Urinary & Digestive System
Digestive System Orders
Gastroenteritis
Dehydration
Inflammation of mucous membrane lining of the stomach & intestine
Caused by virus
Hepatitis A
Spread through contaminated food & water
infectious hepatitis
Caused by virus
Pancreatitis
Inflammation of pancreas
Sometimes associated with chronic alcoholism
Cirrhosis
75% caused by excessive alcohol consumption
Chronic progressive disease of the liver
Normaltissue replaced by fibrous connective tissue
Gingivitis
Inflammation of the gums
Cholecystitis
Inflammation of the gall bladder
Gastroesophageal Reflux Disease (GERD)
Problem with cardioesophageal sphincter then you have a condition that can give you heart burn
Also called Acid Reflux
Urinary Disorders
Internal bleeding in urinary tract
Urine looks pink (unless you recently eaten beats)
Dysuria
From holding urine
Difficulty/pain in passing urine
Kidney Infection
Inflammation of kidney due to bacterial infection
Cystitis
Inflammation of the bladder
Diuresis
Increase in the production of urine
Urethritis
Inflammation of the urethra
Bacterial or viral infection causes swelling & irritation of the urethra
Diabetes Melltus
Urine smells & contain a lot of glucose
Urinary Tract Infection
Urineis cloudy with white blood cells
Proteins
Working out too much, pregnancy, high blood pressure, heart failure, severe hypertension
Proteinuria Albuminuria
Digestive System Function
Break down the food & then produce some chemicals that will help break down. Then passed along the wall of digestive tract & carried by cardiovascular system to tissue where it is used for producing enery
Consists of organs that are involved in the breaking down of food into molecules that can pass through the wall of the digestive tract & can be take up by the cells
Walls of the GI tract
From the most inner layer or lining to the exterior
Mucosa (in contact with passing food)
Submucosa
Muscularis or muscular layer
Serosa
Regions of the Stomach
Cardiac Region
Near heart
Fundus
Dome shaped, filled with gas
Pyloric Sphincter
Controls food leaving stomach & entering small intestine
Pylorus
Funnel shaped end
Alimentary Canal (Gastrointestinal Tract)
Small Intestine
Muscular tube extending from the pyloric sphincter
Chemical digestion of fat begins
Site of nutrient absorption into blood & lymphatic vessels
Where most chemical digestion of all food occur by enzymes
Stomach
Food mixes with gastric juice to make chyme
J-shaped, acts as a storage tank for food
Rugae- internal fold of stomach mucosa
Food empties into duodenum of small intestine at the pyloric sphincter
Located left of the abdominal cavity in left hypochondriac region
Only absorption that occurs is water, alcohol, some vitamins, & aspirin
Esophagus
Food transported by peristalsis
Located posteriorly to the trachea
No digestive function, only passage for food & water
Mouth
Opening of the oral cavity
Contains teeth, salivary glands, tonsils, & tongue
Mixing of food with salvia by the tongue to make bolus
Intiates of deglutition (swallowing)
Pharynx
Oropharynx- located posteriorly to mouth, passage for food, water & air
faryngopharynx-inferior to oropharynx
Involves in regulation, forcing bolus from the moth to esophagus
Large Intestine
Does not participate in digestion but resident bacteria digest remaining nutrients
Eliminates indigestible food from body to feces
Rectum- stores feces until it is detected
Absorption of water & electrolytes, produce vitamins
Anus
Presence of feces in rectum triggers defecation reflex
Eliminates feces from rectum to exterior
Internal- made up of involuntary skeletal muscle
External- voluntary skeletal muscle
