What specific part of the kidney does the dialysis tubing represent what is this part function?
The dialysis tubing represents the kidneys filtration through the ureter which transports urine towards the urinary bladder.
What does the Congo red stain represent?
In histology and microscopy, Congo red is used for staining in amyloidosis, and for the cell walls of plants and fungi, and for the outer membrane of Gram-negative bacteria. Apple-green birefringence of Congo red stained preparations under polarized light is indicative of the presence of amyloid fibrils.
What does the Congo red represent at the end of the experiment?
What does the Congo red represent? The Congo red solution is used to mimic blood and the yellow food color mimics the excretory product of the kidney. At the end of the experiment, the contents in the dialysis bag represent the blood; the contents of the beaker represent the urine formed.
What does the dialysis bag represent?
1. What does the dialysis bag represent? The cell membrane.
How many functions do the kidneys have?
The kidneys perform many crucial functions, including: maintaining overall fluid balance. regulating and filtering minerals from blood. filtering waste materials from food, medications, and toxic substances.
What are the structural and functional unit of kidney called?
Nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood. There are about 1,000,000 nephrons in each human kidney.
What is direct stain?
The cell wall of most bacteria has an overall net negative charge and thus can be stained directly with a single basic (positively charged) stain or dye. This type of stain allows us to observe the shape, size and arrangement of bacteria. Staining is done at the sink.
What does the term dichroism in relation to amyloid staining with Congo Red mean?
Observations on Smears of Congo Red and Sections of Amyloid Stained by Congo Red. Smears and sections showed dichroism, meaning that the intensity of their red color depended on the plane of polarization.
How do you make a 1% Congo Red solution?
2.2. Preparation of Congo Red 1000 mg/L (stock solution) was prepared by dissolving 1 g of congo red in 1 Liter of distilled water. 20, 40, 70 and 100 ppm solution prepared by dilution from the stock solution.
Why is it important for the kidney to filter blood?
Remove wastes and extra fluid Your kidneys act like a filter to remove wastes and extra fluid from your body. Your kidneys filter about 200 quarts of blood each day to make about 1 to 2 quarts of urine. The urine contains wastes and extra fluid. This prevents buildup of wastes and fluid to keep your body healthy.
Which component of the urinary system is more lateral?
Urinary bladder – it is the more lateral because is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones.
What is the function of dialysis tubing?
Dialysis tubing is a semi-permeable membrane, usually made of cellulose acetate. It is used in dialysis, a process which involves the removal of very small molecular weight solutes from a solution, along with equilibrating the solution in a new buffer. This can also be useful for concentrating a dilute solution.
How does dialysis tubing represent a cell?
The dialysis tubing itself represents the cell membrane.
What is special about the dialysis tube?
Dialysis tubing is a type of tubing used in medicine to remove toxins from a patient’s bloodstream. It is effective for this purpose because it is a semipermeable membrane, allowing some particles to pass through while blocking others, and so can be used as a filter.
What do pre filled dialysis tubes represent?
The prefilled dialysis tubes will now represent cells. Fill in the data table with the percentage of sugar solution placed in them. Now take the mass of each dialysis tube and place it in its respective beaker. As you take each mass, record on the data table.
