Digestive and urinary test Flashcards
Liver
removes excess glucose from the blood stream and stores it as glycogen, destroys old erythrocytes, removes toxins from blood, secretes bile and enzymes which aid in digestion of fat
Gallbladder
stores bile and releases it to the small intestine as needed, bile is used to break apart large fat globules, pear shaped egg sized under liver
Pancreas
soft 6 in gland behind stomach, secretes digestive juices and enzymes into small intestine as needed, aid in digestion and contain sodium bicarbonate to help neutralize stomach acid
Hard/soft palate
bony anterior portion of palate, covered in specialized mucous membranes
flexible posterior portion of the palate, closes off the nasal passage during swallowing
Salivary glands
3 pair, parotid, sublingual, submandibular
Periodontium
bone and soft tissues that surround and support the teeth
Mastication
aka chewing breaking food down into smaller pieces, mixes with saliva and prepares it to be swallowed
Pyloric sphincter
controls flow from stomach to small intestine
Small intestine/peristaltic action
pylorus to large intestine, 20 ft, completes digestion and absorption of most nutrients, 3 parts duodenum, jejunum, ileum, conversion of food into usable nutrients
moves chyme through
Proctologist
Physician who specializes in disorders of the colon, rectum, and anus
Aphthous ulcers
Aka canker sore or mouth ulcers, are grey-white pits with a red border in the soft tissue lining the mouth. Exact cause unknown but associated with stress, certain foods, and fever
Stomatomycosis
Any disease of the mouth due to a fungus
Xerostomia
Aka dry mouth is the lack of adequate saliva due to diminished secretion of the salivary glands
Cleft lip
Aka harelip is a birth defect in which there is a deep groove of the lip running upward to the nose as a result of the failure of this portion of the lip to close during prenatal development
Bruxism
The involuntary grinding or clenching of the teeth that usually occurs during sleep and is associated with tension and stress
Eructation
Act of belching or raising gas orally from the stomach
Hyperemesis
Extreme, persistent vomiting that can cause dehydration
Ileus
Partial or complete blockage of the small and/or large intestine. Caused by the cessation or stopping of intestinal peristalsis
Ulcerative colitis
Chronic condition of unknown cause in which repeated episodes of inflammation of the rectum and large intestine cause ulcers and irritation
Crohn’s disease
chronic autoimmune disorder that can occur anywhere in the digestive tract; however it is most often found in the ileum and colon. It penetrates every layer of the tissue of the affected area. Results in thickening and scarring of the wall of the affected area. very painful
Celiac disease
inherited autoimmune disorder characterized by a severe reaction to foods containing gluten
Jaundice
yellow discoloration of the skin, mucous membrane and eyes. caused by a greater than normal amount of bilirubin in the blood
Functions of the urinary system
-maintaining the proper balance of water, salt, and acids in the body by filtering the blood as it flows through the kidneys
-constantly filtering the blood to remove urea and other waste material from the bloodstream
-converting these waste products and excess fluids into urine to be excreted
Functions of the kidney
constantly filter the blood to remove waste products and excess water
Renal cortex and medulla function
outer region of kidney, contains over a million nephrons
inner region, contains most of the urine collecting tubules
Glomerulus function
clusters of capillaries surrounded by bowman’s capsule where the filtration of blood happens
Renal pelvis function
funnel shaped area where the urine is collected before flowing into the ureters
Ureter and peristalsis function
2 narrow tubes that transport urine from the kidneys to the bladder
Wave like contractions move urine down each tube
Renal failure and hemodialysis
Aka kidney failure is the inability of one or both of the kidneys to perform their functions.
A treatment used to artificially filter waste from the blood when the kidneys fail replace kidney function
Nephrotic syndrome
Condition in which very high levels of protein are lost in the urine and abnormally low levels of protein are present in the blood. This is the result of damage to the kidneys glomeruli. Aka nephrosis
Anuria
Absence of urine formation by the kidneys
Nephrolithiasis
Describes the presence of stones in the kidney
Ureterolith
A stone located anywhere along the ureter
Neurogenic bladder
Urinary problem caused by the interference with the normal nerve pathways associated with urination
Nocturia
Excessive urination during the night
Oliguria
Scanty urination
Incontinence
Inability to control the excretion of urine and feces
Also study
label diagrams in digestive and urinary notes
nocturnal enuresis
Bed wetting/incontinence while sleeping
Close nasal passage when swallowing
Soft palate
Catabolism
Metabolism in which cells and substances are being broken down
