Where are the vocal folds located?"

A. Glomerulus: The glomerulus is a high-pressure capillary bed in the nephron where filtration of blood occurs.

B. Bowman's capsule: This is the cup-shaped structure surrounding the glomerulus, not a capillary bed.

C. Vasa recta: These are capillaries surrounding the loop of Henle, involved in the reabsorption process, not filtration.

D. Macula densa: This is a group of specialized cells in the distal convoluted tubule that sense sodium concentration and affect glomerular filtration rate, but it is not a capillary bed.

A. The testes would not maintain the proper temperature: Temperature regulation of the testes is controlled by the scrotum and muscles, not the prostate.

B. The flow of urine may be blocked or slowed: Benign prostatic hyperplasia (BPH), or an enlarged prostate, can compress the urethra, leading to difficulty urinating or weak urine flow.

C. Seminal fluid would not have the proper pH: The prostate contributes fluids to semen, but BPH typically affects urine flow more than seminal fluid pH.

D. Sperm would not be allowed to fully mature: Sperm maturation occurs in the epididymis, not in the prostate.
