25
Where does the pancreas secrete it digestive enzymes, and where does it secrete its hormones?
Digestive through a system of ducts into the digestive tract Hormones are secreted directly into the bloodstream
26
An abnormal pancreatic function can lead to what?
Pancreatitis or diabetes mellitus
27
What is the function of the spleen?
Filter against foreign organisms that infect bloodstream, filters our old red blood cells from bloodstream and recycles them, acts as blood reservoir
28
What is the minor function of the spleen which is taken over by bone marrow after birth?
Manufacturing of red blood cells only toward the end of fetal life and after birth the function is taken over by the bone marrow
29
What is the largest lymph organ in the body and where is it located?
The spleen is located posterior to the stomach in the left upper quadrant for the abdomen
30
What are the functions of the stomach?
Break down and digest food in order to extract the nutrients from what we eat, stores food so that the meals eaten during the day can provide energy throughout the day, stomach acid aids in digestions as nutrients are absorbed
31
Where is the stomach located?
Under the left diaphragm
32
What is the gastroesophageal junction ?
Indicates the area where the stomach and esophagus join aka cardiac orifice,esophagogastric junction
33
What level does the stomach extend?
T11-L1
34
What is the function of the intestines?
Portion of the digestive tract between the stomach and the anus.
35
The small intestines consists of which sections?
Duodenum, Jejunum, ileum
36
How long is the small intestine?
6meters or 20 feet long
37
What is the function of the intestine?
Small intestine secretes hormone called secretin which stimulates the pancreas to produce digestive enzymes
38
The large intestine is divided into 6 sections known as
Cecum,ascending colon,transverse colon, descending colon, sigmoid colon, rectum
39
What is the large intestine responsible for?
Absorption of water and secretions of solid waste material
40
What is the adrenal cortex?
The outer portion of the adrenal gland, secretes hormones that include corticosteroid hormones (hydrocortisone,corticosterone, aldosterone, androgenic steroids)
41
What is the adrenal medulla?
Inner part of the adrenal gland, not essential to life, helps person cope with physical and emotional stress
42
Which hormones are secreted by the adrenal medulla?
Epinephrine, norepinephrine
43
Where are the kidneys located?
Near the middle of your back, just below the rib cage
44
What is the function of the kidneys?
Process blood and swift out waste products and extra water, which becomes urine
45
What are the nephrons?
Tiny units within the kidneys where the actual filtering occurs
46
Where is the glomerulus located and what is it's function?
Located within the nephron, it is a tiny blood vessel, or capillary, intertwined with tiny urine-collecting tubes called tubules
47
Where can you find the abdominal aorta and what does it supply?
Passes down the back of the chest and abdomen, supplies blood to the lower part of the body and legs
48
What is the peritoneum and what does it contain?
Thin serous membrane that lines the walls of the abdominal cavity, which contains the liver, gallbladder, spleen, stomach, ovaries, and majority of the intestines
49
What are the mesentery?
Peritoneal folds that connect certain parts of the intestines with the abdominal wall, hold them into position and also enclose the vessels and nerves feeding each part
50
What is peritonitis?
Inflammation of the peritoneal cavity, generally from infection from perforated bowl but also occurs frequently in dialysis patients (CAPD)
51
Where is the Supracolic compartment located?
Located above the transverse colon
52
What Is Morisons pouch?
Deepest point of the abdominal cavity in a supine patient and is common site for collection of fluid
53
Where is the infracolic compartment?
Below the transverse colon
54
The right and left parabolic gutters are located where?
Lateral to the ascending and descending colon, the right side if deeper and is another site for free fluid collections
55
What is image reconstruction ?
Filters back projection or the summation method; mathematical function used to reconstruct the image
56
What is the purpose of image compression?
Speed up transmission and reduce storage requirements
57
What is the difference between lossless;reversible and lossy;irreversible image compression?
Lossless; no info lost Lossy; some info lost
58
What are digitally reconstructed radiographs (DRR's)
Images that are created by reconstruction of the data sets into coronal and Sagittal planes, used later in treatment process to match the patient positions and field to DRR
59
What does the retoperitoneum contain?
Kidneys, ureters, adrenal glands, pancreas, duodenum, aorta, inferior vena cava, pelvic structures (bladder, uterus, and prostate gland)
60
At what level are the kidneys located ? Which one lies higher
T12-L4,the left kidney commonly lies higher
61
What are the renal cortex, renal medulla responsible for?
Cortex filters urine and medulla (pyramids) are the beginning of the collection system
62
What is Gerota's Facia?
Functions to anchor the kidneys to surrounding structures to prevent bumps and jolts to the body from causing injury to the kidneys, also acts as a barrier to limit spread of infection that any arise in the kidneys
63
Function of the ureters?
Paired muscular tubes that transport urine to the bladder, originates at the renal pelvis and descends anteriorly and medically to the psoas muscle
64
Adrenal glands function? Location? Characteristics
Productions of steroids and epinephrine, located on tops of kidneys separated by perirenal fat Right adrenal gland lower and V shape Left adrenal gland triangular or Y shape
65
Where is the pancreas located and what is its function?
Lies behind the stomach, extends from duodenum to the spleen, exocrine and endocrine gland Exocrine function secretes pancreatic juice into small intestine Endocrine function secretes insulin and glucagons into the blood stream
66
At what level does the abdominal aorta bifurcate?
L4, bifurcates into the right and left common iliac arteries
67
Where is the celiac trunk located?
Leaves the anterior wall of the aorta just after it passes through the diaphragm
68
At what level is the inferior vena cava formed? What forms it?
Formed by the union of the common iliac wins at approx L5
