filtration slits. - CORRECT ANSWER✔✔- Podocytes
Acute cystitis is best described as: - CORRECT ANSWER✔✔- Inflammation of the bladder
presenting with frequency, dysuria, and lower abdominal and/or Supra public, low back pain
Overactive bladder syndrome shows which of the following features? - CORRECT
ANSWER✔✔- Frequency, urgency, weak flow, and nocturia
The normal fasting plasma glucose is 100 mg/dL, and the renal threshold is 300mg/dL. If the
plasma concentration double to 200mg/dL, then: - CORRECT ANSWER✔✔- The rate at
which glucose is reabsorbed will double
An increase in mean arterial pressure (MAP) stimulates which of the following? - CORRECT

effect on GFR? - CORRECT ANSWER✔✔- Decreased GFR
Glucose reabsorption occurs primarily in the: - CORRECT ANSWER✔✔- Proximal
convoluted tubule
