Digestive and Urinary System
stomach is mainly composed of the epithelial, muscular and connective tissue
Major Functions
urine chemical make up:
process of urine release:
Peristalsis, involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionaly in other hollow tubes of the body, that occur in progressive wavelike contractions
calories/ fats/ carbohydrates
components of urinary system:
fats (lipids); major storage of energy in the body
recommended adult calorie: 1500-2500 per day
mechanical breakdown
propulsion
digestion
ingestion
absorption
defecation
chloride
sodium
water
potassium
bladder
ureter
kidneys
filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine
expands as it fills with urine
carry urine from each of the kidneys to the bladder
purpose
muscles of the urethral sphincters relax allowing urine to pass through the urethra
eliminate waste from the body, regulate blood volume and bld press., control levels of electrolytes and metabolites and regulate bld. pH
carbohydrates: glucose, starch, cellulose
components of digestive system:
large intestine: pushes poop to the rectum
small intestine: break down food more to absorb vitamins, minerals, and proteins
esophagus: moves food to the stomach
rectum: where poop exits
mouth: covers food with saliva, breakdown
stomach: its a mixter
pancreas: produces insulin
salivary glands:three pairs of exocrine glands in the mouth that secret saliva; parotid, submandibular, and sublingual gland
kidney: filters
gall bladder: an organ that stores bile and releases it as needed into the small intestine
liver: processes and delivers nutrients to the rest of your body when needed
