Intro to the Kidney MCQ
Question 1 |
What type of cell is present in the thick ascending loop of Henle?
Simple squamous | |
Simple cuboidal | |
Ciliated simple cuboidal | |
Simple columnar |
Question 2 |
A patient has nephrogenic diabetes insipidus. Which part of the uriniferous tubule is most likely to be affected?
Proximal convoluted tubule | |
Collecting duct | |
Thick ascending loop of Henle | |
Thick descending loop of Henle |
Question 3 |
What are the main ions contributing to the concentration gradient in extracellular fluid?
Calcium and bicarbonate | |
Potassium, phosphate and inorganic anions | |
Sodium and potassium | |
Sodium and chloride |
Question 4 |
What property of the epithelium in the proximal convoluted tubule is related to its function?
The thin layer of the simple squamous epithelium allows important molecules to diffuse more easily | |
The brush border of cuboidal epithelium maximises the surface area for absorption of molecules | |
The columnar epithelium ensure quick active transport of a high concentration of important molecules across the membrane | |
The stratified squamous epithelium helps to resist the wear and tear of high volume filtrate entering the PCT
|
Question 5 |
Which is not one of the four ways a substance is handled by the kidney?
Filtered | |
Filtered and partially reabsorbed | |
Filtered and completely reabsorbed | |
None of the above
|
Question 6 |
What would be the most likely long-term consequence of chronic kidney disease?
Anaemia of chronic disease | |
Liver cirrosis | |
Portal hypertension | |
Cancer |
Question 7 |
A decrease in blood flow to an interlobular artery could result from stenosis of which artery?
Arcuate artery | |
Afferent arteriole | |
Efferent arteriole | |
Vasa recta |
Question 8 |
How is urinary excretion rate altered by a high reabsorption rate?
It is increased | |
It is decreased | |
It does not alter urinary excretion rate | |
It is not part of the equation |
Question 9 |
Which of the following is not a function of the kidney?
Calcium homeostasis | |
Regulation of ECF sodium | |
Synthesis of ADH | |
Regulation of body fluid volume |
Question 10 |
How is urinary filtration rate calculated?
Urinary excretion rate = Filtration rate + Secretion rate + Reabsorption rate | |
Urinary excretion rate = Filtration rate - Secretion rate – Reabsorption rate | |
Urinary excretion rate = Filtration rate + Secretion rate – Reabsorption rate | |
Urinary excretion rate = (Filtration rate + Secretion rate) /Reabsorption rate |
