Q

peristalsis

A

the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wave-like movements that push the contents of the canal forward.

Q

liver

A

many different functions in many body systems

detoxify blood, breaking down toxins

storage of nutrients
makes bile (breaks down fatty foods)
breaks down fats and helps remove wastes from the body
located in RUQ
averts glycogen to glucose for energy

made to digest fats b/c fats are hydrophobic, secreted into the duodenum

25
gallbladder
stores and concentrates bile (small sac located interior to the liver)
26
pancreas
produces insulin to break down blood sugar in blood outside the D.S. and enzymes for digestion
27
anorexia
lack of or no appetite
28
ascites
sign of end stage liver disease, edema in abdomen (think cankles) fluid accumulation in abdomen
29
borborygmus
noises your digestive system makes as it digests food and moves it around
30
constipation
hardening/backup of stool due to dehydration or lack of fiber in diet
31
dehydration
lack of water in body
32
diarrhea
excessive flow of feces, lack of water uptake from large intestine (your large intestine isn't intaking the water from the food you eat)
33
dyspepsia
difficulty of digestion/indigestion
34
dysphagia
difficulty swallowing
35
jaundice
yellow pigmentation of skin due to cirrhosis of liver, liver is responsible for breaking down RBC with bilirubin but when cannot be excreted it builds up which makes you yellow
36
bilirubin
in RBC's which help carry oxygen
37
cirrhosis
scarring of the liver usually due to 2 things: alcohol + hepatitis, not able to filter toxins; hepatic backup like pulmonary backup; fluid seeps out of blood vessels and settles in the abdomen
38
hepatitis
viral infection, blood borne, hep. b and c are in the U.S.; get it through illegal drug use (the needles) and sexual intercourse, cirrhosis can be from hepatitis
39
signs of liver disease
ascites, jaundice, esophageal varices
40
esophageal varices
veins that supply the esophagus rupture b/c of cirrhosis (lots of blood - swollen veins) liver is scarred --> backup --> veins backup --> allows fluids to seep through veins --> abdomen if they start to bleed and it goes into the stomach they will throw up blood, but if it is a slow bleeding it will be digested and will not know they have an internal hemorrhage
41
emesis
vomiting (stays out)
42
eructation
burping
43
flatus
passing gas
44
halitosis
bad breath
45
hematemesis
vomiting blood
46
hematochezia
defecation of blood
47
nasuea
feeling before vomiting
48
regurgitation
return of swallowed food from the stomach (goes back down)
49
ulcer
erosion of mucosal membrane anywhere along the digestive tract, must let it heal, constantly open or exposed to enzymes if in the stomach
50
appendicitis
inflammation of the appendix, LRQ, laparoscopic appendectomy, can be very bad if the appendix bursts b/c it has a lot of bacteria and it can get into the rest of the body --> can lead to sepsis, pain
51
what are the 3 scopes used for a laparoscopic appendectomy and what is it used for
1st is put into the umbilicus, 2nd and 3rd are the pinchy one and the cauterization tool, it is to see if the appendix is swollen, if so you do an appendectomy
52
what does laparoscopic mean and why do they use it
the viewing with a scope of the abdomen, used to reduce blood loss
53
what medicine do you take for sepsis
antibiotics
54
celiac disease
gluten allergy, inflammation --> affect absorption of nutrients, pain, peristalsis is affected, one place at one time
55
cholecystitis
inflammation of the gallbladder
56
choleithiasis
presence of stones in gall bladder, unknown reason why, as long as the gallbladder can excrete bile its ok but if it blocks it, it's bad and can cause inflammation
57
what surgery do you do to remove stones in the gall bladder
cholecystectomy
58
what is the treatment for cirrhosis
abdominocentesis, but slowly b/c too much at once can cause arrhythmia
59
crohn's disease
autoimmune condition that cause inexplicable inflammation anywhere in the digestive tract, affects absorption of nutrients, peristalsis is affected, pain, can be in many places
60
dental carries
cavities
61
enteritis
small intestine inflammation
62
gastroenteritis
stomach and small intestine inflammation
63
hiatal hernia
stomach ruptures through the diaphragm, can go unnoticed, GERD is associated with this, surgery to push stomach back into place
64
Ileus
obstruction of the small or large intestine
65
what happens if you have a blockage
there is a high risk of infection, pain, and no nutrient absorption
66
intestinal adhesions
type of obstruction
67
intussusception
type of obstruction
68
volvulus
twisting of the intestine causing blockage
69
irritable bowel syndrome
IBS, autoimmune, patient switches from diarrhea to constipation and back
70
irritable bowel disease
same as syndrome
71
peptic ulcer
ulcer in the stomach, difficult to treat b/c you need to just let it heal but b/c of constant exposure to enzymes and acid it is hard to heal, another reason why you might have hematochezia
72
periodontal disease
gingivitis on steroids, gum disease, gums get so infected with bacteria b/c of so many cavities, gums then recede so teeth will eventually fall out
73
abdominal ultrasound
sound waves
74
barium enema; lower gastrointestinal (LGI) series
a test to see any blockage in the LGI
75
computerized tomography (CT)
high powered xray
76
endoscopy
viewing of the UGI, scope is pushed down throat, for proximal jejunum and up
77
occult blood test
test to detect if there is digested blood in the stool
78
upper gastrointestinal (UGI) series
barium swallow, drink up the chalky stuff
79
colonoscopy
viewing of LGI, distal jejunum and down
80
acid blocker
pepcid AC is an example; over the counter meds
81
antibiotic
self explanatory, bacterial stuff
82
antiemetic
anti nausea
83
bariatric surgery
obesity surgery, lap band, gastric bypass
84
laxative
loosens stool to help with constipation
85
surgery (general)
does laparoscopic "-ectomy's"
86
lap band
stops you from eating too much, tricks your brain into thinking your full, semi perminate
87
gastric bypass
perminate, gastric pouch is inserted
