Which of the following is NOT a function of the urinary system?
Eliminate waste from the body
Regulate blood sugar levels
Maintain levels of electrolytes
Regulate blood pH
How does the urinary system contribute to regulating blood pressure?
By increasing insulin production
By filtering oxygen from blood
By regulating blood volume
By digesting proteins
Which balance do kidneys help maintain in the body?
Hormone and enzyme balance
Blood sugar and fat balance
Electrolyte and water balance
Protein and carbohydrate balance
What is the role of nephrons in the kidney?
Pump blood
Absorb nutrients
Filter the blood
Produce insulin
What process accompanies filtration in the kidneys to retain essential substances?
Secretion
Excretion
Reabsorption
Dialysis
Which of the following is reabsorbed back into the blood during reabsorption?
Only waste products
Water, sodium, and glucose
Only proteins
Only oxygen
Which substances are reabsorbed in the proximal convoluted tubule?
Only amino acids
Glucose
Only mineral salts
Only metabolic waste
What is the main role of reabsorption in the nephron?
Removing excess proteins from the blood
Reclaiming useful substances back into the blood
Storing urine before excretion
Filtering large molecules from blood
Where does glucose reabsorption primarily occur in the kidney?
Loop of Henle
Distal Convoluted Tubule
Proximal Convoluted Tubule (PCT)
Collecting Duct
Which protein is responsible for glucose reabsorption in the kidneys?
GLUT4
Sodium-Potassium Pump
Aquaporin
Sodium-Glucose Co-Transporter 2 (SGLT2)
In diabetic individuals, what is the issue with glucose reabsorption?
Glucose is not filtered by the kidneys
Kidneys reabsorb too little glucose
Kidneys reabsorb too much glucose through SGLT2
Glucose is completely excreted in urine
What is the consequence of excessive glucose reabsorption in diabetes?
Low blood glucose
Normal blood sugar levels
High blood sugar
No change in glucose levels
Inhibition of SGLT2 leads to which of the following physiological outcomes?
Increased glucose reabsorption in the kidneys
Increased glucose excretion in urine
Decreased urine output
Increased hepatic glycogen synthesis
Decreased plasma ketone levels
What is the protein responsible for the reabsorption of glucose in the proximal renal tubule that is inhibited by SGLT2 inhibitors?
SGLT2 inhibitor
SGLT1
SGLT2
Insulin receptor
Glucokinase
Which of the following effects is achieved due to reduced glucose reabsorption by SGLT2 inhibitors in patients with diabetes?
Increase in blood sugar (glycemic levels)
Reduction in blood sugar (glycemic levels)
Increase in insulin resistance
Increase in hepatic glucose output
Decrease in urinary glucose excretion
