The reason that men who have enlargement of the prostate gland experience urinary symptoms is:.A. The prostate gland is part of the urinary system. B. The prostate gland presses on the urethra. C. The prostate gland blocks the bladder. D. The prostate gland surrounds the bladder neck and the urethra.

B. The prostate gland presses on the urethra

Explanation:

Benign prostatic hyperplasia (BPH) is caused by the proliferation of prostatic cells, which leads to the inflammation of this gland, squeezing the urethra (i.e., the tube where urine passes) and ultimately reducing the flow of urine. BPH is a chronic condition progressive with age, thereby it is associated with old men. Although in principle BPH isn't dangerous, high pressure on the urethra may lead to incomplete emptying bladder and infections in the urinary tract.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
