Small Intestine
Major functions of the
digestive and urinary systems
digestive tract
series of tubelike organs that are joined end and end and are used for digestion
esophagus
squeezes food with rhythmic muscle contractions
stomach
grinds food and breaks it up with stomach acid
anus
way solid waste (feces) leaves the body
pancreas
organ that makes fluid that protects the small intestine from the acid
gallbladder
stores bile produced by the liver
liver
store nutrients, break down toxins and break up fat
kidney
main organ in the urinary system
ureters; urethra
carry urine from the kidneys to the bladder
carries urine to the outside of the body
bladder
stores urine
small intestine
absorbs nutrients and transfers them to the bloodstream
layers of the GI tract
Mucosa
Innermost layer that lines the lumen
submucosa
Layer superficial to the mucosa
muscularis externa
Layer superficial to the submucosa
serosa
outermost layer
Nephron anatomy and physiology
Collecting duct
Variable reabsorption of water and reabsorption or secretion of sodium, potassium, hydrogen and bicarbonate ions
Nephron loop descending limb
Reabsorption of water
Proximal convoluted tubule
Reabsorption of water, ions and all organic nutrients
Nephron loop ascending limb
Reabsorption of sodium and chloride ions
Distal convoluted tubule
Secretion of ions, acids, toxins; variable reabsorption water and sodium ions
Glomerular capsule
Production of filtrate
disorders of the digestive and urinary systems
