Q

How is IRV measured on a BIOPAC spirogram?

A

Take the peak of the TV wave that occurs before the big inhalation and go to the peak of the big inhalation. IRV is the big wave minus the TV wave.

Q

What is considered the normal threshold for FEV1/FVC%?

26
What was the indicator used for carbohydrate digestion?
Lugol's solution
27
What type of epithelium does the duodenum have?
Simple columnar epithelium
28
What is ERV?
Expiratory Reserve Volume
29
What is the normal range for specific gravity of urine?
1.010 - 1.025
30
FEV1/FVC or FEV1 ratio
Exhaled air after 1 second/total exhaled air
31
With biurets, what color indicates presence of proteins?
Purple \*this result could indicate that proteins have not yet digested or there is no pepsin present to digest the protein
32
What were the four components contained in the tube for lipid digestion?
Bile H2O Lipase Bromothylmal blue
33
What kind of epithelium does the kidney have?
Simple cuboidal epithelium
34
What is the spirometry program called?
BIOPAC
35
Average RV for females
1.1L
36
What organ does this belong to?
Ovary
37
What organ does this belong to?
Kidney
38
What are the three structures to ID in the Liver?
Central Vein Hepatocytes Sinusoids
39
What is RV?
Residual Volume
40
large quantities of mucus threads in urine indicate...
infection, especially STIs
41
If FEV1%/FVC ratio is \> 0.7, then
there is a restrictive condition
42
What are the two structures to ID in the uterus?
Endometrium Myometrium
43
FVC greater than 80% of predicted value points to...
airway obstruction
44
What are some examples of airway obstruction?
Emphysema Asthma Bronchitis COPD - chronic bronchitis and emphysema
45
How is ERV measured on a BIOPAC spirogram?
Take the trough of the big exhale to the trough of the TV wave closest to the big inhalation. ERV is the difference between the two waves.
46
What is considered the normal threshold for the FVC ratio?
greater than 80% of the predicted value
47
What is TV?
Tidal Volume
48
What organ does this belong to?
Uterus
49
What is the thing used to measure specific gravity of urine?
urine hydrometer
50
How is TV measured on BIOPAC spirogram
Take the trough of a TV wave and go to the peak of that TV wave
51
With bromothymal blue, what color indicates alkaline and what color indicates acidic?
Blue indicates alkaline and yellow indicates acidic \*Yellow = acidic = fatty ACID
52
With biurets, what color indicates digestion of protein?
lavender/pink indicates presence of shorter chain peptides, meaning protein was digested
53
What are the two structures to ID in the pancreas?
Islets of Langerhans Acini
54
With Lugol's, what color indicates less presence of starch?
Lighter purple/gray \*this color indicates that starch is in process of being digested
55
What kind of epithelium does the esophagus have?
Stratified squamous epithelium
56
What organ does this belong to?
Pancreas
57
What organ does this belong to?
Testis
58
What does the filter for spirometry look like?
a flying saucer
59
What are the three structures to ID in the testis?
Seminiferous tubules Sperm (spermatozoa) Leydig (interstitial) cells
60
What is the reactant, enzyme, and product of carbohydrate (starch) digestion?
Reactant - Carbohydrate (starch aka polysaccharides) Enzyme - Pancreatic and salivary amylase Product - simple sugars such as disaccharides and monosaccharides
61
What is the reactant, enzyme, and product (3) of lipid digestion?
Reactant - triglyceride Enzyme - Lipase Product - fatty acids, glycerol, and some monoglycerides
62
What is the thing that you hook on to the filter for spirometry?
Flow transducer
63
What were the four components in the tube for protein digestion?
Albumin Pepsin HCl H2O
64
What is FRC and how is it calculated?
Functional Residual Capacity ERV+RV
65
What is the reactant, enzyme, and product of protein digestion?
Reactant - protein (produced by chief cells of the stomach) Enzyme - pepsin Product - peptide or shorter chain peptides
