Ashley Gonzalez P1: Digestive Urinary
Major Functions of Digestive System
take in food,
break food down
absorb molecules into blood stream
rid of any indigestible
Major Organs in Digestive System
Alimentary Canal
breaks down the food
mouth
swallowing
pharynx
allows food to pass
esophagus
passage to stomach
stomach
small intestine
large intestine
anus
Accessory Digestive Organs
teeth
tongue
gallbladder
storage of bile
digestive glands
salivary glands
liver
break down bile
pancreas
supplies enzymes
Location and Absorption of each Macromolecule
Carbohydrate
mouth small intestine
glucose and galactose are absorbed via cotransport with Na+, frucose passes via facillitated diffusion
Protein
stomach, small intestine
amino acids absorbed via contrasport as well as some dipepitides and tripeptides, amino acids leave epitheleal cells via facillitated diffusion
Fat
mouth, stomach, small intestine
fatty acids and monoglycerides enter intestinal cells via diffusion, then recombinedx to form triglycerides then combined with other acids, absorbed fatty acids move into capillary
Nucleic Acid
small intestine
active transport via membrane carriers
absorbed into capillary blood in villi and transported to liver via the hepatic portal vein
Major Functions of Urinary System
regulate total water volume
regulates ion concentrations
excrete metabolic wastes, toxins, drugs
Major Organs of Urinary System
kidney
ureters
transport urine from kidneys to urinary bladder
urinary bladder
temporary storage for urine
urethra
transport urine out the body
Nephron Anatomy and Physiology
Renal Corpulscle
glomerulus
allows for efficent filtrate formation
porus capillaries
composed of fenestrated endothelium
Glomerular capsule
bowmans capsule
filtatrion slits between foot processes which allow filtrate to pass
Renal Tubule
Proximal Convoluted Tubule
confined to cortex
reabsorbtion and secretion
Nephron Loop
descending limb
continous proximal tubule
descendin thin limb
ascending limb
thick ascending limb
tthin in some nephrons
Distal Convoluted Tubule
more secretion than absorpation
confined to cortex
Digestive Enzymes
proteases
secreted in inactive for to prevent self digestion
amylase
breakdown carbrohydrates
lipases
breakdown lipids
nucleases
break down nucleic acids
Layers of GI tract
mucosa
tunic layer that lines lumen
secretes mucus
absorbs end products of digestion
protects against infectious disease
submucosa
has abundant amount of eslastic tissue
supply surrounding GI tract
aereolar connective tissue
serosa
muscularis externa
