hollow muscular tube from the mouth to the **** the length varies between individuals
typically measuring during life around 25 feet and after death close to 35 feet
which tissue layer of the alimentary canal coordinate rhythmic peristaltic contractions of the
muscles which results in the mixing and the forward propulsion of food bolus through the
stomach and intestine - Answer muscularis
the muscularis consists of two smooth muscle layers A circular inner layer and a longitudinal
outer layer and coordinates rythmetic peristaltic contractions of the muscles resulting in the
mixture and forward propulsion of food bolus through the stomach and intestines
Which tissue layer of the alimentary canal is involved when a patient is experiencing the pain of
bowel inflammation - Answer serosa
The serosa which covers the structures within the peritoneal cavity is in continually with the
visceral peritoneum and associated with pain of bowel inflammation
What complication may be avoided when stomas are matured (everted) at the time of surgery -
Answer serositis
The outer layer of the bowel is serosa and exposed to air it can lead to necrosis and sloughing
called serositis inflammation of the serosa if a stoma is not everted at the time of creation, the
seroitis can cause a partial or complete obstruction of the non matured stoma
Which post surgical patient would the woc nurse monitor for percutaneous anemia due to
impaired absorption of vitamin B12? - Answer A patient with an ileostomy will have
significant links of the terminal ileum resected and may require lifelong vitamin B12
replacement to prevent prayer continuous anemia improve fat intolerance and reduce weight
loss
Which structure of the small intestine may take on some of the functions of the colon when the
colon is surgically removed - Answer villi
Villi are able to transform to some degree elongate or become hypertrophied and thus are
capable to increase the absorbative capacity taking on some of the function of the colon when
the colon is surgically removed
,A patient is undergoing surgery for continent diversion which structure of the small intestine
may be used as a continent mechanism for this patient? - Answer ileocecal valve
the ileocecal valve is smooth muscle that can function to prevent stoma output from a
continent diversion
Of all the organs in the digestive tract which one is considered by some to be the organ of
convenience and is not necessary to sustain life? - Answer colon
The colon function fluid absorption transportation of fecal material and storage is not necessary
to sustain life. the small intestine villi are able to transform to some degree and are able to
increase the absorptive capacity taking on some of the colon function when the colon is
surgically removed
Patient should be positioned on the left side for colonoscopy because of the S shaped curvature
to the - Answer sigmoid colon
the sigmoid: is on the left side of the abdomen and the endoscopist will be able to move the
scope into the S shape sigmoid: if the patient is laying on the left side
Which organ has the ability to regenerate up to 70% to destruction before becoming
symptomatic? - Answer Liver
it is thought that the liver's blood supply and proximity to the individual cells allows the liver to
regenerate
In an individual with an intact bowel, the factor most critical to gas production is - Answer
Dietary factors such as complex carbohydrates
The role of the colon in nutrient absorption is best described as - Answer The colon is
incapable of contributing to nutrient absorption
What are prebiotics? - Answer Undigestible carbohydrates that promote the growth of
beneficial bacteria in the gut.
What are symbiotics? - Answer Protective compounds, such as short chain fatty acids, that
support the growth of beneficial bacteria in the gut.
What are probiotics? - Answer Beneficial bacteria found in the bowel that promote a healthy
gut microbiome.
the functional unit of the kidney is the nephron what is the primary function of this structure -
Answer removing waste and toxic products from the plasma
, and control the composition of body fluids
Which structure of the urinary system assist with urine storage and elimination? - Answer
bladder
the urinary bladder is hollow muscular organ designed to fill with urine at low pressures stores
approximately 300 to 600 MLS urine in the healthy adult and eliminates urine
Which structure of the urinary system is common sight for congenital or acquired obstruction
such as kidney stone - Answer ureteropelvic junction (upj)
the UPJ is a common site for congenital or acquired obstruction that is stones
What is the important function of the urethra? - Answer Maintaining continence. the urethra
has specialized striated muscle that contains both fast twitch and short twitch muscle fibers that
aid in tone of the urethra during periods of sudden increase in abdominal pressure to prevent
urinary incontinence
Which organ adjacent to the kidneys needs to be protected during urinary reconstruction
surgery? - Answer ascending large intestine
organs adjacent to the kidneys include the duodenum, pancreas tail, hepatic flexure of the large
intestine, ascending colon descending and sigmoid colon. Identification and protection by the
surgeon during urinary reconstruction surgery are crucial to prevent life threatening inter and
post operative complications
the kidneys secrete - Answer renin angiotensin aldosterone to regulate blood volume and
pressure
the kidneys possess endocrine like functions by secreting hormones EPO erythropoietin to
promote red blood cell production and renin angiotensin aldosterone to regulate blood volume
and pressure homeostatic mechanisms to maintain narrow blood pH range is primarily done by
the kidneys and lungs to mean hydrogen balance bicarbonate is regulated by the kidneys
What condition might occur when excess of uric acid is precipitated in the blood? - Answer
Gout
Uric acid is a byproduct of purine and guanine metabolism from the intake of meat and seafood
only 10% is excreted in the urine if in excess uric acid may precipitate in blood and cause painful
deposits and joints called gout
What important point should be emphasized when explaining how the renal system works to
regulate the body's fluid and electrolyte balance? - Answer Anti diuretic hormone causes
water reabsorption. Four key points to remember when discussing fluid and electrolyte balance
are as follows
1 aldosterone causes reabsorption of sodium and secretion of potassium
