Lab Practical 2 Flashcards
With Lugol’s, what color indicates full digestion?
Yellow or pale yellow
What is specific gravity?
density of a fluid compared to that of distilled water
With Lugol’s, what color indicates the presence of starch?
Dark Purple/Black *this color indicates that starch is present and not yet digested as enough time has not yet elapsed or nor amylase is present
What is VC and how is it calculated?
Vital Capacity IRV+TV+ERV
Average RV for males
1.2L
What organ does this belong to?
Duodenum
With biurets, what color indicates no proteins are present?
pale blue
What is IC and how is it calculated?
Inspiratory Capacity IRV+TV
What is TLC and how is it calculated?
Total Lung Capacity IRV+TV+ERV+RV
What was the indicator used for protein digestion?
Biurets
What are the three structures to ID in the kidney?
Glomerulus
Glomerular (Bowman’s) Capsule
Renal tubule
What were the four components in the tube for starch digestion?
Starch Lugols Amylase H2O
FVC less than 80% of predicted value points to…
restricted lung expansion
What are some examples of restricted lung expansion?
Pulmonary fibrosis Asbestosis Infant respiratory distress syndrome (lack of pulmonary surfactant) Acute respiratory distress syndrome
What are the two structures to ID in the Ovary?
Oocyte
Ovarian follicle
If FEV1%/FVC ratio is < 75%
there is an obstructive condition
What are the four types of urine sediments?
Crystals Cells Casts Mucus Threads
What is the big syringe for spirometry called?
Calibration syringe
How to calculate % of predicted FVC?
Observed FVC / Predicted FVC
What organ does this belong to?
Esophagus
How is IRV measured on a BIOPAC spirogram?
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.
What is IRV
Inspiratory Reserve Volume
What is considered the normal threshold for FEV1/FVC%?
75% *If less than 75%, then this is considered lower than normal 80% *If greater than 75%, then this is considered close to normal 80%
What was the indicator used for lipid digestion?
Bromothymal blue
What organ does this belong to?
Liver
What was the indicator used for carbohydrate digestion?
Lugol’s solution
