cholcystitis
an inflammation in the gallbaldder
peptic ulcers
chronic complex intestinal contion that causes innflammation in digestive system
colon disease
disease in the colon
bladder cancer
cells that grow abnormally in the bladder
uti
uncountable and or life threatening
kidney stones
high levels of minerals and salt stones can form
Major organs of the urinary systems
ureters - transports urine from kidney / bladder
urinary bladder - stores urine
kidneys - filters blood
urethra - conveys urine to the outside of the body
Layers of the GI tract (including stomach)
muscularis
consists of 2 layers of smooth muscle : inner circular layer and longitudinal layer
propels food through the canal
serosa
outer layer or visceral peritoneum
protects underlying tissues and secretes serous fluid to reduce friction between organs
submucosa
lies under the mucosa
nourishes the surrounding layer of the canal
mucosa
inner most layer
protects tissue canal and carries on secretion and absorption of dietary nutrients
Major functions of the urinary system
the major functions of the urinary system : filters out salts, and waste from the blood, helps maintain a normal concentration of electrolytes and water. regulates pH and body fluid volume
