Physiology. Amylase is a calcium dependent enzyme which hydrolyzes complex carbohydrates at alpha 1,4-linkages to form maltose and glucose. Amylase is filtered by renal tubules and resorbed (inactivated) by tubular epithelium. Active enzyme does not appear in urine.
The prostate is an accessory sex gland that surrounds the urethra and neck of a male dog's bladder. The prostate gland produces a fluid that helps nourish and transport sperm. Benign prostatic hyperplasia is a condition in which the prostate gland is enlarged. The word hyperplasia means increased in size.
Anatomy and Physiology of the Prostate Gland. The prostate is located directly beneath the bladder and in front of the rectum. Because the upper portion of the urethra passes through the prostate, if the gland becomes enlarged it can obstruct the passage of fluid through the urethra.
