Digestive / Urinary System Rosa Reyes P.5
Major Functions of Digestive System
Take in food
Break it down to nutrient molecules
Absorb molecules into blood stream
Rid body of any indigestion remains
Major Functions of Urinary System
regulates total water volume and total solute concentration in H2O
Regulates ion concentration in extracellular fluid
Ensuring long- term acid-base balance
Excreting metabolic wastes, toxins and drugs
Produces erythromycin
Activating vitamin D
Carries out gluconeogenesis
Major Organs of Digestive System
Mouth : anterior opening
Tongue : Gripping, repositioning and mixing food
Salivary glands : Cleanse mouth, dissolves food chemicals, moistens food, components into bolus, and begins breakdown of starch
Teeth : in process of mastication / chewing
Major Organs of Urinary System
Uretha
Urinary Bladder
Ureter
Kidneys
Renal veins/ arteries
Digestive Enzymes
Prokaryotes : for proteins
Amylase : for carbohydrates
Lipases : for lipids
Nucleates : for nucleic acids
Loco of Digestion and Absorption of each Macro-molecule
Vitamin Absorption : In small intestine of fat- soluble vitamins are carried by micelles and diffuse into absorptive cells
Electrolyte Absorption : Most ions are transported activity along length and small intestine. Iron and calcium are absorbed in duodenum
H2O Absorption : 9 liters of water most from GI tract Secretions, enter small intestine. Absorbed by osmosis
Layers of GI Tract (including stomach)
Contains 4 regular Tunics, muscular and mucosa are modified. Muscularis external has circular and longitudinal smooth muscle layers and extra 3rd layer, oblique layer. Mucosa layer is also modified and has simple columnar epi entirely composed of mucous cells
Nephron Anatomy and Physiology
Structural and functional units form urine in kidneys
more than 1 million per kidney
Renal Corpuscle
Allows efficient filtration formation of plasma fluid that renal tubules process to form urine
Renal tubule
Proximal convoluted tubule, nephron loop and distal convoluted tubule
Disorders of Digestive/ Urinary
UTI
Enlarged prostate
Nephritis
