Quiz zum Vortrag
What percentage of nephrons are lost in aging kidneys?
- 30 to 50%
- 10 to 20%
- 50 to 70%
- 20 to 30%
- 60 to 80%
The normal bladder capacity drops from 600-800 milliliters to what range in older adults?
- 300 to 400 milliliters
- 200 to 300 milliliters
- 400 to 500 milliliters
- 500 to 600 milliliters

In benign prostatic hyperplasia, what happens to dihydrotestosterone (DHT) levels in prostate tissue as men age?
- DHT concentrates and accumulates in prostate tissue despite declining testosterone in the body.
- DHT levels decrease proportionally with testosterone throughout the body.
- DHT production stops completely in the prostate after age 65.
- DHT converts back to testosterone to maintain hormonal balance.
- DHT levels remain constant while testosterone increases in prostate tissue.
How do neurological changes in the aging brain affect bladder control?
- Frontal brain volume loss reduces control of when to urinate.
- Increased neurotransmitter production enhances bladder muscle coordination.
- Brain changes primarily affect kidney function rather than bladder control.
- Neurological changes only impact the physical sensation of bladder fullness.
- Brain aging improves the timing of urination signals to the spinal cord.
What is the primary reason that nephrons lose their ability to filter waste effectively in aging kidneys?
- Vascular blood supply to nephrons is reduced by half in patients over 80.
- Nephron cell walls become too thick to allow proper filtration.
- Increased blood pressure damages the filtering mechanisms permanently.
- Hormonal changes directly destroy the nephron filtering structures.
- Accumulated toxins block the nephron pathways over time.
