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
